bringing Eastern Orthodox and Roman Catholics Together

Welcome to the Website of the Orientale Lumen Foundation

Started in 1997 in Washington, DC, these ecumenical conferences are a “grass roots” movement among lay persons and clergy to provide a forum for Christians to learn about the “light from the east.”

They allow Eastern Orthodox, Eastern Catholics and Roman Catholics to meet and pray together, learn from each other’s traditions, and become friends together searching for a common goal: “that they all may be one” in the One Church of Christ.
