John 10:2

But he that entereth, &c. By the door S. Chrysostom understands the Holy Scriptures. "For these," he says, "lay open the knowledge of God, protect the sheep, drive away wolves, by precluding access to heretics." So also Theophylact, Leontius, and Euthymius. And also Theodorus of Heraclea (in Cat.), who gives also a further reason. "Scripture is the door, because he is a true pastor to whom the door gives ingress, that is on whom Scripture confers authority, and thus secures his acceptance." Other fathers regard Christ as the door, as He Himself says expressly. But you will say, Christ is the shepherd of the sheep, therefore He cannot be a door. For the shepherd enters by the door, therefore He cannot Himself be the door. S. Augustine replies; "The Lord Himself is the pastor and the door. He opens Himself who expounds Himself, and the porter is the Holy Spirit, of whom the Lord says, 'He will teach you all truth.' Christ therefore, who is the truth, is the door, and He who teacheth the truth openeth the door." And the Gloss says, "All who hold and teach the truth are one shepherd in Christ the Shepherd." Christ retained for Himself alone the name of door, for the sheep to enter in to God. But the shepherd entereth the door. For Christ Himself and other preachers preach Christ. But you may say more simply with Maldonatus, that Christ the shepherd enters by the door, i.e., by Himself, into the Church, because He enters by His own authority, but others by authority derived from Him. But it is not possible in a parable to make all expressions fit in exactly. Moreover, Syrians and Hebrews delight in parables, heaping them up one on another, and running them into each other. As Christ in this place mixes up the similes of the door and the shepherd. Ver. 3. To him the porter openeth. (1.) That is Moses, as bearing testimony to Christ, says S. Chrysostom and others. (See chap. v. 46.) (2.) S. Cyril thinks that it means the angel who presides over the whole Church (S. Michael, as is supposed). (3.) The genuine meaning (according to S. Augustine, Chrysostom, and many others) is, that it means the Holy Ghost, "for the Scriptures opened by Him point out Christ as the Shepherd," says Theophylact. Or rather the Holy Ghost opened a door for Christ into the Church, when He constituted Him the Pastor of the Church, confirmed His authority by His testimony, His grace, and miracles, as when He descended on Him in the form of a dove at His baptism, and afterwards through Him gave sight to the blind, healed the sick, and raised the dead. And He also places over the Church all other Pastors whatsoever, the lawful successors of Christ, and causes them to be acknowledged and accepted, and by them brings in all the other faithful into the Church. He also exposes the frauds of heretics, and causes them to be expelled from the Church.

And the sheep hear his voice. Just as sheep when they hear the call of the shepherd, so do Christian people acknowledge the true pastor (and those whom He substitutes as His deputies), listen to His voice, and follow Him in all things. S. Augustine, and Bede after him, understand by the sheep only the predestinated, for they are called sheep, and are distinguished from the goats (Mat 23:33). But this relates to the judgment when the elect and saved are separated from the reprobate. But the present passage relates to the Church militant, where the elect are mingled with the reprobate, and cannot be separated. Both then are called sheep. The sheep then are all the faithful. For they are all of them in the Church, and acknowledge, love, and worship Christ as their Shepherd.

And calleth His own sheep by name, i.e., one by one. For the shepherd looks after them singly, and calls them, both in a body and separately, to follow Him to the pasture. And if any of them be sick He takes it out by itself, gives remedies, and if necessary carries it on His shoulders. Moreover, skilful shepherds commonly give names to their sheep and other animals, and call to them by their names. And in like manner Christ and every pastor give names to Christians at their baptism, and call them by them. He also takes care of them one by one, so as to feed them by His example and the Holy Sacraments, and thus leads them to salvation and heavenly glory.

Leontius observes that Christ here sets forth eight signs and duties of a true pastor; that he enters by the door, that the Porter opens to him, that he can address his sheep by their several names, that he leads forth his sheep, that he goes before them, that his sheep follow him, and that he lays down his life for the sheep. Such was S. Chrysostom, who, speaking on his banishment, thus addresses his people (Hom. xi.), "Ye are my father, ye are my mother, ye are my life, ye are my grace. If ye make progress, I am delighted. Ye are my crown, my riches, my treasure. I am prepared to be offered a thousand times for you; nor need you thank me for this. I am only discharging a debt. For a good pastor ought to lay down his life for his sheep. For to such an one death brings immortal life."

And leads them forth to the pastures, which are not without, but within the fold, that is in the Church itself. For in the Church the pastor teaches the people, celebrates Mass, baptizes, administers the Sacraments, &c. Besides, the Church is the assembly of the faithful, and therefore where the faithful are there also is the Church, or a part thereof Ver. 4. And when he leadeth forth his sheep (to the pastures) he goeth before them, to lead the way, to defend them from the wolf and the spoiler, and to lead those that follow him by a direct and convenient road to better pastures. And so in like manner Christ and every true pastor (1.) go before the faithful in their way to heaven by the example of a holy life. Let a pastor therefore consider that he ought to be the leader and guide of the faithful in sanctity, to surpass them all, to give to all a bright pattern of virtues, so that looking on him, they may follow him to greater heights, as S. Peter says (1 Epist. chap. v. 3). (2.) A pastor by his vigilance and energy protects the faithful from heretics, scandals, and other evils. (3.) He points out the straight way to heaven, and feeds and nurtures them with the best advice he can.

Anagogically. St Augustine says, He who went before the sheep is He who being raised from the dead, dieth no more, and who said to the Father, "I will that they also whom Thou hast given Me, be with Me where I am." (Joh 17:24)

And the sheep follow him, for they know his voice. They distinguish his voice from that of others, and therefore follow it. Ver. 5. But a stranger will they not follow, for they know not the voice of strangers, i.e., of heretics, Jews, heathens, and all wicked and deceitful men, for the genuine sheep of Christ fly from them as from wolves.
