I was once asked to give a talk at Washington’s National Cathedral on prayer in the Eastern Orthodox tradition. I brought with me a large icon, one familiar to many people, showing the Holy Trinity as the three visitors who came to Abraham (Gen. 19:1-8); it was painted by St. Andrei Rublev in 1410. I set up the icon on an easel, but after saying a few words about it, focused on the Jesus Prayer. This simple, repetitive prayer—“Lord Jesus Christ, have mercy on me”— was developed by the Desert Fathers, as a help toward learning to “pray without ceasing” (1 Thess 5:17).
But when we re-gathered for a workshop later on, I found that the participants wanted to know more about the role of the icon. What is its function in prayer? What are the prayers used when looking at an icon?
