Are the laws of the Old Testament still valid today?

The Orthodox nuance

Christ says that He did not come to abolish the Law, but to fulfill it. Fulfillment does not mean simply preserving every old form, but bringing them to their full meaning. Passover, sacrifices, the Temple, priesthood, purifications — all point to Christ.

This is why the Church does not oblige Christians to circumcision, Jewish dietary laws, or Israel's civil penalties. The apostolic council in Acts 15 clearly shows that the nations enter the Church without first becoming Jews according to the old Law.

Yet the Old Testament does not become useless. It teaches us God's holiness, the gravity of sin, the pedagogy of the commandments, and the expectation of Christ. The Christian reads it in the Church, not as an ancient penal code to apply directly, but as Scripture fulfilled in the Lord.
