sacrilege

n. desecration of the holy, profanation of the sacred

Sacrilege is the violation or injurious treatment of a sacred object. In a less proper sense, any transgression against the virtue of religion would be a sacrilege. It can come in the form of irreverence to sacred persons, places, and things. When the sacrilegious offense is verbal, it is called blasphemy.
