Apostolic Constitutions, Book II 20
1As to a good shepherd, let the lay person honour him, love him, reverence him as his lord, as his master, as the high priest of God, as a teacher of piety. For he that hears him, hears Christ; and he that rejects him, rejects Christ; and he who does not receive Christ, does not receive His God and Father: for, says He, He that hears you, hears me; and he that rejects you, rejects me; and he that rejects me, rejects Him that sent me. In like manner, let the bishop love the laity as his children, fostering and cherishing them with affectionate diligence; as eggs, in order to the hatching of young ones; or as young ones, taking them in his arms, to the rearing them into birds: admonishing all men; reproving all who stand in need of reproof; reproving, that is, but not striking; beating them down to make them ashamed, but not overthrowing them; warning them in order to their conversion: chiding them in order to their reformation and better course of life; watching the strong, that is, keeping him firm in the faith who is already strong; feeding the people peaceably; strengthening the weak, that is, confirming with exhortation that which is tempted; healing that which is sick, that is, curing by instruction that which is weak in the faith through doubtfulness of mind; binding up that which is broken, that is, binding up by comfortable admonitions that which is gone astray, or wounded, bruised, or broken by their sins, and put out of the way; leasing it of its offenses, and giving hope: by this means restore it in strength to the Church, bringing it back into the flock. Bring again that which is driven away, that is, do not permit that which is in its sins, and is cast out by way of punishment, to continue excluded; but receiving it, and bringing it back, restore it to the flock, that is, to the people of the undefiled Church. Seek for that which is lost, that is, do not suffer that which desponds of its salvation, by reason of the multitude of its offenses, utterly to perish. Search for that which is grown sleepy, drowsy, and sluggish, and that which is unmindful of its own life, through the depth of its sleep, and which is at a great distance from its own flock, so as to be in danger of falling among the wolves, and being devoured by them. Bring it back by admonition, exhort it to be watchful; and insinuate hope, not permitting it to say that which was said by some: Our impieties are upon us, and we pine away in them; how shall we then live? As far as possible, therefore, let the bishop make the offense his own, and say to the sinner, Do thou but return, and I will undertake to suffer death for you, as our Lord suffered death for me, and for all men. For the good shepherd lays down his life for the sheep; but he that is an hireling, and not the shepherd, whose own the sheep are not, sees the wolf coming, that is, the devil, and he leaves the sheep, and flees, and the wolf seizes upon them. We must know, therefore, that God is very merciful to those who have offended, and has promised repentance with an oath. But he who has offended, and is unacquainted with this promise of God concerning repentance, and does not understand His long-suffering and forbearance, and besides is ignorant of the Holy Scriptures, which proclaim repentance, inasmuch as he has never learned them from you, perishes through his folly. But — like a compassionate shepherd, and a diligent feeder of the flock — search out, and keep an account of your flock. Seek that which is wanting; as the Lord God our gracious Father has sent His own Son, the good Shepherd and Saviour, our Master Jesus, and has commanded Him to leave the ninety-nine upon the mountains, and to go in search after that which was lost, and when He had found it, to take it upon His shoulders, and to carry it into the flock, rejoicing that He had found that which was lost. In like manner, be obedient, O bishop, and seek that which was lost, guide that which has wandered out of the right way, bring back that which is gone astray: for you have authority to bring them back, and to deliver those that are broken-hearted by remission. For by you does our Saviour say to him who is discouraged under the sense of his sins, Your sins are forgiven you: your faith has saved you; go in peace. But this peace and haven of tranquillity is the Church of Christ, into which do you, when you have loosed them from their sins, restore them, as being now sound and unblameable, of good hope, diligent, laborious in good works. As a skilful and compassionate physician, heal all such as have wandered in the ways of sin; for they that are whole have no need of a physician, but they that are sick. For the Son of man came to save and to seek that which was lost. Since you are therefore a physician of the Lord's Church, provide remedies suitable to every patient's case. Cure them, heal them by all means possible; restore them sound to the Church. Feed the flock, not with insolence and contempt, as lording it over them, but as a gentle shepherd, gathering the lambs into your bosom, and gently leading those which are with young.
