He beheld him not with His natural eye only, but by the insight of His Godhead discerned from eternity the simplicity and greatness of his soul, for which he was to be elevated above the whole Church. In the word Peter, we must not look for any additional meaning, as though it were of Hebrew or Syriac derivation; for the Greek and Latin word Peter, has the same meaning as Cephas; being in both languages derived from petra. He is called Peter on account of the firmness of his faith, in cleaving to that Rock, of which the Apostle speaks, And that Rock was Christ; (1 Cor. 10:4) which secures those who trust in it from the snares of the enemy, and dispenses streams of spiritual gifts.
