Fan Casting Nun-Too-Holy in Sort by Tropes

She's a nun, at least that's what it says on her job resume. However, she acts nothing like what she's claiming to be. Instead, she can be violent, destructive, steal from the collection plate, wear revealing clothing, be perverted like the best of them, forget all about her chastity vows, take God's name in vain, swear so much she'd make a sailor cry, and watch PG-13 movies. On top of this, she seems to have ideas or notions that directly contradict the Church she belongs to. In other words, she's anything but the normal image of a member of the Church you'd expect. It leads one to wonder how she managed to land this job in the first place.
