I recall having to call the police in during a Mass when I was a sacristan although it wasn’t during a Solemnity. It was a wedding Mass. I man in a drunken stupor had entered the main entrance of the Church and spread out laying on a pew near the entrance atrium. I would have been satisfied to leave him there because he was so wasted he fell fast asleep.
Had not the enterage of the brides family not been very visibly upset I had no choice but to call the police. Given the fact most of the congregation seated hardly noticed the frucas; the police arrived with two officers and escorted the gentlemen with no disturbance given his stupor state.
Given the geographic location of my parish being in the downtown core in back of the city hall with nightclubs, bars and pubs everywhere we get this thing sometimes. Most times the Ushers can handle it with little disturbance and risk. Usually weddings take place Friday’s early evening and Saturday mornings before 12 noon. Daytime drunks can be a problem too but you deal with it in a civil manner.
