Jas 4, 11b-12 Who then are you to judge your neighbor?

(Jas 4, 11b-12) Who then are you to judge your neighbor?

[11b] If you judge the law, you are not a doer of the law but a judge. [12] There is one lawgiver and judge who is able to save or to destroy. Who then are you to judge your neighbor?

(CCC 1961) God, our Creator and Redeemer, chose Israel for himself to be his people and revealed his Law to them, thus preparing for the coming of Christ. The Law of Moses expresses many truths naturally accessible to reason. These are stated and authenticated within the covenant of salvation. (CCC 1967) The Law of the Gospel "fulfills," refines, surpasses, and leads the Old Law to its perfection (Cf. Mt 5:17-19). In the Beatitudes, the New Law fulfills the divine promises by elevating and orienting them toward the "kingdom of heaven." It is addressed to those open to accepting this new hope with faith - the poor, the humble, the afflicted, the pure of heart, those persecuted on account of Christ - and so marks out the surprising ways of the Kingdom.(CCC 1968) The Law of the Gospel fulfills the commandments of the Law. The Lord's Sermon on the Mount, far from abolishing or devaluing the moral prescriptions of the Old Law, releases their hidden potential and has new demands arise from them: it reveals their entire divine and human truth. It does not add new external precepts, but proceeds to reform the heart, the root of human acts, where man chooses between the pure and the impure (Cf. Mt 15:18-19), where faith, hope, and charity are formed and with them the other virtues. The Gospel thus brings the Law to its fullness through imitation of the perfection of the heavenly Father, through forgiveness of enemies and prayer for persecutors, in emulation of the divine generosity (Cf. Mt 5:44,48).
