Matthew 9:34

Verse 34. By the prince of the devils. What more foolish ever entered the mind of man. Is it possible, as he afterwards says, that devils should be expelled by devils? They assist and strengthen, not weaken and destroy one another. Moreover, he did not only cast out devils, but he cleansed the lepers, raised the dead, appeased the storm, forgave sins by his own power, preached the eternal felicity of heaven, and brought back man to God: all which the devil never could, never would bestow upon mankind. S. Chrysos. hom. xxxiii.
