You seem like a guy who doesn't care much for creeds or historical christianity or traditions. Fine by me.
I would just keep it biblical with you.
Lets go with these few verses:
1 Timothy 3:16 And without controversy great is the mystery of godliness:
God was manifest in the flesh, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory.
John 1:1,14
In the beginning was the Word, and the Word was with God, and the Word was God.
And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
What we can learn from these verses, is that God was manifest in the flesh, and how was it manifest? Thru Jesus, the son of God.
"the Word" was with God at the moment of creation, John tells us this Word was God, which was then made flesh and dwelt among us (Jesus)
I think thats a really simple and biblical way of looking at it. I realize the talk of substances and persons and divine essence is completely unbiblical and can be very confusing. Me im a theology nerd so I enjoy listening to things like that.
For those who do enjoy, I once again recommend Beau Branson's speeches on the topic. Him and I are in agreement when it comes to what "the trinity" is.
Here is a link to it, includes multiple videos I subscribe to the eastern view of the trinity as it can be easily defended against accusations of tritheism, whereas the western view is way too open to that accusation, especially today when people are unlearned, easy food for the JWs and muslims of the world.
