He defines how the good shepherd must be recognized. Fighting for the salvation of the flock, he must give even his own life without hesitation. This was fulfilled by Christ.
The father of sin, according to what is said in the Psalms, set us to be shepherded "like sheep in Hades," Ps 48:15, by handing us over to death. But the truly good Shepherd died for us, so that, drawing us out of the dark abysses of death, He might make it possible for us to be numbered among the heavenly choirs. Instead of folds in the abysses of the deep and depths of the sea, He granted us the dwellings above with the Father.
Therefore He says to us in one place: "Fear not, little flock, for it is your Father's good pleasure to give you the Kingdom," Lk 12:32.
But this concerns Christ. Now let us consider them. To everyone who judges them with a faithful eye, they will in fact appear to be nothing other than hirelings, false shepherds, cowards, traitors, and idlers. They pay no attention at all to the benefit of the sheep, but strive only to obtain from every side what is pleasant and agreeable to each.
Yes, they were "hirelings," according to the Savior's word, and the sheep were "not their own." They belonged to Christ, who purchased them from the beginning and ordained hierarchs over the Jewish people for heavenly honors.
But they neglected such great honors and did not value the fold of the flock at all. They handed the sheep over to the wolf. We shall say briefly how this happened.
In ancient times the numerous Jewish people acknowledged only God as king. To Him they gave didrachmas and sacrifices. As though offering a kind of tribute, they brought a life in accordance with the law.
But a foreign man, or people, came upon this people like a wild "wolf." He imposed both the name and the reality of slavery, placed upon them the yoke of human kingship, compelled them to pass into a lawless and immoral life, demanded tribute, and tore them away from the Kingdom of God. Those who fell into such calamities were compelled to submit to the laws of their masters.
The foreigner came, thrusting aside the authority of God, that is, the tribe which had received the sacred ministry, to which judgment and law had been entrusted by God. He distorted everything, imposed constraint, compelled his own image to be struck on the coins, and carried out every kind of violence.
Yet against such unbearable oppression the shepherds did not keep watch. They saw "the wolf coming" and, leaving the flock, fled, because the sheep were not "their own." They did not call upon Him who could help, who had saved them from the Babylonians, turned away the Assyrian, and slain by the hand of an Angel "one hundred eighty-five thousand" foreigners, Is 37:36.
That subjection to the authority of foreigners brought no small harm to Israel and weakened piety, you can learn from the facts themselves. When Pilate once rebuked the incredible insolence of the Jews, who demanded that he crucify the Lord, and said plainly, "Shall I crucify your King?" Jn 19:15, they then cast off slavery to God and broke the bonds of the original dominion. They subjected themselves to a new yoke and shamelessly cried out: "We have no king but Caesar," Jn 19:15.
The rulers of the Jews thought it just to do and proclaim this. Therefore the blame for all the calamities must be placed upon them. With every justice they are condemned as traitors of the flock, as cowards deprived of courage, and as foolish men who utterly refused to defend and fight for the flock subject to them.
Therefore God accuses them in these words: "The shepherds have become senseless and have not sought the Lord. Therefore the whole flock did not understand and was scattered," Jer 10:21.
Thus the facts themselves prove that Christ is the truly good Shepherd of the sheep. They, however, are destructive rather than good, and altogether alien to true praise.
Man fell away from the love of God, turned aside into sin, and for this was removed from the holy and divine court, that is, from the enclosure of Paradise. Having suffered such calamity, he became the prey of the devil, who enticed him to sin and to death born from sin, those fierce and untamed wolves.
But when Christ, the good Shepherd over all, appeared, He laid down His life for us, fighting against this pack of fierce beasts. He endured the Cross for us, so that by death He might put death to death. He underwent condemnation for our sake, to free all from condemnation for transgression. By faith He abolished the sin that held dominion, "nailing to His Cross the handwriting that was against us," as it is written, Col 2:14.
