Does Strict Monotheism disagree with Trinitarianism, why or why not?

Question

References, please.

Answer 1

"Jews are taught that God is One, God is Indivisible, and this is found throughout the Hebrew Scriptures. Isaiah 44:6 tell us that, "I am the first, and I am the last; and beside me there is no God." When Isaiah tells us that God said, "I am the first," it means that God has no father. When Isaiah tells us that God said, "I am the last," it means that God has no literal son. And when Isaiah tells us that God said, "Besides me there is no God," it means that God does not share being God with any other god, or demi-god, or semi-god, or persons."

Answer 2

Strict Monotheism disagrees with what you refer to as "Trinitarainism" (the idea of a 'Holy Trinity').

This was actually the theological debate behind Arianism centuries ago. The debate was whether or not God was absolute or if Jesus was 'God material' (part of God or made by God).....

Monotheism; One God.... thats it.... Jesus is not God or even part of God..... forget about the Holy Spirit.... too many 'deities.

Trinitarianism; Holy Trinity.... three-in-one deity
