Thanks for admitting that many moslems have made up lies about 3 Gods in Christianity. Even an islamist like you admit no such Bible verse about 3 Gods in Christianity.
If you know a priest who say 3 Gods in Christianity, tell them your same reply from sammyboy that there's no such verse in the Bible that support the "3 God's" claim.
As for what the Trinity is, remember that fake prophet mahomet thought that the Trinity is God the Father, Mary the Mother and Jesus their love son.
