 The parish priest found that, on the high altar of his ruined church, was a sacrarium containing three consecrated hosts, which not only had been unharmed by the fire, but now were spotted with blood.Bishop Dietrich came to consecrate the hosts so as to ensure that no unconsecrated host was accidentally being venerated idolatrously, but, so the story goes, the host overflowed with blood before he could say the words of consecration.Miracles were soon attributed to the Holy Blood of Wilsnack, which soon became one of the most important places of pilgrimage in Europe, exceeding even Santiago, Rome and Jerusalem for numbers of pilgrims.
