The Solemnity of the Immaculate Conception, December 8

On December 8, we honor Mary, our Mother. The Solemnity of the Immaculate Conception is a Catholic feast celebrating Mary's conception without sin. Even though this feast day occurs in the liturgical season of Advent, which prepares for the birth of Our Lord Jesus Christ, the Immaculate Conception refers to the conception of Mary in the womb of her mother, St. Anne.

The dogma of the Immaculate Conception asserts that, "from the first moment of her conception, the Blessed Virgin Mary was, by the singular grace and privilege of Almighty God, and in view of the merits of Jesus Christ, Savior of Mankind, kept free from all stain of original sin."

The observance of this feast began with a Papal encyclical by Pope Pius IX, when he formally defined the dogma of the Immaculate Conception, INEFFABILIS DEUS, on December 8, 1854. Several years later, in 1858, the Blessed Mother gave her name to St. Bernadette at Lourdes stating, "I am the Immaculate Conception."

This stained glass window, pictured above, was donated to the Cathedral of the Immaculate Conception in Portland, Maine by Bishop O'Connell in 1902.

At Marywood, this sacred observance continues through the present day. IHM Sisters and Associates celebrate the Solemnity of the Immaculate Conception as their special feast day, gathering together in various places across the world to pray, renew their vows, and celebrate Mary, the first disciple, and her “YES” to God.
