The Trinity revisited.

Does the trinity doctrine come from eastern religions like Hinduism? Did the Catholic church appropriate this doctrine from the eastern pagan religions and just slap the persons of the Father and The Son and the made up person of the holy ghost onto this very ancient superstition and false teaching which tries to keep you out of the family of Yahweh. Read John 17 the whole chapter and see how it couldn't possibly add up to 3 but a much higher number of which you should be a part. You must repent, change keep Yahweh's word and have a tranformed life and accept Yahshua the Messiah as your Saviour. Yahweh wants us to be part of His family. He didn't limit it to three.
