Besides this, the triple appealing of the Savior to Peter and the triple confession of Peter before the Lord had a particular beneficial purpose for the Apostle. That one, to whom was given "the keys of the kingdom" and the right "to bind and to loose," bound himself thrice by fear and cowardice (Mt.26:69-75), and the Lord thrice loosens him by His appeal and in turn by his confession of strong love. And to shepherd literally the flock of Christ was acquired by all the Apostles and their successors. "Take heed, therefore unto yourselves, and to all the flock," the Apostle Paul urges church presbyters, "over which the Holy Spirit hath made you overseers, to feed the Church of the God, which He hath purchased with His own blood" (Acts 20:28); and the Apostle Peter to the elders: "Feed the flock of God which is among you, taking the oversight thereof not by constraint, but willingly: not for filthy lucre, but of a ready mind: neither as being lords over God's heritage, but being examples to the flock. And when is appeared the Prince of pastors, ye will receive unfading crowns of glory" (1 Pet. 5:2-4).
It is remarkable that Christ, having said to Peter: "Feed My sheep," did not say: "Feed thy sheep," but rather to feed, good servant, the sheep of the Lord. "Is Christ divided? was Paul crucified for you? or were ye baptized in the name of Paul?" (1 Cor.1:13). "Feed My sheep". Wherefore "wolfish robbers, wolfish oppressors, deceitful teachers and mercenaries, not being concerned about the flock" (Mt.7:15; Acts 20:29; 2 Pet 2:1; John 10:12), having plundered a strange flock and making of the spoils as though it be of their own particular gain, they think that they feed their flock. Such are not good pastors, as pastors of the Lord. "The good shepherd giveth his life for the sheep" (John 10:11), entrusted to Him by the chief Shepherd Himself (1 Pet 5:4). And the Apostle Peter, true to his calling, gave his soul for the very flock of Christ, having sealed his apostleship by a martyr's death, is now glorified throughout all the world.
The Apostle Paul, formerly Saul, was changed from a robbing wolf into a meek lamb. Formerly he was an enemy of the Church, then is manifest as an Apostle. Formerly he stalked it, then preached it. Having received from the high priests the authority at large to throw all Christians in chains for execution, he was already on the way, he breathed out "threatenings and slaughter against the disciples of the Lord" (Acts 9:1), he thirsted for blood, but "He that dwells in the Heavens shall laugh him to scorn" (Ps 2:4). When he, "having persecuted and vexed" in such manner "the Church of God" (1Cor.15:9; Acts 8:5), he came near Damascus, and the Lord from Heaven called to him: "Saul, Saul, why persecutest thou Me?" and I am here, and I am there, I am everywhere: here is My head; there is My body. There becomes nothing of a surprise in this; we ourselves are members of the Body of Christ. "Saul, Saul, why persecutest thou Me; it is hard for thee to kick against the goad" (Acts 9:4-5). Saul, however, "trembling and frightened", cried out: "Who art Thou, Lord?" The Lord answered him, "I am Jesus Whom thou persecutest."
