Roman Catholic Blog has pictures from the Halloween Mass at the "Catholic-Christian community" of Corpus Christi in Aliso Viejo, in the Diocese of Orange, California. The pictures includes a devil in the choir(rock group) and a She-Devil as a extraordinary minister of Holy Communion. I guess someone dressed as a She-Devil giving out communion is extraordinary. Someone should have gone dressed as a kneeler, since in that diocese it would be pretty scary.
Catholic Church Conservation has pictures of a group of nuns (thankfully not at Mass) who appear to be willing to wear anything but a habit. Diogenes also comments on one of the pictures of a nun in solidarity with the murder of innocents – chickens that is.
