On the Incomprehensible Nature of God
John Chrysostom · c. 347 – 407
Twelve sermons preached at Antioch against Eunomians who claimed to know God's essence. Chrysostom points at the seraphim, who cover their faces, and asks what a man is doing measuring what angels will not look at directly — then closes each sermon by begging his congregation not to leave before the prayers.
