Faith in Christ pertains to the inner content of the life of Christ. It is not just a collection of religious ideologies and moralisms which ignore Christ and His message in order to return to bondage to the law, as if we were without Grace.
It is said by the Saviour that "not one jot or tittle of the law shall pass away until all things be fulfilled." How is it that anyone (even Orthodox clergy) turn to this saying, yet never, ever pay heed to the prayer we say at the Proskomedia, just after the prayer before the Amvon, and before the final blessing? It begins with the theological statement, "Thou who art Thyself the fulfillment of the Law and the Prophets ..."
If Christ Jesus did not "fulfill all things," what did He accomplish?
Of course, if you believe in the 'Atonement' heresy--that Christ was tortured to death to satisfy the bloodlust of a cruel and unforgiving deity, and died to save us from God--then you might not realize that Christ did indeed, fulfill all things so that every jot and tittle of the law may pass away, so that the "manuscript that was against us is torn up," as Paul says, and the "middle wall" (Eph. 2:14) is broken down.
