Theophylact of Ohrid — as excerpted in the Catena Aurea on Mark 9:14-29

“(ap. Pseudo-Hier.) Again, when Jesus, that is, the word of the Gospel, takes hold of the hand, that is, of our powers of action, then shall we be freed from the devil. And observe that God first helps us, then it is required of us that we do good; for which reason it is said that Jesus raised him, in which is shewn the aid of God, and that he arose, in which is declared the zeal of man.”
