William Burkitt on 1 Corinthians 8:12

The apostle goes on to show, that such an use of our Christian liberty as doth embolden and encourage others to do that which is evil, is both an act of uncharitableness towards our brother, and also an act of sin against our Lord Jesus Christ, in betraying a soul to ruin as much as in us lieth, and hindering his salvation, for the saving of whom Christ died; wounding the members of his body, defeating the great end of his death, and destroying them whom he designed to save.

Learn, 1. That Christ, in dying for the weakest believers, hath shown the highest degree of love imaginable unto them.

Learn, 2. That such as will not abate or abridge themselves of their Christian liberty, when the use of it may probably be an occasion of sin, and the ruin of their brethren's souls, do at once wound their weak brethren, and sin against Christ.
