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 June (the month of the Sacred Heart of Jesus) are: 

June 1 - Saint Justin, martyr

June 3 - Saint Charles Lwanga and Companions, martyrs

June 5 - Pentecost Sunday

June 6 - The Blessed Virgin Mary, Mother of the Church

June 11 - Saint Barnabas, apostle

June 12 - The Most Holy Trinity

June 13 - Saint Anthony of Padua, priest and doctor of the Church

All you holy men and women, pray for us!
