"According to the Catechism of the Catholic Church (§ 491-492), the Blessed Virgin Mary, the Mother of Jesus Christ our Savior, “was redeemed from the moment of her conception.” This teaching, which has a long history in the West but was unknown in Armenian circles, was not accepted as a Roman Catholic dogma until 1854, when Pope Pius IX issued an encyclical (Ineffabilis Deus) declaring that Mary “from the first moment of her conception…was by God’s grace and by virtue of the merits of Jesus Christ…immune from all stain of original sin.” In the Armenian tradition there is no mention of the Holy Virgin’s conception until the 14th century. It was during the late Cilician period that he Armenian Church fathers became aware of some of the questions about the Holy Virgin’s conception under discussion among the theologians of the Roman Catholic Church. The Feast of the Virgin’s Conception, which is now celebrated on December 9, was not introduced into the Armenian tradition until the 17th Century, and it was done so under Western influence."
