Usage

What does apostatize mean? Apostatize means to totally abandon or reject one’s religion. It can also be used in a slightly more general way to mean to totally abandon or reject one’s principles, cause, party, or other organization. The act of doing so is called apostasy, and someone who does so can be called an apostate. These words typically imply that before the rejection, one had a strong connection or involvement. They are all usually used in a way that’s critical of such abandonment—or that at least implies that others who remain in the religion or cause are critical of the departure. Apostasy is sometimes used more specifically to refer to a rejection of Christianity, but apostasy and apostatize are also used in the context of other religions, such as Islam. Example: The pastor’s sermon condemned those who apostatize—the trouble is, the apostates weren’t there to hear it.

Etymology

Origin of apostatize

From the Late Latin word apostatīzāre, dating back to 1545–55. See apostate, -ize

Explanation

To apostatize is to give up a belief. Your best friend may do her best to sway you to change your basketball allegiance from the Celtics to the Lakers, but you refuse to apostatize. When someone renounces their religious principles, leaving one faith for another or ceasing to believe at all, they apostatize. The Latin root, apostata, means "one who forsakes religion or faith." This is the most common way to use this verb, but it also works well for changes in political belief: "I never thought he'd apostatize, but he's now a registered Democrat."
