I believe in the trinity.. one triune God.
The Father, Son and Holy Spirit as one being.
I do have an issue with seperating them out into seperate beings.. because there are too many verses when they are interchanging roles or doing the same thing at the same time.
I believe when I get to heaven I will meet God... full stop. One being. I don believe I'll meet Jesus.. the Father.. and the Holy Spirit as seperate beings.. because that would be pretty much Polytheism.
But.. as long as people believe the Father, Son and Holy Spirit are equally God.. no inferiority from one to the other.. I got no beef.. because then it is just semantics.
I believe there is only one God and that God is the Father "Have we not all one father? hath not one God created us?..."-(Malachi 2:10) If Jesus is God it logically fallows that Jesus is the Father. Want more prove "For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace."-(Isaiah 9:6) Jesus is the Son prophesied about and there is only ONE Father. More prove Jesus Himself taught that He was the Father. "Then said they unto him, Where is thy Father? Jesus answered, Ye neither know me, nor my Father: if ye had known me, ye should have known my Father also."-(John 8:19). "I said therefore unto you, that ye shall die in your sins: for if ye believe not that I am he, ye shall die in your sins."-(John 8:24). More prove we should note that "he" in the verse is in italics, which indicates that it is not in the original Greek, been added by the translators. Jesus was really identifying Himself with the "I AM" of (Exodus 3:14). The Jews who did not understand his meaning, asked, "Who art thou?" Jesus answered, "Even the same that I said unto you from the beginning."-(John 8:25). However "They understood not that he spake to them of the Father."-(John 8:27). In other words, Jesus tried to tell them that He is the Father and the I AM and that if they did not accept Him as God they would die in their sins.
In 1 John 5:7 the Father, the Word which is the Son (John 1:14), and the Holy Spirit is simply God, God is Holy (Leviticus 11:44; 1 Peter 1:16) God alone is holy in Himself. God is also a spirit (John 4:24), and there is only one spirit of God (1 Corinthians 12:11; Ephesians 4:4). Therefore "Holy Spirit" is another term for the ONE God. therefore 1 John 5:7 the Father, the Word, and the Holy Spirit bear record in heaven and that these three are titles of the one (Jesus Christ)
The same way they saw Jesus descend into heaven is the saw way we will see Him come back. One God not two or three like you said that would be polytheism.
