Hilary of Poitiers
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.
By asking, Whom do men say that the Son of Man is? He implied that something ought to be thought respecting Him beyond what appeared, for He was the Son of Man. And in thus enquiring after men’s opinion respecting Himself, we are not to think that He made confession of Himself; for that which He asked for was something concealed, to which the faith of believers ought to extend itself. We must hold that form of confession, that we so mention the Son of God as not to forget the Son of Man, for the one without the other offers us no hope of salvation; and therefore He said emphatically, Whom do men say that the Son of Man is?
