The Shepherd And The Hireling

Mercenarius autem, et qui non est pastor, cujus non sunt oves propria... Quia eos non amat, sed lucrum, pro quo servit. De hoc Gregorius: Mercenarius est, qui locum quidem pastoris tenet, sed lucra anmarum non quaerit, terrenis commodis inhiat, honore praelationis gaudet, temporalibus lucris pascitur, impensa sibi ab hominibus reverentia laetatur, de qui potest dici illud Matth sexto: Amen dico vobis, receperunt mercedem suam. Hic scilicet vides lupum venientem, et dimittit oves, et fugit, quia lupum timet, et oves non amat. 4 Lupus, ut dicit Gregrious, super oves venit, cum quilibet injustus et raptor fideles et humilies opprimit. De talibus lupis Acts vigesimo: Scio, inquit Paulus, quoniam intrabunt post discenssionem meam lupi rapaces in vos, non parcentes gregi. Ad adventum talis lupi mercenarius dimittit oves. Zachar undecimo: O pastor, et idolum, derelinquens gregem. Ad hujus mercenarii fugam sequitur ovium dispersio, et ideo dicitur: Et lupus rapit, et dispergit oves. Ezechiel trigesimo quarto: Super omnem faciem terrae dispersi sunt greges mei, et non erat qui requireret. Sanctus Bonaventura, Commentarius In Evangelium Ioannem, Caput X Source: Here, p839

For the hireling is not the shepherd, the sheep are not his... 1 Because he does not love them but he serves for money. Concerning which Gregory says: 'He is a hireling who holds the place of the shepherd but does not seek the profit of souls. He coverts the rewards of the world, he rejoices in the honour of office, he feasts on temporal wealth, he delights to exert himself for the reverence of men.' 2 Of whom Matthew says: 'Truly I say to you, they have received their reward.' 3 He sees the wolf approaching and he abandons the flock, and he flees, because he fears the wolf and he does not love the sheep. The wolf, as Gregory says, 'comes upon the sheep, when any unjust robber oppresses the faithful and the humble.' 2 Concerning such wolves it says in Acts: 'I know,' says Paul, 'that ravening wolves will come among you after my departure, not sparing the flock.' 4 At the coming of the wolf the hireling abandons the sheep. Zachariah: 'O shepherd, O idol, forsaking the flock' 5 And with the flight of the hireling the scattering of the sheep follows, and therefore it is said: 'And the wolf seizes and the sheep are scattered.' 1 Ezekiel: 'Over all the face of the earth my flocks were scattered, and there was no one to seek them.' 6 Saint Bonaventura, Commentary On The Gospel Of Saint John, Chapter 10 1 Jn 10.12 2 Greg Evang Hom 14 3 Mt 6.2 4 Acts 20.29 5 Zach 11.17 6 Ezek 34.6
