"No, we are not bound to keep them all, except those relevant today. In Jesus, a new covenant was made (1 Cor 11 :25) and we are the new people of God bound by the new law of love (Jn. 13:34) But this new law is not altogether new (1 Jn 2:7) it is the fulfilment of the old law. Indeed Jesus came to fulfil the law and present it in its pristine purity. He advocated for unconditional and unlimited forgiveness (Mt. 18: 21-22) and was against even the just retaliation (Mt. 5:38-42) allowed by the old despensations (Ex. 21: 23-25). He upheld the unity of the marriage bond (Mt 9:5-10) against its liberal interpretation by the rabbis. He put reconciliation among men, a precondition for man's reconciliation with God (Mt. 12: 1-8; 5: 23-24). Though circumcision was asserted by the O.T. it was abolished by the Gospel (Gul. 5:1-4; Eph. 2:11, 15. However the spiritual significance of Circumcision (Deut 10:16; Jer 4:4) is not overlooked by the NT. Paul also speaks of a circumcision of heart (Rom 2:29), by which a christian is reborn to the new life in Christ (Phil 3:3; Cor. 2:11; Gal. 6:15). However, Jerusalem Council dispensed the gentile Christians from the law of physical circumcision (Acts 15:6-29). Though Jesus observed Sabbath on Saturday as any other Jew does, we Christians observe on Sunday, since is the Lord's day, the day of his resurrection.
In short we are not to be slaves of any stipulations (2 Cor 5:17). We have to interpret them taking into consideration the compulsion of Christian doctrines (love) and the visicitudes of our human existence.
