Lenski on the Yoke of the Law in Acts 15:10

"Christ’s removal of the yoke of the law made circumcision and kosher eating, etc., no longer obligatory in any sense apart even from the matter of gaining salvation ; yet neither were these Jewish practices and modes of living forbidden by Christ. They became adiaphora, matters of liberty and choice, that should not be forced upon others or become a cause of pride and marks of special holiness as compared with Gentile Christians, Peter could continue kosher eating, for instance, but not as though that elevated him above those who did not eat kosher and made him stand higher in God's sight."
