Titus of Bostra
Catena Aurea · Lukasevangelium 11
And he was casting out a devil, and it was dumb. And it came to pass, when the devil was gone out, the dumb spake; and the people wondered. But some of them said, He casteth out devils through Beelzebub the chief of the devils. And others, tempting him, sought of him a sign from heaven.
(in Matt.) Now He calls the devil deaf or dumb, as being the cause of this calamity, that the Divine word should not be heard. For the devil, by taking away the quickness of human feeling, blunts the hearing of our soul. Christ therefore comes that He might cast out the devil, and that we might hear the word of truth. For He healed one that He might create a universal foretaste of man’s salvation. Hence it follows, And when he had cast out the devil, the dumb spake.
