Sanctification

Sanctification is the act or process of acquiring sanctity, of being made or becoming holy. "Sanctity" is an ancient concept widespread among religions, a property of a thing or person sacred or set apart within the religion, from temple vessels to days of the week, to a human believer who achieves this state. To sanctify is literally "to set apart for special use or purpose," figuratively "to make holy or sacred," and etymologically from the Latin verb sanctificare which in turn is from sanctus "holy" and facere "to make."
