Justification by Faith (Not Works) - the Lord's Supper as Our Sacrifice - Subjective Celebration of the Lord's Supper - Chrysostom

But why do I speak of fasting and the observance of special days? Paul continued to observe the Law and to endure many a toil; he patiently put up with many journeys and hardships; he surpassed all his contemporaries in the exact observance of that way of life. But after he achieved the heights of that life and came to realize that he was doing all this for his own hurt and destruction, he immediately changed. He did not say to himself: "What is this? Am I to lose the reward for this great zeal of mine? Am I to waste all this work?" Rather he was the quicker to change for the very reason that he might continue to suffer that loss. He scorned justification by the Law so that he might receive the justification of faith. And so he loudly proclaimed: "The things that were gain to me I have counted as loss for Christ." And Christ said: "If you offer your gift at the altar, and there you remember that your brother has anything against you, go first and be reconciled to your brother and then come and offer your gift." What do you mean? If your brother has something against you, Christ does not permit you to offer your sacrifice until you are reconciled to your brother. When you have the whole Church and so many Fathers against you, do you have the hardihood to dare to approach the divine mysteries before you put aside that unseemly enmity? Since this is the way you feel, how could you celebrate the Pasch? Fathers of the Church, St. John Chrysostom, Discourses Against Judaizing Christians, translated by Paul W.
