Ambrose of Milan
Catena Aurea · Lukasevangelium 11
But he, knowing their thoughts, said unto them, Every kingdom divided against itself is brought to desolation; and a house divided against a house falleth. If Satan also be divided against himself, how shall his kingdom stand? because ye say that I cast out devils through Beelzebub. And if I by Beelzebub cast out devils, by whom do your sons cast them out? therefore shall they be your judges. But if I with the finger of God cast out devils, no doubt the kingdom of God is come upon you.
At the same time He shews that it is a regal power which the Holy Spirit possesses, in whom is the kingdom of God, and that we in whom the Spirit dwells are a royal house.
