The Vatican Gendarmerie intervened and led the perpetrator away after a few minutes.
According to the Vatican Press Office, this was a “sad event that deeply wounded the feelings of the faithful in a year dedicated to hope.”
After viewing the recording of the incident, Pope Leo XIV expressed his concern about what had happened “in the heart of the Church.” He therefore ordered that a penitential ceremony be held as soon as possible as a sign of repentance and a request for forgiveness for the desecration of the altar.
The ceremony finally took place on Monday, October 13, at 12 noon, in the presence of Cardinal Mauro Gambetti, the archpriest of the basilica, and several bishops. He followed the prescription of the Ceremoniale Episcoporum (No. 1070), which states that “if acts are committed in a church that seriously violate the sanctity of the place, no more services may be celebrated there until the offense has been atoned for by a penitential ceremony.”
