Jerome
Catena Aurea · Matthäusevangelium 16
When Jesus came into the coasts of Cæsarea Philippi, he asked his disciples, saying, Whom do men say that I the Son of man am? And they said, Some say that thou art John the Baptist; some, Elias; and others, Jeremias, or one of the prophets. He saith unto them, But whom say ye that I am? And Simon Peter answered and said, Thou art the Christ, the Son of the living God. And Jesus answered and said unto him, Blessed art thou, Simon Barjona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven. And I say also unto thee, That thou art Peter, and upon this rock I will build my Church: and the gates of hell shall not prevail against it. And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven.
As much as to say, You have said to me, Thou art Christ, the Son of the living God, therefore I say unto thee, not in a mere speech, and that goes not on into operation; but I say unto thee, and for Me to speak is to make it sor, that thou art Peter. For as from Christ proceeded that light to the Apostles, whereby they were called the light of the world, and those other names which were imposed upon them by the Lord, so upon Simon who believed in Christ the Rock, He bestowed the name of Peter (Rock.)
