And there was there a herd of many swine feeding on the mountain: and they besought him that he would allow them to enter into them. And he allowed them.
All Commentaries on Luke 8:32 Go To Luke 8
George Leo Haydock
AD 1849
If, says St. Athanasius, the infernal spirits have no power over such impure beasts as swine, with much greater reason then are they deprived of power over man, who is made after God's own image, and redeemed by the blood of his son, Christ Jesus. We should therefore fear only God, and despise the devil. (Life of St. Anthony)
