COVENANTER — [Noun] A person bound by a solemn agreement; historically, a member of the 17th-century Scottish Presbyterian movement pledged to defend their faith via the National Covenant and Solemn League and Covenant. From covenant (from Old French covenant, present participle of covenir, "to agree," from Latin convenire, "to come together, agree") + the agent noun suffix -er. Unlike a noncovenanter—a label of specific historical refusal—or a covenantist—a broader, less historically freighted designation—the term "covenanter" is irrevocably stamped by the solemn, public act of subscription. It is the scrape of a quill on vellum in a cold kirk, the grit of oatcake and psalm on a fugitive's tongue in the heather, and the specific, stubborn light in the eyes of a prisoner on the Bass Rock—a testament that some agreements are not transactions, but identities forged under the terrible gravity of a promise written in land and blood.
