December is the Month the Church Dedicates to the Immaculate Conception
“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.”
(Given at St. Peter's in Rome, the 8th of December, 1854, Pius IX)
