Peter of Damaskos

A man must first submit to the law of God, and then he will rule as an intelligent being over all around him. His intellect will reign as it was originally created to reign, with judgment and self-restraint, with courage and justice. Now he will calm his wrath with the gentleness of his desire, now quieten his desire with the austerity of his wrath; and he will know that he is a king.
