γάγγραινα

From the study of 2 Timothy 2:17

Range of meaning

A technical medical word, probably related to γράω (graō, 'to gnaw, eat'). It names an eating, spreading ulcer: a sore whose tissue is dying and which keeps advancing into the healthy flesh around it. Ancient doctors also distinguished it from σφάκελος (sphakelos), the stage where a limb or area is completely dead. So gangraina was the active, still-spreading phase, which is exactly why it was so frightening.

Against the English

Most modern versions say 'gangrene', which is accurate. The KJV's 'canker' and the Latin Vulgate's 'cancer' were also accurate in their day, since both words then meant a spreading, eating sore. Today 'canker' suggests a minor mouth ulcer or a disease of trees. 'Cancer' is closer in feel, but it brings in the modern idea of a tumour.

How it drifted

English 'canker' (from Latin cancer, 'crab; spreading ulcer') used to mean any corroding, eating sore. Over time its everyday meaning shrank to the small, harmless 'canker sore', so the KJV now sounds far milder than Paul's image.

Used elsewhere in the period

The word is common in Greek medical writing: the Hippocratic corpus, and later Galen, who describes gangraina as the stage just before total necrosis (tissue death). It also appears in Plutarch's moral writings, which use disease imagery for spreading vices. It occurs nowhere else in the New Testament or the Septuagint.
