By St. John of Damascus
We have, then, adequately demonstrated that there is a God, and that His essence is incomprehensible. But that God is one and not many is no matter of doubt to those who believe in the Holy Scriptures.
For the Lord says in the beginning of the Law: "I am the Lord your God, which have brought you out of the land of Egypt. You shall have no other gods before Me" (Exodus 20:2-3).
And again He says, "Hear, O Israel, the Lord our God is one Lord" (Deuteronomy 6:4).
And in Isaiah the prophet we read, "For I am the first God and I am the last, and beside Me there is no God. Before Me there was not any God, nor after Me will there be any God, and beside Me there is no God" (Isaiah 43:10).
And the Lord, too, in the holy Gospels speaks these words to His Father, "And this is life eternal, that they may know You the only true God" (John 17:3).
