On the contrary, the Trinity doctrine is a contradiction.
For myself, I find the Trinity doctrine central to understanding how God justifies us in Christ's death, giving us through His Spirit eternal life. I find the surety of this understanding - God Himself incarnated in a man, to provide His body in sacrificial death for us, that we can join with Him, and be filled with Him in His Holy Spirit. Actually united to Him, our Loving Creator, in mystical union, that we be one, even as they are One. An amazing truth! One which assures us of the power of a new life in Christ. We are alive in the spirit because we are alive in Christ, It's God's Own Spirit life that gives us our life, and forever will. Not like Adam. Like the Last Adam.
There is no Biblical support for the Trinity Doctrine, only verses taken out of context.
I find that when I look at the great number of verses that give us information on Father, Son, and Spirit, I find the Trinity doctrine inescapable. There are quite a number of things that are attributed to each, did you know that? God raised Jesus from the dead, that is plainly stated. Jesus also raised Himself. The Spirit raised Him. Each is true. None conflict. The same is true of creation, salvation, many more.
For me this is more a matter of How we think about God. I don't think we have to understand all the things the Bible says, but we should be reading it for what it says and not what it does not say, and we should allow our minds to be formed according to what we read.
When we read that the Word became flesh, we know this is Jesus, and when we read God was the Word, we know this is Jesus, and we think of Him accordingly, and as we proclaim with Thomas, My Lord and my God, we don't have to somehow explain away these texts as something us, even IF we have no idea how the Father is God, and Jesus is God.
And when we read, the Holy Spirit said to separate out Paul and Barnabas for the work they have to do, and that Ananias lied to the Holy Spirit, lying to God, again, we don't need to look for some hidden "real" meaning, we just accept it as written, and allow our minds to be formed.
The things I see people point to as contradictions I don't see that way. For instance, Isn't the Son worshiping the Father God worshiping Himself? The Son emptied Himself and took on flesh, and all that came with it, including the commandments, and including the proper human relationship with God. Jeremiah spoke of the LORD being God of all flesh, and Jesus took on flesh. He really did humble Himself, taking the form of a servant.
I realize that God must enlighten our minds. I try to encourage that we read the text in what it says, and accept those things it says. When we find what seems contradiction, find the harmony that preserves the meaning held in all the passages.
Much love!
