                               The Assumption of the Blessed Virgin Mary
                                            Holyday of Obligation

Mary, the Mother of God, who was preserved from all stain of sin from the moment of her conception by the grace of God, was upon her death raised immediately into heaven so that no corruption of bodily death touched her. The Church gives thanks to God on this day that her greatest member has been so honored. This is doubly important in the United States as Mary has been named our patroness before God.

This day is a Holyday of Obligation for all Catholics during which every Catholic who is able to attend Mass should do so. Masses to fulfill the obligation are:

                              Monday, August 14, at 7:00 PM at St. Mary, Park Forest
                              Tuesday, August 15, at 8:00 AM at St. Mary, Park Forest
                              Tuesday, August 15, at 7:00 PM at St. Liborius, Steger
