Terminology Tuesday: Holiness
That quality of God and of things and persons set apart for God that marks whatever possesses it as “different” and “other” than the ordinary things of creation. Thus, when Moses met God at the burning bush, he was afraid and was told to remove his sandals, because the place was holy. In the New Testament, holiness increasingly took on the characteristics of righteousness and moral purity. The Holiness Movement is made up of those churches, especially in the Wesleyan tradition, that put a special emphasis on sanctification as a distinct work of grace. See also morality.
