Beginning from this scripture (arxameno apo th graph tauth). As a text. Philip needed no better opening than this Messianic passage in Isaiah. Preached unto him Jesus (euhggelisato autwi ton Ihsoun). Philip had no doubt about the Messianic meaning and he knew that Jesus was the Messiah. There are scholars who do not find Jesus in the Old Testament at all, but Jesus himself did ( Luke 24:27 ) as Philip does here. Scientific study of the Old Testament (historical research) misses its mark if it fails to find Christ the Center of all history. The knowledge of the individual prophet is not always clear, but after events throw a backward light that illumines it all ( 1 Peter 1:11 ; 2 Peter 1:19-21 ).
