Understanding The Divine Nature Of God

God Is Not Like Us!

Is God a trinity, or is God one divine being? Christianity states that our Elohim is a trinity. Others state the idea of Oneness. Who is correct? I believe in the latter.
We shall break down this complicated relationship from the scriptures. No guess work needed.
Is Joseph the biological father of Yahushua like the camps teach, or is His biological Father our heavenly Father?
Is Yahushua also Father God Himself? Make it make sense.
