9 Time forbids me to survey the period which has passed since the Lord's ascension, or to recount the bishops, the martyrs, the divines, who have come to Jerusalem from a feeling that their devotion and knowledge would be incomplete and their virtue without the finishing touch, unless they adored Christ in the very spot where the gospel first flashed from the gibbet. If a famous orator blames a man for having learned Greek at Lilybæum instead of at Athens, and Latin in Sicily instead of at Rome (on the ground, obviously, that each province has its own characteristics), can we suppose a Christian's education complete who has not visited the Christian Athens?
