APOSTASY (ecclesiastical)

One of the three kinds of desertion recognized by the laws of the Roman Catholic Church; from Christianity, when a baptized person entirely gives up his Christian faith; from orders, when a cleric abandons the ecclesiastical state; and from religion, when a man or woman leaves the religious life without dispensation from public vows.
