Cyrill of Alexandria
Let the Pharisee respond to me: who transformed their staffs into serpents? Why did they fail to present a pure hand that was leprous, and instead simply declare, 'This is the finger of God'? Pray tell, why did the priests of Baal fail to summon fire from the sky while Elijah succeeded (1 Kings 18:24, 14, 38)? Is God jesting? Certainly not. He is just and cherishes the righteous, wielding miraculous powers through the saints rather than through those who are sinful.
