John 14:9

τοσούτῳ χρόνῳ. Philip had been called among the first (John 1:44), and yet has not learned to know the Christ. Comp. John 8:19. The Gospels are full of evidence of how little the Apostles understood of the life which they were allowed to share: and the candour with which this is confessed confirms our trust in the narratives. Not until Pentecost were their minds fully enlightened. Comp. John 10:6; John 12:16; Matthew 15:16; Matthew 16:8; Mark 9:32; Luke 9:45; Luke 18:34; Luke 24:25; Acts 1:6; Hebrews 5:12. Christ’s question is asked in sorrowful but affectionate surprise; hence the tender repetition of the name. Had S. Philip recognised Christ, he would have seen the revelation of God in Him, and would never have asked for a vision of God such as was granted to Moses. See notes on John 12:44-45. There is no reference to the Transfiguration, of which S. Philip had not yet been told; Matthew 17:9. For the dative, a doubtful reading, see Winer, p. 273.

ὁ ἑωρακὼς ἐμὲ ἑωρ. τ. πατέρα. Again there is the majesty of Divinity in the utterance. What mere man would dare to say, ‘He that hath seen me hath seen God’? Comp. John 14:30; John 8:29; John 8:42; John 15:10.
