1 Corinthians 8:12

But when ye sin so against the brethren, and wound their weak conscience, ye sin against Christ.

Thus, sinning against the brothers, and wounding their conscience when it is weak, you sin against Christ.

And thus, sinning against the brethren, and wounding their conscience when it is weak, ye sin against Christ.

and thus sinning in regard to the brethren, and smiting their weak conscience -- in regard to Christ ye sin;

By sinning against your brothers in this way and wounding their weak conscience, you sin against Christ.
