The Bible story tells us how God began to reveal himself over a period of time through appearances to individuals, beginning with Abraham (Genesis 12), and through certain historical events, chiefly concerning Abraham's descendants, the Israelite (Jewish) people. The Jewish people were very strong in the belief that the God who had brought them out of slavery in Egypt, met with them at Mount Sinai, given them his commandments, and who had brought them into the promised land, was the one true living God of all the earth. This was in contrast to the many gods that the surrounding nations worshipped.
Over the years God foretold through the prophets, particularly from the eighth century BC onwards, that a figure would arise among them who would bring many blessings to God's people, whether they were Israelites or from among the nations of the world. "The virgin will be with child and will give birth to a son, and will call him Immanuel" (Isaiah 7:14 - Immanuel means "God with us" in Hebrew). "For to us a child is born, to us a son is given, and the government will be on his shoulders. And he will be called Wonderful Counsellor, Mighty God, Everlasting Father, Prince of Peace" (Isaiah 9:6). "I ...will make you to be a covenant for the people and a light for the nations" (Isaiah 42:6).
Several centuries later, during the reign of the Roman emperor Caesar Augustus, a child was born in the Jewish village of Bethlehem. At the age of 30 this individual, Jesus, began his public ministry and astounded people, both with his miracles of healing and with his claims*. These claims included the assertion that he was the one foretold through the Old Testament writings (e.g. John 5:39,40). He said many things about himself that the Jewish religious leaders rightly recognised as putting himself on a level with God. On a number of occasions they were ready to stone him for blasphemy for making such claims. At the same time he often talked about his "Father" in heaven who had sent him into this world. Of course, if the claims of Jesus are true, then God is no longer one person, but two!
However, before Jesus was crucified, he promised his disciples that he would ask the Father to send them "another Counsellor to be with you forever - the Spirit of truth. The world cannot accept him, because it neither sees him nor knows him. But you know him, for he lives with you and will be in you" (John 14:16,17). It is interesting that the Greek** word "another" that is used here implies "another like me". This "Spirit" that Jesus spoke of came to indwell the disciples of Jesus fifty days later on the Jewish Day of Pentecost.
Now all this complicates the matter even further, for if the Spirit is also God and distinct from the Father (and we will explore this later), then we now have not just two persons, but three! For Jews who had been steeped in the Jewish tradition of one God, this must have been all rather confusing. But as the rest of the New Testament indicates, after Pentecost the early disciples of Jesus, particularly those he had trained for leadership in this new community, got it all sorted out reasonably quickly. To this evidence we now turn.
In the following pages we will look at what the New Testament has to say about the following questions:
Is Jesus really God?
Is the Holy Spirit really God?
Is the Holy Spirit personal?
Is the Holy Spirit distinct from God the Father?
Jesus is God
There are many approaches one can take when exploring this question in the New Testament. Here are some of them:
His remarkable claims (see Is Jesus really God).
He is constantly given the title "Lord", the word that was consistently used of God in the Greek translation of the Old Testament of the third century BC.
He is referred to as God a number of times (e.g. John 20:28). Paul can declare, "in Christ all the fullness of the Deity lives in bodily form" (Colossians 2:9). John says, "He (Jesus) is the true God and eternal life" (1 John 5:20). In the Old Testament he is called "the mighty God" (Isaiah 9:6) the same two Hebrew words used of God in a number of places (e.g. Isaiah 10:21; Jeremiah 32:18).
His pre-existence before coming into this world is constantly assumed and sometimes directly stated (e.g. John 1:1,14).
He was involved in the creation of the universe and it is his power that sustains it (e.g. Colossians 1: 16,17; Hebrews 1: 2,3).
His role as judge of the human race (e.g. John 5:25-29; 2 Corinthians 5:10).
His achievements in reconciling men and women to God and meeting their needs on the journey through life are often described in the same terms as the achievements of God the Father. Their roles often overlap (e.g. 2 Corinthians 5:19; and compare Hebrews 8:12 with Mark 2:5-7). That Paul, an avowed monotheist, should attribute every imaginable activity to him that Judaism reserved for God alone is particularly significant.
There are numerous passages showing that we are to give him the same love, loyalty and devotion that we are required to give to God.
He receives the same worship of created beings, in heaven and on earth, as does God the Father (e.g. Revelation 5:11-14 - Jesus is constantly referred to as "the Lamb" in Revelation, the one who was sacrificed for us).
There are quite a number of passages from the Old Testament, quoted in the New Testament, where the original references refer to God, while the New Testament writers refer them to Jesus (e.g. Matthew 21:15,16/Psalm 8:1,2; Philippians 2:9-11/Isaiah 45:22,23).
There are numerous titles or metaphors used of Jesus that are also used of God, such as Saviour, Rock, Light, the Bridegroom, the first and the last, Alpha and Omega, I am, King of Kings and Lord of Lords, Shepherd, Master, etc.
The fact that Paul, a person steeped in the Old Testament understanding of the Spirit of God, should so easily call him the Spirit of Christ as well, is as strong a confirmation as one could get of Christ's full divinity (e.g. Romans 8:9).
There is much more that could be said on the divinity of Jesus. However, more people have difficulty with the Holy Spirit than they do with Jesus. After all, Jesus did and said things that only God could be expected to do and say. But also he was always talking about his Father in heaven, so is obviously someone distinct from the Father. The New Testament writers distinguish Jesus from God the Father at every stage of his career - his pre-existence (John 17:5), through his presence on earth, to his ascension into heaven (1 Peter 3:22).
But who is the Holy Spirit? A student expressed his uncertainty this way, "God the Father makes perfectly good sense to me; and God the Son I can understand; but the Holy Spirit is a grey, oblong blur." I will focus the rest of this section on exploring the biblical picture that is given to us of the Holy Spirit.
The Holy Spirit is God
To begin with, the very fact that his full title is the Holy Spirit (used about 90 times in the New Testament) points to his divinity. God is supremely the Holy One in the Bible (Isaiah 57:15). Jesus spoke of the Spirit as the Holy Spirit, as he was later to address God as Holy Father (John 17:11). In this respect Ephesians 1:13 is a significant passage. In the Greek it literally reads, "the Spirit of the promise, the Holy." Both "the promise" and the adjective "holy" are emphasised in the Greek word order. He is not only the one promised by the prophets, he is God himself who has come to live with and in his people. Significantly, Jesus is also "the Holy One" (Acts 3:14).
He is often referred to as "the Spirit of God" in both Old and New Testaments.
The New Testament writers can quote passages from the Old Testament in which God speaks and say, "The Holy Spirit spoke" (e.g. Acts 28:25-27/Isaiah 6:8-10).
Paul's language can fluctuate between God, Christ, and Spirit, depending on the emphasis of a given passage. For example, he can speak of the power of God (2 Corinthians 4:7), the power of Christ (2 Corinthians 12:9) or the power of the Holy Spirit (Romans 15:19), all of which are at work in his life. This says much about how Paul viewed Christ and the Spirit in terms of deity and inter-relationship. Or note 1 Corinthians 12, where the subject changes from God in verse 6, to the Spirit in verse 11. Similarly in Acts 5, to lie to the Holy Spirit (verse 3) is to lie to God (verse 4).
Whereas in the Old Testament the temple building signified the place where God lived among his people, in the New Testament the body of believers is the new temple, the place where the Holy Spirit lives in his people (1 Corinthians 3:16; Ephesians 2:21,22). In the New Testament there is no difference between the way the presence of the Holy Spirit is spoken of and the presence of God. The presence of the Holy Spirit is the presence of God.
One of the most significant descriptions of the Holy Spirit in the New Testament is "the Spirit of life" (Romans 8:2). He is the one who "gives life" (2 Corinthians 3:6). God in the Old Testament is supremely the living God, the source of life in all that lives. The Holy Spirit is the Spirit of life because he is the Spirit of God. Significantly, Jesus is also spoken of as "the author of life" (Acts 3:15).
There are some offshoots from Christianity, such as Jehovah's Witnesses, Christadelphians and Unitarians that deny the traditional church teaching of the Trinity. The Jehovah's Witnesses believe that Jesus was created by God the Father before the creation of the universe. He is a minor God. According to them the Holy Spirit is distinct from God the Father, but he is in no sense personal. He is merely God's active force which he uses to accomplish his purposes in the world. Let us explore this issue.
The Holy Spirit is Personal
By "personal" we understand that the Holy Spirit has all the qualities that we usually associate with persons. We can enter into a relationship with him in a similar manner to the way we have relationships with other people. He is not just a blind, unfeeling, unintelligent force. This presents us with a problem, because in our thinking persons usually live in bodies, and the Holy Spirit is spirit, as is God the Father, and doesn't have a material body. He lives in a different dimension to that with which we are familiar.
"We can enter into a relationship with him in a similar manner to the way we have relationships with other people"Jesus is easier to understand, as he entered into our human experience, which involved sharing human nature and a human body. Obviously he was a person. However, when we explore the New Testament we find that the Holy Spirit is constantly spoken of in personal terms. The most obvious example of this is found in the use of the verbs that describe his activities.
Take the following examples:
The Spirit convicts people of guilt and judgement (John 16:8)
guides God's people (John 16:13)
tells things that are to come (John 16:13)
brings glory to Jesus (John 16:14)
hears God's truths and makes them known (John 16:13,15)
appoints pastors over God's people (Acts 20:28)
speaks God's message (Acts 28:25, etc.)
bears witness together with our own spirits (Romans 8:16)
helps us in our weakness (Romans 8:26)
intercedes on our behalf (Romans 8:26, 27)
searches all things (1 Corinthians 2:10)
knows the mind of God (1 Corinthians 2:11)
teaches the content of the gospel to believers (1 Corinthians 2:13)
lives among and within believers (1 Corinthians 3:16, etc.)
washes, sanctifies and justifies God's people (1 Corinthians 6:11)
gives gifts to his people as he determines (1 Corinthians 12:11)
gives life to those who believe (2 Corinthians 3:6)
cries out from within our hearts (Galatians 4:6)
leads us in the ways of God (Galatians 5:18)
has desires that are in opposition to the flesh (Galatians 5:17)
strengthens believers (Ephesians 3:16)
is grieved by our sinfulness (Ephesians 4:30)
can be blasphemed (Luke 12:10) and lied to (Acts 5:3)
The Bible is more concerned to describe the Spirit's activity, what he does, than to deal directly with the question of his person, who he is. However, it is obvious that all these activities are those we associate with persons. They imply:
Intelligence - most of the verbs used above imply intelligence. The Bible speaks of "the mind of the Spirit" (Romans 8:27)
Feelings - he can be grieved or made sad. Joy is a quality often associated with the Holy Spirit
Will - he decides the gifts he gives to his people (1 Corinthians 12:11)
These are the three main characteristics which make up personality.
Several significant passages that emphasise the personal nature of the Holy Spirit:
"The Spirit himself testifies with our spirit that we are God's children" (Romans 8:16). If our own inner spirit has personal qualities, then so also must the Holy Spirit. Both "testify".
"...you were justified in the name of the Lord Jesus Christ and by the Spirit of our God" (1 Corinthians 6:11). If Jesus is personal, then the Holy Spirit must be also.
In Romans 8 the Spirit in our hearts prays for us on earth (verse 27), while Jesus prays for us in heaven (verse 34). This again suggests that as Jesus is a person, so is the Spirit.
"I speak the truth in Christ - I am not lying, my conscience confirms it in the Holy Spirit" (Romans 9:1). Paul here appeals to his relationship with both Christ and the Holy Spirit for his honesty, implying that as Christ is personal, so must the Spirit also be. Another verse with similar implications is Romans 15:30.
Jesus said the disciples would be better off with the presence of the Holy Spirit in their lives than they were with his company and friendship while he was with them on earth (John 16:7). That means the Spirit must at least have the personal qualities that Jesus possessed.
It is significant that the "fruit" that the Spirit produces in believers' lives, "love, joy, peace, patience, kindness, goodness, faithfulness, gentleness and self-control" (Galatians 5:22,23), are chiefly personal qualities, having to do with our relationships. They are also qualities often attributed to God in his relationship with us. A blind "force" or "influence" does not produce love! The Bible also speaks of the "fellowship of the Spirit" (2 Corinthians 13:14; Philippians 2:1). We may enjoy friendship with him and he creates friendship between believers.
It is true that to describe the effect of the Holy Spirit in our lives, the Bible does use impersonal metaphors such as fire, breath, wind and water. However, it is significant that Paul, who probably has more to say about the relationships that exist between the persons of the Trinity than any other writer, tends to avoid such images. Instead he uses verbs of personal action that are used elsewhere of God and Christ.
If the Holy Spirit is personal, as all the evidence indicates, then the next question to ask is: Is he a distinct person, in a very real sense separate from the Father?
The Holy Spirit is a distinct person from God the Father
A good beginning point here is to note the number of passages in the New Testament that mention all three persons of the Trinity together, often within the space of either one or two verses. The following is a list of such passages. It is not an exhaustive list as there are other passages where two of the persons are mentioned, but the presence of the third can be assumed by implication. Having listed these passages, I will look at several which are especially significant.
Matthew 3:16,17 1 Corinthians 6:9-11 Hebrew 2:3,4 Matthew 28:19 1 Corinthians 12:4-6 Hebrew 3:6,7 Luke 1:35 2 Corinthians 1:21,22 Hebrews 6:4-6 Luke 1:67-69 2 Corinthians 3:3, 4 Hebrew 9:14 John 14:16,17 2 Corinthians 5:5-10 Hebrews 10:12-15 John 14:26 2 Corinthians 13:14 Hebrews 10:29-31 John 15:26 Galatians 3:1-5 1 Peter 1:2 John 16:13-15 Galatians 3:11-14 1 Peter 3:18 John 20:21,22 Galatians 4:4-6 1 Peter 4:14-17 Acts 2:33 Ephesians 1:3-14 2 Peter 1:21-2:1 Acts 2:38,39 Ephesians 2:18 1 John 3:21-24 Acts 7:55 Ephesians 2:22 1 John 4:1,2 Acts 10:38 Ephesians 3:4-7 1 John 4:13,14 Acts 10:46-48 Ephesians 3:14-19 1 John 5:6-9 Acts 11:16,17 Ephesians 4:2-6 Jude 20,21 Romans 5:5,6 Ephesians 5:18-20 Revelation 1:4,5 Romans 8:3,4 Colossians 1:7-10 Revelation 1:9,10 Romans 8:8-11 1 Thessalonians 1:5-10 Revelation 2:7 Romans 8:16,17 1 Thessalonians 4:1-8 Revelation 2:26-29 Romans 14:17,18 1 Thessalonians 5:18,19 Revelation 3:5,6 Romans 15:16 2 Thessalonians 2:13,14 Revelation 3:12,13 Romans 15:17-19 1 Timothy 3:15,16 1 Revelation 3:21,22 Romans 15:30 Timothy 4:1-6 Revelation 5:6,7 1 Corinthians 2:8-10 2 Timothy 1:8-14 Revelation 14:12,13 1 Corinthians 2:12-16 Titus 3:4-8 Revelation 22:16-18 The very fact that so many passages can refer to each of the three persons of the Trinity, with each having a distinctive role in our salvation, is the strongest possible evidence that the Holy Spirit is distinct from God the Father, just as Jesus is distinct from God the Father.
The following passages are particularly significant:
At the baptism of Jesus we read, "...he saw the Spirit of God descending like a dove and lighting on him. And a voice from heaven said, 'This is my Son, whom I love...'"(Matthew 3:16:17). You will note that the Spirit descends on Jesus to empower him for his public ministry, while God the Father speaks from heaven.
Jesus' final commands to his disciples, recorded in Matthew's Gospel, includes the command to baptise converts, "in the name of the Father and of the Son and of the Holy Spirit" (Matthew 28:19). Baptism signifies our initiation into the divine family. I will explore some of the implications of this further in Part 2. Baptising "into the name" (literal translation) is a Hebrew form of expression. Note that it includes under a singular name not only the Father, but the Son and the Holy Spirit.
"In certain ways we are weak, but the Spirit is here to help us. For example, when we don't know what to pray for, the Spirit prays for us in ways that cannot be put into words. All our thoughts are known to God. He can understand what is in the mind of the Spirit, as the Spirit prays for God's people. We know that God is always at work for the good of everyone who loves him" (Romans 8:26-28). This passage expresses the remarkable truth that when our praying is prompted by the Holy Spirit we are caught up in the free and open communication that takes place between two members of the Trinity, the Holy Spirit and God the Father. Both of these desire our good. One writer, Martin Smith, puts it this way:
Our prayer is not making conversation with God. It is joining the conversation that is already going on in God. It is being invited to participate in the relationships of intimacy between the Father, Son and Holy Spirit. There is an eternal dance already in full swing, and we are caught up in to it. Prayer is allowing ourselves to join the dance and experience the movements, the constant interplay of the Persons of the Trinity.
You will note in the above passage that God knows the mind of the Spirit. In 1 Corinthians 2:11 the Spirit similarly knows the thoughts of God the Father. This is distinction, not identification. God the Father does not pray to himself. Nevertheless, the Spirit and God the Father act in harmony.
"Now there are varieties of gifts, but the same Spirit. And there are varieties of ministries, and the same Lord. And there are varieties of effects, but the same God who works all things in all persons" (1 Corinthians 12:4-6). In these verses, and those following, Paul is pointing out to the Corinthian believers the wide range of gifts and ministries that are given to individuals in the Christian fellowship, even though they are one united body. His appeal to unity is based on the fact that these gifts and ministries all have their source in members of the divine Trinity. His appeal for the need for variety is based on the fact that variety exists even within the Godhead itself. Diversity within unity belongs to the character of God. The Trinity is foundational to Paul's whole argument.
C. K. Barrett notes of this passage in his Harper's New Testament Commentary on 1 Corinthians, "The Trinitarian formula is the more impressive because it seems to be artless and unconscious." Gordon Fee, one of the world's leading textual critics, in his impressive volume God's Empowering Presence: The Holy Spirit in the Letters of Paul, adds, "...passages like this are the 'stuff' from which later theological constructs are correctly derived."
"May the grace of the Lord Jesus Christ, and the love of God, and the fellowship of the Holy Spirit be with you all" (2 Corinthians 13:14). Here is one of the clearest references to the Spirit as one of the three Persons of the Godhead, each of whom is designated by that special ministry that belongs to him. That Paul can refer to the activity of the three divine Persons together in one prayer, with God the Father standing in second place, is as strong evidence as one could get that Paul was truly Trinitarian in his thinking. Gordon Fee comments:
That Paul would include the Holy Spirit as an equal member of this triadic formula, and that he would pray to the Spirit in their behalf, says as much about his understanding of the Spirit both as person and as deity as any direct statement of this kind ever could...It is for the later church to try to understand the ontological implications, how God is three in one; its reason for doing so at all comes about precisely because the church is forced to come to terms with Paul's understanding of God's character and activity in our behalf expressed in this kind of prayer.
"Be completely humble and gentle; be patient, bearing with one another in love. Make every effort to keep the unity of the Spirit through the bond of peace. There is one body and one Spirit - just as you were called to one hope when you were called - one Lord, one faith, one baptism; one God and Father of all, who is over all and through all and in all" (Ephesians 4:2-6). Paul wants the believers in Ephesus to develop those personal qualities that will enable them to demonstrate to the outside world a true unity of love. The fact that they are one body, and should be seen to be so, he argues, is based on the fact that there is, "one Spirit...one Lord...one God and Father of all."
This passage puts into credal form the fact that God is experienced as a triune reality. It is the Spirit coming into our lives who builds us into one body or fellowship; it is Jesus, who died for us, in whom we put our faith for forgiveness and acceptance; and it is God the Father over all to whom we look for guidance and provision.
"How much more, then, will the blood of Christ, who through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death, so that we may serve the living God" (Hebrews 9:14). It is the eternal Spirit, who empowered Jesus at his baptism for his public ministry, who enabled him to offer himself to God as a perfect sacrifice for our sins on the cross. Here again, the Spirit is clearly distinct from God the Father. Each had their part to play in our salvation.
"Grace and peace to you from him who is, and who was, and who is to come, and from the seven spirits before his throne, and from Jesus Christ, who is the faithful witness, the firstborn from the dead, and the ruler of the kings of the earth" (Revelation 1:4). John begins this remarkable letter with a prayer that his readers may receive grace and peace from each of the Persons of the divine Trinity. The Holy Spirit is presented here as the seven-branched candlestick that stood before the Most Holy Place in the temple of the Old Testament. This is in line with the symbolism that pervades the book of Revelation, most of which is taken from Old Testament temple worship. "Seven" in Revelation is the number of perfection, completion or fulfilment. Jesus is probably mentioned last in this passage as most of the rest of the book is about him. There could hardly be a clearer statement of the divinity of, and distinction between, the three Persons of the Trinity.
It should be becoming increasingly clear that Trinitarian language and ideas keep popping up constantly through the New Testament. The writers don't use the word "Trinity". Nor do they set out to explain the Trinity. That was left to later generations, however successful, or otherwise. (Who can explain God?) It was just that their experience of Jesus and all he had taught, and all they had experienced since the Holy Spirit had been given to God's people on the Day of Pentecost, clearly led in this direction.
J. Murray, in his Commentary on Romans in the New International Commentary, when speaking of Paul's description of the work of the three Persons of the Trinity in Romans 15:17-19, says:
It is not a case of artificially weaving these persons into his presentation; it is rather that his consciousness is so formed by and to faith in the triune God that he cannot but express himself in these terms.
This could be said of other writers of the New Testament.
Points for clarification
There are four other matters that require some clarification before moving on to Part 2.
The unity of the Trinity
Though each of the Persons of the Trinity exercises a different role in meeting our needs and preparing us for future glory, these roles often overlap. They exist in a unity of love, and all their purposes towards us are achieved in harmony with one another. Thus, Jesus can say, "I and the Father are one" (John 10:30). Often similar activities are attributed to different Persons of the Trinity. As the Holy Spirit is so intimately associated with both God the Father and Jesus, he is not only called "the Spirit of God", but also"the Spirit of Christ" (Romans 8:9; Galatians 4:6; Philippians 1:19). Paul can sometimes use a form of shorthand. Instead of saying, "Christ lives in his people by the Spirit", he simply says that Christ lives in his people (e.g. Romans 8:10; Galatians 2:20).
The submission of Jesus to the Father
"While Jesus lived on earth the Father was greater then he. That was Jesus' choice, for our eternal good"There are those who argue against the traditional understanding of the Trinity by pointing out those passages in the New Testament where Jesus is spoken of as being in submission to the Father. He declared that the Father had sent him (John 5:30), that he only did what the Father told him to do (John 12:49), and that the Father was greater than he (John 14:28).
This is explained by Paul in Philippians. "Jesus...being in very nature God, did not consider equality with God something to be grasped, but made himself nothing, taking the very nature of a servant, being made in human likeness...he humbled himself and became obedient to death - even death on a cross" (Philippians 2:6-8). In order to reconcile us to God and lift us up to his level, he came down to our level. He took upon himself our full humanity. "Since the children have flesh and blood, he too shared in their humanity...he had to be made like his brothers in every way... "(Hebrews 2:14-17). That meant that he behaved towards his heavenly Father in the manner in which we are meant to behave, in submission and obedience. That he was willing to take not only our human nature on himself, but also the consequences of our sins, demonstrates the amazing self-giving love and condescension of God. While Jesus lived on earth the Father was greater than he. That was Jesus' choice, for our eternal good.
In the same way the Holy Spirit chooses to submit himself to both the Father and the Son. One of his chief ministries is to focus our attention on Jesus, rather than himself. Thus, Jesus can say of the Spirit, "He will bring glory to me by taking from what is mine and making it known to you" (John 16:14). This submission in love, for our benefit, is in no way inconsistent with the full divinity of each. Rather, it is an example of the way we ought to behave towards one another (Philippians 2:5)!
Glimpses of the Trinity in the Old Testament
The Trinity is not something that the writers of the New Testament thought up, and which contradicts all that God had revealed to his people over preceding centuries. There are hints of the Trinity in the Old Testament which can be seen more clearly in the light of the fuller revelation of God that came to us through Jesus. The idea of the Trinity did not take God by surprise!
Of the 377 instances of the Hebrew word for breath, wind and spirit in the Old Testament, there are approximately 94 that refer to the Spirit of God. His activity there is associated with God's power in creation or in the lives of individuals. He equips people for leadership, inspires prophecy and the revelation of God's truth through chosen individuals. He is the presence of God with his people. These activities are also associated with the Holy Spirit in the New Testament. His coming to indwell God's people in a new way, as happened on the Day of Pentecost (Acts 2), was clearly foretold (Jeremiah 31:31-34; Ezekiel 36:25-27).
There are many prophecies about the coming of Christ throughout the Old Testament. There are times when God appears to individuals in human form (e.g. Joshua 5:13-15; Daniel 10:4-11). Some would see here the appearance of the second Person of the Trinity, Jesus, prior to his literal taking of human nature in Bethlehem.
Some would see hints of the Trinity in the plural term "us" used for God (Genesis 1:26), or in the threefold "Holy, holy, holy" of the angel's worship (Isaiah 6:3). It is interesting that the Hebrew word translated "one" in the famous statement of Deuteronomy 6:4, "Hear, O Israel: The Lord our God, the Lord is one," that precedes the command to love him with all our heart, soul and strength, is a word that does not necessarily mean "one single individual". It is a word that "stresses unity while recognising diversity within that oneness" (Theological Wordbook of the Old Testament: Harris, Archer, Waltke).
Not an invention of the fourth century church
Some have tried to argue that it was the church of the fourth century that came up with the idea of the Trinity and that we have been stuck with it ever since - except for those groups that have "seen the light". This is simply not historically accurate. All the pointers towards the truth of the Trinity were there in the personal experiences of the first Christians and the New Testament writings right from the beginning, as I have sought to show.
The First Council of Nicaea (now Isnik in modern Turkey) held in AD 325, which spelled out the doctrine of the Trinity in its simplest credal form (known to us today as the Nicean Creed), was called by the Emperor Constantine because of divisions that had arisen among Christians. These divisions had arisen largely because of the teaching of a priest, Arius, who taught truths that were contrary to the generally accepted views of the church. Specifically, he taught that Jesus was inferior to God the Father. His views were rejected by the Council. Of all the bishops present at Nicaea (traditionally 318, though the exact number is uncertain) only two failed to subscribe to its decision.
The debate at Nicaea centred largely around the person of Christ. The Creed, one of the few authentic documents to survive from the Council, contains declaration of belief "in the Holy Spirit" without elaboration. Other creeds written over the following hundred years developed further emphasis on the person and ministry of the Holy Spirit.
Of the early Church Fathers, Irenaeus and Origen share with Tertullian the responsibility for the formulation of the doctrine which later was expressed in the creeds. Athanasius led the debate at Nicaea. At the hands of Augustine a century later it received a formulation, enshrined in the Athanasius Creed, that is accepted by Trinitarian churches to this day. After receiving further elucidation at the hands of John Calvin it passed into the Reformed faith.
It is important to state that all this debate was undergirded by appeal to the writings of the New Testament. The ultimate decisions were made on the basis of the teaching of Jesus and his apostles.
