*St. Ignatius (Brianchaninov)* not Antioch*
How does a person obtain this saving knowledge of himself, his “oldness,” a knowledge which opens to him the full, infinite significance of Christ’s Sacrifice? Here is how Saint Ignatius answers this question.
>I do not see my sin because I still labor for sin. Whoever delights in sin and allows himself to taste of it, even if only in his thoughts and sympathy of heart, cannot see his own sin. He can only see his own sin who renounces all friendship with sin; who has gone out to the gates of his house to guard them with bared sword—the word of God; who with this sword deflects and cuts off sin, in whatever form it might approach. God will grant a great gift to those who perform this great task of establishing enmity with sin; who violently tear mind, heart, and body away from it. This gift is the vision of one’s own sins (2:122). - St. Ignatius (Brianchaninov)
