Novena in Preparation for the Immaculate Conception
December 4

In February of 1849 Pius IX asked for a survey of opinions about the possibility to define the dogma of the Immaculate Conception.

Responding to the positive result of the survey Pope Pius IX on December 8, 1854 promulgated the Dogma of the Immaculate Conception with the bull Ineffabilis Deus.

"We declare, pronounce, and define that the doctrine which holds that the most Blessed Virgin Mary, in the first instance of her conception, by a singular grace and privilege granted by Almighty God, in view of the merits of Jesus Christ, the Savior of the human race, was preserved free from all stain of original sin, is a doctrine revealed by God and therefore to be believed firmly and constantly by all the faithful."

Already in 1854 there was support for a corresponding definition regarding Mary’s Assumption.

Four years later, on March 25, 1858 in Lourdes, a lovely Lady revealed herself to Bernadette Soubirous as the Immaculate Conception thus confirming the truth of the Catholic doctrine.

And the angel came to her and said, "Rejoice, Highly Favored One! The Lord is with you." May we, too, be conscious of our calling!
