Gregory the Great, on John 10:11

“I am the good shepherd. The good shepherd giveth his life for his sheep.”

“(Hom. in Evang. xiv.) The wolf too cometh upon the sheep, whenever any spoiler and unjust person oppresses the humble believers. And he who seems to be shepherd, but leaves the sheep and flees, is he who dares not to resist his violence, from fear of danger to himself. He flees not by changing place, but by withholding consolation from his flock. The hireling is inflamed with no zeal against this injustice. He only looks to outward comforts, and overlooks the internal suffering of his flock. The hireling fleeth, because he is an hireling, and careth not for the sheep. The only reason that the hireling fleeth, is because he is an hireling; as if to say, He cannot stand at the approach of danger, who doth not love the sheep that he is set over, but seeketh earthly gain. Such an one dares not face danger, for fear he should lose what he so much loves.”
