IMMACULATE CONCEPTION Of Mary
On December 8, we honor Mary, our Mother on the Solemnity of the Immaculate Conception of the Blessed Virgin Mary (a Holy Day of Obligation). The doctrine states that "the Blessed Virgin Mary, in the first instance of her conception, was preserved exempt from all stain of original sin by a singular privilege and grace granted by God, in view of the merits of Jesus Christ, the Saviour of the human race."
