On the day of 8 December
The solemnity of the Immaculate Conception of the Blessed Virgin Mary, truly full of grace and blessed among women, preserved at very first moment of her conception from the stain of original sin through the foreseen appearance and saving death of the Son of God by a singular privilege of God, which was solemnly defined on this very day by Pope Pius IX as a fixed dogma handed down in truth from ancient times.
