1 Corinthians 8:12

But when ye sin so against the brethren: sin is properly against God, for it is a breach of the Divine law; but the violations of that part of the Divine law which concerneth our duty to our neighbour, are called sins against our brethren, that is, sins against God in matters which concern our duty towards our brethren. And wound their weak conscience; the giving the weak judgments of others, by your examples, an occasion of sin, by venturing upon actions which they think sinful, is that which is here called a beating, or a wounding, their weak consciences, because it is indeed a hurting and defiling of them. Ye sin against Christ; this the apostle determineth to be a sinning against Christ; both against the law of Christ, concerning loving one another, and against the love of Christ, who, in dying for the weakest believers, hath showed the highest degree of love imaginable to them; whom they are far from following, who will not abate themselves a small matter of liberty, where the use of it this or that way may very probably be an occasion of sin and ruin to their brethren's souls.
