Romans 14:21

It is good The word is in antithesis to the "it is evil" just before. The "strong" Christian might deem his own exercise of liberty good per se;and his "weak" brother's obedience to scruples evil per se. The Apostle shews him that the exact contrary might be the case. Not the principleof liberty, but its application, might be positively mischievous, and the practical "breach" of the theory might be its truest "honour."

For a still stronger expression of the noble principle of this verse, see 1 Corinthians 8:12. Never did that principle more need to be remembered than at the present day.

offended Here, of course, as throughout this passage, the word bears its antiquated meaning "is made to stumble."

is made weak In his obedience to the sense of duty.
