“Sometime later he was wearing himself out by severe fasting and abstinence, pushing himself day and night with vigils and prayer. While he was celebrating Mass as customary in a certain crypt, a spider fell into the already consecrated chalice.[6-2] When the priest saw it he was shocked. Life and death hovered before his eyes. The spider was large. What should the man do whose faith[6-3] was now deeply rooted in the Lord? Lest the sacrifice suffer any loss he chose rather to undergo the danger and consumed whatever was in the chalice.
When the sacrifice was finished he expected to die immediately. While he remained at his place before the altar he commended his awaited end to the Lord in prayer. When he was disturbed by an itching in his nose he scratched it and suddenly he sneezed expelling the whole spider. Once again God did not want the death[6-4] but the faith of his priest who he knew would be useful to him.”
