Fulgentius of Ruspe

In his own words on Exodus

• Exodus 3:14

  Hold most firmly and never doubt that the holy Trinity, the only true God, just as it is eternal, is likewise the only one by nature unchangeable. He indicates this when he says to his servant Moses, "I am which I am."

  TO PETER ON THE FAITH 9.50

• Exodus 20:2

  In the first commandment of the Decalogue, just as the worship and service of the one Lord God is most clearly commanded, so for adoration and service to be shown by the faithful to any creature is most vehemently forbidden. For it is said there: "I am the Lord your God, who brought you out of the land of Egypt, out of the house of slavery; you shall have no other gods before me." If this is taken as spoken simultaneously by the Father and the Son, the Father and the Son are believed to be one Lord God. But if either the Father is believed to have said this without the Son or the Son without the Father, it is necessary that the Father or the Son be denied to be the Lord God. Concerning this he said, "I am the Lord your God who brought you out of the land of Egypt, out of the house of slavery; you shall have no other gods before me."
