A Flock Needs A Shepherd

Letter 1,18 - to Sub-deacon Peter. January 591.

"If some cities in the province of Sicily are known to be without the rule of a priest, through the loss of priests because of misdemeanors, see if someone can be found worthy of a priestly position. Inquire first of all into the gravity of their morals, and then send them over to us, as the flock of every single place ought not to be found destitute for a long time, due to a pastor's lapse.
But if, in fact, you will find some positions vacant, but nobody from that same church is discovered suitable for such an honor, report back to us after a similarly thorough inquire, so that God can decide whom he judges worthy of such ordinations.
For it should not happen that, through one person's deviation, the Lord's flock may be scattered through rugged places without a shepherd. For in this way, proper order results for the parishes, and no suspicion will remain for those who have lapsed of reverting to there former state, so that they are more rightly penitent."
