- The Trinity was the primary topic of the Council of Nice around 325. There were those who began to question the Diety of Christ. Primarily Arius and Sebelius. The council and most Trinitarians (of which I am) find their support from Scripture in the following places: Christ is God - John 1 and was with God at creation Christ is of the same substance of God - John 3:16, 1 John 4. So John 1 is a straight forward verse, I won't spend time on that. The pivotal pointer is John 3:16 is the term begotten. Begotten implies that Christ was of the same substance as God the Father and therefore all the attributes of God (God in this sense is the trinity, not The Father, The Son, or the Holy Spirit) apply to Christ. One of those is eternality, not just future, but past or put another way He never did not exist. This was the key in the conversation with Arius and his follower in that they believed "there was a time when Christ was not." From a paper I wrote a couple years ago: The eternality of Christ is best stated in John 1 as John is plain in asserting that Christ was God and was from the beginning. That in Christ all came into existence, much like in Genesis 1 where God created everything, John reinforces the fact that Christ was God and was present at creation, not part of creation. Christ Himself states that He and The Father are one (John 10) in which Christ is stating one, or whole, or one unit. The very essence of God is in Christ, and for the essence of God to be in Christ, the eternality of God must also be in Christ. The term begotten as used in places such as 1 Jn 4, John 3:16 is a reference to “One and only of His kind.” Of His kind implies that there is essence that is the same between The Father and The Son, they are of the same hypostasis or ousia. if we study the New Testament, we will see that Christ Himself made no bones about that He was and is God. While in many cases, it may seem to us that there are few direct statements to this effect, that is not the case. There are many direct statements "I and the Father are One", but there are many that to us are missed as we are not Jews. The reading of Scripture in Luke 4 while we do not see it, the implication was clearly that Christ was God. This is why people were angry. The raising of Lazarus was one that is lost on most, as the common belief was that a person's Spirit hovered over a person for three days and then left, it was only God who could raise someone from the dead after that time. Christ waited until it was (based on belief) that only God could raise Lazarus. There is continual acts and actions which reenforce that Christ was God. Where the Spirit is concerned, we have to look at how He is presented and what is said about Him. Again if we look at Scripture we see that the Holy Spirit if the Spirit of God, not a spirit of God, but The.
