Regardless of what you've written, if it hasn't got a verse in it that shows that I have to believe in the trinity to be saved then I don't have to, and you and others have no right to condemn me or anyone else for not believing in it!
John 1-1 states: "In the beginning was the Word, and the Word was with God, and the Word was God."
I don't believe that one NEEDS to have a clear understanding of the Trinity to become part of the Body of Christ, however, I personally believe that there are three different entities involved. God the Father, God the Son, and God the Holy Spirit. John 1-1 speaks of the WORD, which is Christ. It states that Christ IS God. It also states that Christ (The Word) was WITH God. That speaks of "God the Father."
John 16:7 states: "Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you." This speaks of God the Holy Spirit. Therefore, by showing the differences between the three "entities" (The Trinity) we can accept that there are three. We cannot point to ONE particular Scripture verse that states we MUST believe in the Trinity. Everyone has their own analogies to represent the Trinity. However, as we look at different verses we can see that there are three distinct entities, yet, there is ONLY one God divided into three different beings, but, they still remain ONE. We must accept this, in faith. No, one analogy can possibly represent the obvious. John 1:14 states: "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."
As we recall John 1:1 Stated: "In the beginning was the Word, and the Word was with God, and the Word was God." Therefore, we know that the WORD is Christ and He was with God the Father and He (Christ) was God. So, when we place it all together: God the Son became flesh, while, God the Father and God the Holy Spirit remained in Heaven. In conclusion, Christ IS part of the Diety. He is God as is The Father and The Holy Spirit. Jesus in the Garden of Gethsemane prayed to God the Father. He wasn't praying to Himself. Right before Christ was to be crucified, He told His Disciples that He would send God The Holy Spirit.
The Bible shows us there are THREE different entities, however, states, there is ONLY one God. To my knowledge, there is no verse of Scripture that states that we MUST have a full understanding of the Trinity to become a member of the Body of Christ, however, we must accept that Christ was/is part of the Godhead.
