Romans 14:15

15.But if through meat thy brother is grieved, etc. He now explains how the offending of our brethren may vitiate the use of good things. And the first thing is, — that love is violated, when our brother is made to grieve by what is so trifling; for it is contrary to love to occasion grief to any one. The next thing is, — that when the weak conscience is wounded, the price of Christ’s blood is wasted; for the most abject brother has been redeemed by the blood of Christ: it is then a heinous crime to destroy him by gratifying the stomach; and we must be basely given up to our own lusts, if we prefer meat, a worthless thing, to Christ. (428) The third reason is, — that since the liberty attained for us by Christ is a blessing, we ought to take care, lest it should be evil spoken of by men and justly blamed, which is the case, when we unseasonably use God’s gifts. These reasons then ought to influence us, lest by using our liberty, we thoughtlessly cause offenses. (429)
