Wisdom of the Fathers

“For to free people from a demon is not so great as to rescue them from sin. It is not demons that prevent one from attaining to the kingdom of heaven. On the contrary, they assist, albeit unwillingly, by making him who has the demon more sensible. Sin, on the other hand, expels him” – Chrysostom on Acts 19:15 in Ancient Christian Commentary on Scripture: New Testament V: Acts, 238.
