Word History of Anathema

The Greek root of anathema originally meant simply “a thing devoted” or “an offering,” and in the Old Testament it could refer to either revered objects or objects representing destruction brought about in the name of the Lord, such as the weapons of an enemy. Since the enemy’s objects therefore became symbols of what was reviled or unholy, the neutral meaning of “a thing devoted” became “a thing devoted to evil” or “curse.”

In Latin, it could refer to both an excommunication and the person who has been excommunicated.

In the early Church, anathema was used interchangeably with excommunication and to refer to unrepentant heretics. It then came to mean the severest form of excommunication in official church writings. When the authority of Rome was split in the Great Schism between Eastern and Western churches in 1054, an anathema was issued by Rome against the Eastern Patriarch who then issued another one against the cardinal who delivered it.
