The Immaculate Conception and the East

Today for Latin Catholics is the feast of the Immaculate Conception. Here in the United States, it is the country's patronal feast. I take the liberty of directing you to the interview I did earlier this year with the priest and scholar Christiaan Kappes about his new book, The Immaculate Conception: Why Thomas Aquinas Denied, While John Duns Scotus, Gregory Palamas, & Mark Eugenicus Professed the Absolute Immaculate Existence of Mary.
