"Holy Cow! You do believe that nonsense! You do believe that the Trinity only came into existence in 4 B.C.!!!!! You don't believe that the Trinity is eternal!! You don't believe that Jesus Christ is eternal!!!!"
You posted your reaction, but I don't see any explaination contained in the post. Jesus is the Father, because their Spirit is the same unique and identical Holy Spirit. John 10:30, " I and the Father are one." Before God created man, and man did have a beginning, God was not a trinity. Perhaps you don't understand what the word trinity means?
There it is again!
Who taught you this nonsense? Are you just making this stuff up or did you actually learn this stuff in Church?
No, God was always the Holy Trinity. The Fathers and the Ecumenical Councils speak of the Persons of the Trinity being co-eternal, of the begottenness of the Son and procession of the Spirit from the Father as being eternal.
You are skating very close to the formula of the condemned heretic Arius, 'there was when the Son was not'.
