Ezekiel 34:4

It is the abbot's responsibility to have great concern and to act with all speed, discernment and diligence in order not to lose any of the sheep entrusted to him. He should realize that he has undertaken care of the sick, not tyranny over the …

And since it is incumbent on us who seem to be in charge and in the place of shepherds to guard the flock, if we should be found negligent, what will be said to us was said to our predecessors who were such negligent leaders.

Do you see a shepherd's vigilance? Do you see his heightened interest? What excuse could they have to whom rational flocks are entrusted but who are guilty of great negligence and day after day, in the prophet's words, slaughter some of them and look on without intending to take any care of others made the prey of wild beasts or the spoils of other people—even when the labor involved is slight and attention easy? It is a soul, after all, that is to be instructed; but that involves much labor for body and soul.

Having therefore mentioned the marks of a shepherd, Christ hath put two kinds of spoilers; one, the thief who kills and steals; the other, one who doth not these things, but who when they are done doth not give heed nor hinder them. By the first, pointing to Theudas and those like him; by the second, exposing the teachers of the Jews, who neither cared for nor thought about the sheep entrusted to them. On which account Ezekiel of old rebuked them, and said, "Woe, ye shepherds of Israel! Do the shepherds feed themselves? Do not the shepherds feed the sheep?" But they did the contrary, which is the worst kind of wickedness, and the cause of all the rest. Wherefore It saith, "They have not turned back the strayed, nor sought the lost, nor bound up the broken, nor healed the sick, because they fed themselves and not the sheep."... From both Christ distinguisheth Himself; from those who came to spoil, by saying, "I am come that they might have life, and that they might have more abundantly"; and from those who cared not for the sheep being carried away by wolves, by never deserting them, but even laying down His life for them, that the sheep might not perish.

If we scorn the repentance of those who have in some degree the assurance of a bearable conscience, immediately they are drawn by the devil's invitation into heresy or schism with their wife and children, whom they had kept unharmed. And it will be charged against us on judgment day that we have not cared for the wounded sheep and have lost many innocent ones because of one wounded.

For one who had been cast away is brought back, when any one who has fallen into sin is recalled to a state of righteousness by the vigour of pastoral solicitude. For ligature binds a fracture when discipline subdues a sin, lest the wound should bleed mortally for want of being compressed by the severity of constraint. But often a fracture is made worse, when it is bound together unwarily, so that the cut is more severely felt from being immoderately constrained by ligaments. Hence it is needful that when a wound of sin in subordinates is repressed by correction, even constraint should moderate itself with great carefulness, to the end that it may so exercise the rights of discipline against delinquents as to retain the bowels of loving-kindness.

The priests took no care to instruct the ignorant, to rectify the mistakes of those that were in error, to warn the unruly, or to comfort the feeble-minded. The ministers of state took no care to check the growing distempers of the kingdom, which threatened the vitals of it. Things were amiss, and out of course, every where, and nothing was done to rectify them.

The diseased have ye not strengthened,....

The diseased have ye not strengthened - No person is fit for the office of a shepherd, who does not well understand the diseases to which sheep are incident, and the mode of cure. And is any man fit for the pastoral office, or to be a shepherd of souls, who is not well acquainted with the disease of sin in all its varieties, and the remedy for this disease, and the proper mode of administering it, in those various cases? He who does not know Jesus Christ as his own Savior, never can recommend him to others.
