November 8, 1308 - John Duns Scotus Dies

The idea that Mary, the mother of Jesus, was also born through immaculate conception was first theorized by a Scottish theologian named John Duns Scotus. Scotus died on November 8, 1308, in Cologne Germany, but his theory remains prevalent in Roman Catholic theology. Pope Pius IX agreed with his theory and made the Immaculate Conception of Mary a central part of Roman Catholic teaching.
