True God Yahweh? Only if your Judean, Israel's high God was EL. I don't believe Jesus was a Jew. No one knows Gods name, the creators name. Take your pick. The Christian religion is a trinity, do Jews or Muslims have a trinity , no, where do trinities come from, Rome, and Egypt also had some.
Catholicism councils created the trinity, at the first council of Nicea, no trinity was taught, it was added at a later council.
Jesus promised to keep making Gods name known( John 17:26)--the only way that can be done is through his one single true religion.
He also taught his followers that name-John 17:6
Jesus teaches he has a God like we do, his Father-John 20:17, Rev 3:12--so does Paul-2Cor 1:3, 1Cor 8:6, 1Cor 15:24-28--Peter at 1Peter 1:3--John at Rev 1:6
No the Christian religion is not a trinity--the great apostasy is a trinity(2Thess 2:3)--The religion Jesus started serves-YHWH(Jehovah) a single being God and accepts Jesus as the one sent forth from God-the Messiah.
