Our nation is being devastated by a great spiritual tsunami of lustful passions.  As Fr. Demetrios Carellas writes in the Introduction: “May this Canon to St. Mary, and the Spirit-filled prayers at the end, help us in our efforts to keep our souls from sinking under this soul-destroying tsunami.  May we also offer it as an intercession for others who are under the control of this demonic weapon of mass destruction, and who—at present—do not have the desire, or strength, to escape its terrible impact on their souls.”  Includes a prayer against internet pornography.

What is a Canon?  A canon is a structured hymn used in a number of Orthodox services. It consists of nine odes, sometimes called canticles or songs depending on the translation, based on compositions (also called odes) found in the Bible and, with one exception, the Old Testament.  (Source:  https://orthodoxwiki.org/Canon_(hymn))
