The Trinity is the teaching of one God in three persons: Father, Son, and Holy Spirit.  Each is distinct from the other, but each is divine and of one substance.  They are all the one God, not three gods.  This is the proper and orthodox doctrine of the Christian church. A triad is three separate gods.  The biblical Trinity is not a triad. They are different and both cannot be true at the same time.

The Jehovah’s Witnesses deny the Trinity and repeatedly misrepresent it by saying it is a triad of three gods.  They have been corrected countless times but continue to often misrepresent it. The Mormons also deny the Trinity and teach a triad of Gods. They teach that there is a god called Elohim who is supposed to be the Father. He has a literal body of flesh and bones because he’s an exalted man from another world. He is married and has physical relations with his goddess wife to produce spirit offspring in the preexistence. The second god is Jesus – who is the literal brother of the devil and all of us. The third god is the Holy Ghost.  In Mormonism, the three gods comprise the Godhead, a triad of three separate gods.

So, the proper and true doctrine of the Bible and Christianity is that the Trinity is one God in three persons, not a triad of three separate gods.
