Most saints have specially designated feast days. On those days we remember these holy men and women in a special way. The tradition arose from the early Christian custom of commemorating each martyr annually on the date of his or her death, or birth into heaven, a date therefore referred to in Latin as the martyr's dies natalis ("day of birth"). The Church also celebrates special events or happenings in the history of the Church with solemnities, feasts, and memorials. The saint days and other celebrations in the month of December are: 

December 3 - Saint Francis Xavier, priest

December 7 - Saint Ambrose, bishop and doctor of the Church

December 8 - The Immaculate Conception of the Blessed Virgin Mary

December 12 - Our Lady of Guadalupe

December 14 - Saint John of the Cross, priest and doctor of the Church

December 25 - The Nativity of the Lord

December 26 - Saint Stephen, the first martyr

December 27 - The Holy Family of Jesus, Mary and Joseph

December 28 - The Holy Innocents, martyrs

All you holy men and women, pray for us!
