John 14:9

hast thou not known me Or, hast not recognised Me, as in John 14:7. 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.
