The Crusades were served with a devotion that, had it been wise and true as it was fervent and undaunted, would have blessed the Eastern world. [...] The really important matter was not the possibility of pilgrimage but the obligation of witness. Christ's concern was, and is, for men not monuments, for souls, not sanctuaries.
