Jamieson, Fausset & Brown

Give none offence--in things indifferent (Co1 8:13; Rom 14:13; Co2 6:3); for in all essential things affecting Christian doctrine and practice, even in the smallest detail, we must not swerve from principle, whatever offense may be the result (Co1 1:23). Giving offense is unnecessary, if our own spirit cause it; necessary, if it be caused by the truth.
