There is a St. Philomena parish in Torrance, CA. They wouldn’t have a parish named after her if she weren’t a saint.
I belong to a parish, St. Christopher’s in which at one time declared not a saint.
My wife is the Confirmation Director there. Very active Christ centered Parish. There are 450 teens in Confirmation year 1 and 2 classes. Maybe that’s a miracle whether Philomena is a Saint or not!
