I believe in the Father Yahweh and in His only begotten Son Yahshua. People have learned to accept the logic of the trinity blindly but it is only a man-made philosophy designed and instituted by the Catholic Church 300 years after the resurrection. In John 3:38, Yahshua shows us clearly that He is not the Father - "For I came down from heaven, NOT TO DO MINE OWN WILL, but, the will of Him that sent Me." That's not a magic formula unless you want the trinity to be true. Taking it for what it says, the Father and the Son are two very different persons. The Son came to show us that it is possible to bend your own will to the Father's will.
Many try to say that Yahshua said He was in the Father and the Father in Him, so that made them the same person, and thus both God. If you use that logic, then John 15:4 which says, "Abide in Me, and I in you", would be saying we are god - but in all honesty, we are, because He says in John 10:34-35 that the law says we are gods and Yahweh said we were gods.
The real problem is using the word 'god' as a blanket. God is really an anglo-saxon word for 'good'. The whole idea of using blanket words came from the priests of Yisrael telling the people of Yisrael, it was illegal to speak the sacred name YHWH or Yahweh. They hid the Father's name by making it so sacred and holy, no one was allowed to utter it. Look what Yahshua told us He came to do.
