For ( γὰρ here certainly, rather than δὲ as in the Textus Receptus. It introduces a reason for the general admonition beginning at Romans 14:13) if on account of meat (not here, thy meat, as in the Authorized Version) thy brother is grieved, thou no longer walkest charitably (literally, according to love, or charity; i.
e. in continuing to set at naught his conscientious scruples). With thy meat destroy not him, for whom Christ died (cf. 1 Corinthians 8:11, καὶ ἀπολεῖται ὁ ἀσθενῶν ἀδελφὸς … δἰ ὃν χριστὸς ἀπέθανεν).
"Destroy" seems to denote causing his moral and religious ruin by shaking his conscientiousness, and perhaps upsetting altogether the faith he has, which, though weak, is real.
