John 1:42

Verse 42. Cephas. This is a Syriac word, meaning the same as the Greek word Peter, a stone. Mt 16:17. The stone, or rock, is a symbol of firmness and steadiness of character--a trait in Peter's character after the ascension of Jesus that was very remarkable. Before the death of Jesus he was rash, headlong, variable; and it is one proof of the omniscience of Jesus that he saw that Peter would possess a character that would be expressed appropriately by the word stone or rock. The word Jonas is a Hebrew word, whose original signification is a dove. It may be that Jesus had respect to that when he gave Simon the name Peter. "You now bear a name emblematic of timidity and inconstancy. You shall be called by a name denoting firmness and constancy."

(k) "thou shalt be called Cephas" Mt 16:18 (7) "A Stone" or, "Peter"

John 21:16-17

Verse 16. Feed my sheep. The word here rendered feed, as has been remarked, is different from the word in the previous verse. It has the sense of governing, caring for, guiding, protecting --the kind of faithful vigilance which a shepherd uses to guide his flock, and to make provision against their wants and dangers. It may be implied here that the care needed for the young in the church is to instruct them, and for those in advanced years both to instruct and govern them.

My sheep. This term commonly denotes the church in general, without respect to age, John, chapter 10.

(k) "Feed my sheep" Heb 13:20, 1Pet 2:25
Verse 17. The third time. It is probable that Jesus proposed this question three times because Peter had thrice denied him. Thus he tenderly admonished him of his fault and reminded him of his sin, while he solemnly charged him to be faithful and vigilant in the discharge of the duties of the pastoral office. The reason why the Saviour addressed Peter in this manner was doubtless because he had just denied him--had given a most melancholy instance of the instability and weakness of his faith, and of his liability to fall. As he had thus been prominent in forsaking him, he took this occasion to give to him a special charge, and to secure his future obedience. Hence he so administered the charge as to remind him of his fault; and he made him so prominent as to show the solicitude of the Saviour that henceforward he might not be left to dishonour his high calling. This same charge, in substance, he had on other occasions given to the apostles (Mt 18:18), and there is not the slightest evidence here that Christ intended, as the Papists pretend, to give Peter any peculiar primacy or eminence in the church. The charge to Peter arose, manifestly, from his prominent and melancholy act in denying him, and was the kind and tender means used by a faithful Saviour to keep him from similar acts in the future dangers and trials of life. It is worthy of remark that the admonition was effectual. Henceforward Peter was one of the most firm and unwavering of all the apostles, and thus fully justified the appellation of a rock, which the Saviour by anticipation had given him. Jn 1:42.
