12 When you sin against them in this way and wound their weak conscience, you sin against Christ.

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

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

12 And when you sin against other believers by encouraging them to do something they believe is wrong, you are sinning against Christ.

12 But when you thus sin against the brethren, and wound their weak conscience, you sin against Christ.

12 When you sin against your brothers and sisters in Christ like this and cause them to do what they feel is wrong, you are also sinning against Christ.

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

12 Now, thus sinning against the brethren, and wounding their weak conscience, ye sin against Christ.

12 When you sin against other believers in this way and harm their weak consciences, you are sinning against Christ. 

12 Now when you sin like this against the brothers and wound their weak conscience, you are sinning against Christ.

12 But when you thus sin against members of your family, and wound their conscience when it is weak, you sin against Christ.

12 Now if you sin in this way against the brothers and wound their conscience, which is weak, you sin against Christ.

12 When you sin against other believers in that way, you harm their weak sense of what is right and wrong. By doing that you sin against Christ.
