John Chrysostom

“For it was superfluous to say, ‘Thou art the son of Jona’; but as He had spoken of the Son of God, in order to show that as Peter is the son of Jona so He is the Son of God, of the same substance as the Begetter, He added further: _And I say to thee thou art Peter, and upon this rock I will build My Church_—that is, on the faith of this confession.”
