God will never teach one concept and later contradict Himself. In the Old Testament, God reveals His teaching method and declares precept must be upon precept, precept upon precept: line upon line, line upon line, here a little and there a little... In other words, what God reveals as truth to Moses will not be shown to be error by Isaiah. What God reveals to Isaiah will not be shown to be error by Paul.
The most important teaching of the Old Testament is the revelation: God is one God, and we should love Him with all of our heart. The poor Trinitarian prophets have a hopeless time finding verses in the Old Testament to question the oneness of God. God declared in Isaiah 43:11, “I, even I, am the Lord, and beside me there is no Savior.”
Trinitarian prophets attempt to find support from the four verses in which God uses the plural pronoun “us” as evidence; however, the thousand verses wherein God uses the pronoun I cast a shadow over them like a mighty mountain.
The three-god people love Genesis 1:26, “And God said, let us make man in our image...” But their argument is defeated in the next verse, “God created man in His own image...” We know one cannot go from a plural pronoun to a singular pronoun if both have the same antecedent. Let us continue.
Moses declared in Deuteronomy 6:4, “Hear, O Israel, the Lord our God is one Lord: and thou shalt love the Lord thy God with all thine heart, and with all thy soul, and with all thy might.” The worship of multiple gods has always been the earmark of error and false worship, and it still is. Trinitarianism is not simply a different shade of Christianity. It is, rather, gross error and a false message that belittles our Lord Jesus Christ, the great Creator of heaven and earth.
Jesus proclaimed in the Gospel of John that He alone is the great “I Am” who was before Abraham. Jesus also said in John 8:24, “I said therefore unto you, that ye shall die in your sins: for if ye believe not that I am he, ye shall die in your sins.” In other words, if Jesus Christ is not the one and only God, and Trinitarians have another god, they are in trouble.
If their father in heaven is that old man with the long white beard, somewhere beyond the starry sky, they are worshiping according to the Greek concept of multiple gods, with one chief god whose name is Father (Zeus).
I wish Trinitarian prophets would stay away from Jewish people. No one with a foundation in the Old Testament can accept a gospel which declares God is a multitude of persons.
The battle line is drawn between the prophets of the Trinity and God's servants in Matthew 28:19. Jesus said, “Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost.” Peter declared the name in Acts 2:38, “Repent and be baptized in the name of Jesus Christ...” Not one time was anyone ever baptized in the titles, Father, Son, and Holy Ghost. Not one time!
