Are you sure? Most Christians today would say that believing the 3 in 1 God idea is essential to being a Christian. That is a 5th century doctrine that comes from the Athanasian Creed. The idea comes from the Creed, not Scripture.We don’t base our doctrinal belief upon creeds.
Jesus Christ is YHWH, the Lord God Almighty; Creator of heaven and earth. He is the only begotten Son of God.
He is equal to God the Father, but as any Son submits to their Father to honor them, so it is with the Son of God.
Let this mind be in you which was also in Christ Jesus, who, being in the form of God, did not consider it robbery to be equal with God,
Again going back to what I said about the OP. Logic dictates that there cannot be multiple almighties. Only one can be almighty. If the ultimate power is shared by multiple beings then none is almighty because they don't have power over the others. Webster defines almighty as having complete power. If Jesus and the Fsther are equal neither has power over the other, thus neither has complete power.
