Romans 12:5 states: "So we, being many, are one body in Christ, and every one members one of another."
I Corinthians 12:12: "For as the body is one, and hath many members, and all the members of that one body, being many, are on body: so also is Christ.
I Corinthians 10:17: "For we being many are one bread, and one body; for we are all partakers of that one bread."
No, I am not trying to say the saints of the body of Christ are on the same level as God. But, I have demonstrated that something can be both plural and singular at the same time. The body of Christ (The Church) is an entity made of individuals who posses the same nature (e.g. although I like dogs and cats, scripture does not support a dog or cat becoming part of the body of Christ. They don't possess humanity and therefore cannot become part of the body of Christ).
Now, God the Father; God the Son, and God the Holy Ghost, all possess the same divine eternal nature, yet they are uniquely united as one and always in harmony in [their] purpose. And, there is distinctness of personhood within the God of the Bible. And here is proof:
Matthew 23:41-44 (Jesus references Psalms 110:1)
While the Pharisees were gathered together, Jesus asked them, Saying, "What think ye of Christ? whose son is he?" they say unto him, "the son of David" He saith unto them, "How then doth David in spirit call him Lord, saying, 'The Lord said unto my Lord, Sit thou on my right hand, till I make thine enemies thy footstool?'
From these words out of Jesus' own mouth you must either believe that there is more than one distinct person in the God of the Bible, or you must believe that Jesus was telling himself, to sit on the righthand of himself, till he made the enemies of himself, the footstool of the self which was sitting on the righthand of himself; or something like that - I could accept this sort of talk if it was what Jesus meant; But, this is not what Jesus meant.
Not convinced. Okay, let's look at St. John 14:12: "Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also: and greater works than these shall he do: because I go unto my Father." Again, we have words from the lips of Jesus. You must believe that there is more than one distinct person in the God of the Bible, or you must believe Jesus speaking in that place and time to his disciples was talking about going unto himself - as in Jesus was somewhere else and right there talking with his disciples and he [Jesus] would need to go unto this place where his same self was.
Next passage: John 14:16 & 17a "And I will pray the Father, and he shall give you another Comforter, that he may abide with you forever; Even the Spirit of truth;" We have here Jesus speaking, and he "will pray the Father." As you may, know the New Testament was originally written in Greek. Actually, the word "pray" as used in the verse above, is translated from the Greek word <erotao>. This word means to ask, beseech, desire, intreat, pray. Further this Comforter who is the Spirit of truth is the Holy Ghost. So if we add to the belief that the son and Father are the same person, and the son and the Holy Ghost are the same person. This passage of scripture could be paraphrased as: Jesus was going to beseech/or ask himself if he himself, could send himself to be the Comforter.
But you may say Jesus is only speaking metaphorically or symbolically. That would be twisting the scriptures and taking them out of context. Well, let me give one more scripture passage which absolutely cannot be misconstrued to be metaphorical (or a figure of speech):
