During the Easter Mass in the church of San Giovanni, a man who was receiving communion responded to the traditional formula "the Body of Christ" by saying "thanks" and then asking "what part of the body is this?" and began walking away, carrying the consecrated host and denouncing the Catholic religion. Parishioners were shocked and one ordered the man to consume the host before leaving the building.
