The majority of Orthodox Christians do not accept the Scholastic definition of Mary's preservation from original sin before her birth as subsequently defined in the Western Church after the Great Schism of 1054. After the feast was translated to the Western Church in the 8th century, it began to be celebrated on December 8. It spread from the Byzantine area of Southern Italy to Normandy during the period of Norman dominance over southern Italy. From there it spread to England, France, Germany, and eventually Rome.
