3.  Our Lord Jesus Christ erewhile became Man, but by the many He was unknown.  Wishing, therefore, to teach that which was not known, He called together His disciples, and asked them, Whom do men say that I, the Son of Man, am Matt. xiii. 16.? —not from vain-glory, but wishing to shew them the truth, lest dwelling with God, the Only-begotten of God Compare iv. 7:  “God of God begotten;” xiii. 3 and 13:  “God the Son of God.”  Here however, the mss. vary, and the reading of Cod. Coisl. Υἱῷ Θεοῦ μονογενεῖ is approved by the Benedictine Editor, though not adopted.  The confusion of Υἱῷ and Θεῷ is like that in John i. 18., they should think lightly of Him as if He were some mere man.  And when they answered that some said Elias, and some Jeremias, He said to them, They may be excused for not knowing, but ye, My Apostles, who in My name cleanse lepers, and cast out devils, and raise the dead, ought not to be ignorant of Him, through whom ye do these wondrous works.  And when they all became silent (for the matter was too high for man to learn), Peter, the foremost of the Apostles and chief herald ὁ πρωτοστάτης τῶν ᾽Αποστόλων καὶ τῆς ᾽Εκκλησίας κορυφαῖος κήρυξ.  Cf. ii. 19. of the Church, neither aided by cunning invention, nor persuaded by human reasoning, but enlightened in his mind from the Father, says to Him, Thou art the Christ, not only so, but the Son of the living God.  And there follows a blessing upon his speech (for in truth it was above man), and as a seal upon what he had said, that it was the Father who had revealed it to him.  For the Saviour says, Blessed art thou, Simon Barjona, for flesh and blood hath not revealed it to thee, but My Father which is in heaven Matt. xvi. 17..  He therefore who acknowledges our Lord Jesus Christ the Son of God, partakes of this blessedness; but he who denies the Son of God is a poor and miserable man.
