Having come this far, this blessed father brings his commentary to rest at the point of 'finding a corner-stone.' This can be understood also of the only-begotten Son of God, who was made flesh for our sakes, according to the word in the Psalms: 'The stone which the builders rejected'—the teachers of the Jews—'this has become the head of the corner.' For by the good pleasure of the Father he came upon the earth and joined together in himself the two peoples, both of the Jews and of the Gentiles, just as, indeed, the corner-stone also binds together both walls.
