the trinity is a fraud doctrine without support in either testament.
in the OT Yahweh or Jehovah is the El Elohim, the God of [the gods] and the elohim are seen as beings of lesser power than him, but greater than humans
and often called angels or messengers when they come to earth. they are typically desginated as the beni-elohim or the sons of [the gods] meaning part of the guild of god like beings.
and the jews believed the "false" gods were rebel elohim. the world was created by ELOHIM = could mean all of them working as one, not just YHWH.
let US make man in OUR image is again spoken by the elohim. here the man has become like one of US is YHWH to the elohim.
gradually the jews came to see YHWH as the ONLY TRUE GOD, but to them this always included the rest of the faithful elohim as part of his total powerbase...and they were never included in the railings against the false gods.
trinitarians say god is three whos but one what...yet Isaiah clearly says YHWH is ONE person as well as ONE god...not three, no WE nor US, but I and HE.
the pick and chose out of context verses used to create the franken-god trinity from the new testament ignores a lot of contradictory verses which are quite clear.
