Key Verse “…and the Holy Spirit descended on him in bodily form like a dove. And a voice came from heaven: “You are my Son, whom I love; with you I am well pleased.” Luke 3:22
The doctrine of the trinity is one of the most important doctrines of Christianity. It was established early on as discussion over the deity of Christ and the deity of the Holy Spirit abounded. It was decided that the Father, Son, and Spirit were all equally God and anyone who claimed otherwise was a heretic.
Despite being a cornerstone to our Christian faith, the trinity is something that is hard for us to grasp. How can God be three persons, or how could He have three forms?
The Jews struggled with this concept because they saw teaching of the trinity to be heretical and polytheism – the worship of more than one god. Deuteronomy 6:4 has been strongly ingrained into their minds. “The Lord our God is one…”
The doctrine of the trinity is not actually taught in scripture, which makes this all the more difficult to accept. But for the writers of the New Testament, it wasn’t an issue that they felt they had to deal with. There was no argument because there is so much circumstantial evidence. Our key verse shows all three persons of the Godhead in the same place at the same time. The Holy Spirit descends upon Christ while the Father speaks from heaven.
The Father and Son
The fact that Christ is God was central to the reason Jesus was crucified. His claim in John 10:30 was cause for the Jews to pick up stones to stone him. Although it was considered blasphemy, Jesus claim to be God was never misunderstood by even the unbelieving Jews.
As we read the account of creation, it appears to just be GOD doing all the work. However, all three persons of the Godhead were present and active in creation. John 1:3 tells us that all things came into being through Him (the Word – that is Christ). Genesis 1:2 shows the spirit hovering over the waters.
Although it should not be considered conclusive evidence, the name for God used in creation, Elohim, is a plural word in Hebrew. Likewise, in Genesis 1:26 God says “Let us create man in our image.”
The big picture
Our God is so big and incomprehensible that despite our best attempts we can only begin to grasp who He is. In our human minds 1+1+1 does not equal 1. However infinity + infinity + infinity = infinity. We worship an infinite God that is greater than we can grasp.
