“Heretic” is one of those words we struggle to use well. Often times, you see it used in one of two ways—either liberally or ironically. One equates all disagreement with apostasy, the other pretends disagreement doesn’t matter at all.
Both rob the word of its power.
Justin Holcomb understands the seriousness of heresy and what it means to call someone a heretic—it is “a weighty charge that [is] not made lightly, nor [is] it used whenever there [is] theological inaccuracy or impression” (14).
So how do we learn to use this word wisely? By knowing what heresy really is. And so, we have Holcomb’s newly released Know the Heretics. This short book introduces readers to several heresies that have threatened the church throughout history, and how the controversies surrounding each—whether it be the requirement to obey the Law, the existence of original sin, or the Trinity itself—helped shape the church as it is today.
