Epistle — 1 Peter 1:1-7
Clement of Alexandria
On 1:3
"Blessed be the God and Father of our Lord Jesus Christ, who by His great mercy has regenerated us." For if God generated us of matter, He afterwards, by progress in life, regenerated us.
"The Father of our Lord, by the resurrection of Jesus Christ:" who, according to your faith, rises again in us; as, on the other hand, He dies in us, through the operation of our unbelief. For He said again, that the soul never returns a second time to the body in this life; and that which has become angelic does not become unrighteous or evil, so as not to have the opportunity of again sinning by the assumption of flesh; but that in the resurrection the soul returns to the body, and both are joined to one another according to their peculiar nature, adapting themselves, through the composition of each, by a kind of congruity like a building of stones.
On 1:6
And one aim and one end, as far as regards perfection, being demonstrated to belong to the man and the woman, Peter in his Epistle says, "Though now for a season, if need be, ye are in heaviness through manifold temptations; that the trial of your faith, being much more precious than that of gold which perisheth, though it be tried with fire, might be found unto praise, and honour, and glory at the revelation of Jesus Christ; whom, having not seen, ye love; in whom, though now ye see Him not, yet believing, ye rejoice with joy unspeakable, and full of glory, receiving the end of your faith, the salvation of your souls." Wherefore also Paul rejoices for Christ's sake that he was "in labours, more abundantly, in stripes above measure, in deaths oft."
Gospel — Matthew 16:13-19
Origen
On 16:13
Christ puts this question to His disciples, that from their answer we may learn that there were at that time among the Jews various opinions concerning Christ; and to the end that we should always investigate what opinion men may form of us; that if any ill be said of us, we may cut off the occasions of it; or if any good, we may multiply the occasions of it.
On 16:13
It must be enquired in this place whether, when they were first sent out, the disciples knew that He was the Christ. For this speech shews that Peter then first confessed Him to be the Son of the living God. And look whether you can solve a question of this sort, by saying that to believe Jesus to be the Christ is less than to know Him; and so suppose that when they were sent to preach they believed that Jesus was the Christ, and afterwards as they made progress they knew Him to be so. Or must we answer thus; That then the Apostles had the beginnings of a knowledge of Christ, and knew some little concerning Him; and that they made progress afterwards in the knowledge of Him, so that they were able to receive the knowledge of Christ revealed by the Father, as Peter, who is here blessed, not only for that he says, Thou art the Christ, but much more for that he adds, the Son of the living God.
On 16:13
See how great power has that rock upon which the Church is built, that its sentences are to continue firm as though God gave sentence by it.
On 16:14
Then the disciples recount the divers opinions of the Jews relating to Christ; And they said, Some say John the Baptist, following Herod’s opinion; others Elias, (vid. Matt. 14:2.) supposing either that Elias had gone through a second birth, or that having continued alive in the body, He had at this time appeared; others Jeremias, whom the Lord had ordained to be Prophet among the Gentiles, not understanding that Jeremias was a type of Christ; or one of the Prophets, in a like way, because of those things which God spoke to them through the Prophets, yet they were not fulfilled in them, but in Christ.
On 16:16
Peter denied that Jesus was any of those things which the Jews supposed, by his confession, Thou art the Christ, which the Jews were ignorant of; but he added what was more, the Son of the living God, (Ezek. 33:11.) who had said by his Prophets, I live, saith the Lord. And therefore was He called the living Lord, but in a more especial manner as being eminent above all that had life; for He alone has immortality, and is the fount of life, wherefore He is rightly called God the Father; for He is life as it were flowing out of a fountain, who said, I am the life. (John 14:6.)
On 16:18
But in heavenly things every spiritual sin is a gate of hell, to which are opposed the gates of righteousness.
On 16:18
He does not express what it is which they shall not prevail against, whether the rock on which He builds the Church, or the Church which He builds on the rock; but it is clear that neither against the rock nor against the Church will the gates of hell prevail.
On 16:18
Wherefore if we, by the revelation of our Father who is in heaven, shall confess that Jesus Christ is the Son of God, having also our conversation in heaven, to us also shall be said, Thou art Peter; for every one is a Rock who is an imitator of Christ. But against whomsoever the gates of hell prevail, he is neither to be called a rock upon which Christ builds His Church; neither a Church, or part of the Church, which Christ builds upon a rock.
On 16:19
Let him then be without blame who binds or looses another, that he may be found worthy to bind or loose in heaven. Moreover, to him who shall be able by his virtues to shut the gates of hell, are given in reward the keys of the kingdom of heaven. For every kind of virtue when any has begun to practise it, as it were opens itself before Him, the Lord, namely, opening it through His grace, so that the same virtue is found to be both the gate, and the key of the gate. But it may be that each virtue is itself the kingdom of heaven.
