While visiting the town of Walsingham, however, a procession of the Blessed Sacrament passed them by. Dunstan—who had shown no signs of religiosity for years—instinctively fell to his knees, bowed his head and made the sign of the Cross. Philip was stunned. “At that point, I thought I had lost Dunstan forever. But I soon realized that I’d actually been blessed, by seeing who Dunstan really was—and that revelation, in turn, enabled me to re-discover my own spiritual calling.”
