Footnotes
σπλάγχνα (splanchna) literally means "intestines" or "bowels"—the visceral organs were understood in both Jewish and Greco-Roman thought as the physical seat of the deepest emotions, equivalent to what we mean by "the heart" but far more raw and physical. Paul uses this word three times in Philemon (vv. 7, 12, 20), creating an emotional thread through the letter. F.O.G. preserves the visceral physicality with "inward parts"; F.O.G.M. renders it as "hearts" for emotional clarity—but both versions feel the gut-level weight Paul intended.
