Orthodox Apologetics

The one in the middle is the Father of the Universe, who in the Sacred Scriptures is called by his proper name, I am that I am ; and the Beings on each side are those most ancient Powers which are always close to the living God, one of which is called his Creative Power, and the other his Royal Power. And the Creative Power is God, for it is by this that he made and arranged the Universe; and the Royal Power is the Lord, for it is fitting that the Creator should lord it over and govern the creature.
