St. John’s story of Holy Week has important differences to the tale told by the authors of the other Gospels, and its stories are perhaps a little less familiar to people, especially if they aren’t regular Bible readers.
One incident not recorded in the other Gospels is that of the visitors to Jerusalem who wanted to see Jesus. These were Greeks, in town to worship at the Passover festival, who approached Philip to seek an audience with the preacher who had so recently electrified the city. Philip and Andrew went to tell Jesus about them, and at this point the Greeks disappear from the story. We do not know whether they ever got to see Christ.
Instead, John retells Jesus replying with a discourse clearly alluding to the coming agony of Good Friday – “unless a grain of wheat falls into the ground and dies, it remains that and nothing more; but if it dies, it bears a rich harvest.” Why respond in such a curiously sideward way? Perhaps, this a case of Jesus, the King of Kings and Son of David, the culmination of the ethnocentric religion of Israel, dying to give life to a harvest of believers from all nations. And here is the soil in which that harvest will begin to ripen, citizens of the multi-ethnic Roman Empire already drawn to worship of the God of Abraham and Isaac even before the establishment of Christianity.
