so, "God said in genesis let US create man" who was he talking to?
and, the verse that said " everything was created through him" why didnt he say through me if they are one?
so coffee with cream means coffee is the same as cream??
Coffee and cream do not provide a good analogy for what Christians are saying when they talk about the Trinity. I can't be more clear than the Athanasian Creed.
I agree fully that the Trinity is paradoxical. Unfortunately, we as Christians must live with this tension because, like it or not, the bible makes the following claims:
1. There is only one divine being.
2. The Father is divine.
3. The Son is divine in the same sense that the Father is divine.
4. The Holy Spirit is divine in the same sense that the Father and the Son are divine.
5. The Father, Son, and Holy Spirit are distinct "persons." (Unfortunately, the church literally had to invent a concept here in order to get at what is going on, so the English word "person" is wholly inadequate. But it's what we've got. Sigh.)
So, the Church eventually settled on the idea that there is one divine substance/entity/being, but three distinct persons who "share" (is that the right word?) that divinity, which belongs to God alone. The theological concept that eventually developed was the trinity.
It's also well to note that this formulation arose as a result of intense controversy within the church. In the early centuries, the Church had to decide between three options: trinitarianism (what I've just described, championed by Athanasius), modalism -- the idea that there is one god who visits his people in three different modes or fashions, and Arianism -- the idea that there is only on god and therefore there is no possible sense in which Jesus could be anything more than a human. Indeed, Arianism was the more popular option, even beyond the Council of Nicea which decided in favor of trinitarianism. However, trinitarianism eventually won out for various reasons, including the fact that the position simply reflects best what scripture says.
So, here is a trinitarian interpretation of the sayings you present.
"God said in genesis let US create man" who was he talking to?
No matter how you look at it, this is a puzzle. If God is unitarian (not a trinity), we still have the question who he was addressing. A unitarian might say that he was addressing the angels. In fact, many do say that. Even many trinitarians say that. However, God says, let US. So is he suggesting that the angels get down to the business of creating people? Not likely, for God is the only creator. Thus the US must refer to the Triune God. Thus the persons of the trinity are addressing each other.
We should also keep in mind that this passage was written by highly unitarian Jews. In that case, what could the "us" possibly mean? Scholars have suggested that the "us" is similar to the "royal we." Royalty would often refer to themselves in the plural as a way of implying their magnificence and supremacy. It seems logical to think that God is speaking in that way here. In that case, God (whether trinitarian or not) is speaking of his own intentions. Who is he speaking to? Jews would hold that he was speaking to the "heavenly court" or the angels.
and, the verse that said " everything was created through him" why didnt he say through me if they are one?
Paul was speaking there, so of course he wouldn't say "through me". I assume you meant, "Why didn't he say through
them?" Well perhaps Paul was speaking of the Triune God, not picking out any of the persons. That would be legitimate, wouldn't it? It would be just as legitimate to say "through Jesus" or "through the Father" or "through the Holy Spirit." However, in the context of the verse, "him" refers to Jesus. Paul is arguing for the supremacy of Jesus in this passage. So to call out the Father or the Holy Spirit here would not be appropriate.
