The Office of Worship promotes and facilitates the good stewardship of the sacred liturgy in the archdiocese and within each parish through catechesis and training. Together with its chief steward, the archbishop, the people of God will seek to enhance the beauty of the sacred liturgy so that they may be “actively engaged in the rite, and enriched by its effects;” and in so doing, care for the poor and vulnerable of the world.

In addition to Sundays, Catholics in the United States are obliged to attend Holy Mass on the following holy days of obligation in 2017:
Sunday, January 1: The Solemnity of Mary the Holy Mother of God falls on a Sunday and is celebrated that day.
Tuesday, August 15: Solemnity of the Assumption of the Blessed Virgin Mary
Wednesday, November 1: Solemnity of All Saints
Friday, December 8: Solemnity of the Immaculate Conception
Monday, December 25: Solemnity of the Nativity of the Lord*
Observance of the Solemnity of the Ascension is transferred from Thursday of the Sixth Week of Easter to the Seventh Sunday of Easter (from Thursday, May 25, 2017 to Sunday, May 28, 2017).
* The Monday-Saturday rule does not apply to the Solemnities of Christmas (Dec. 25) and the Immaculate Conception (Dec. 8). Catholics are obliged to attend Holy Mass on these days, even when they fall on a Monday or Saturday. For the other holy days of obligation (Jan. 1, Aug. 15, Nov. 1), the obligation is removed when they fall on a Monday or Saturday (Decree of the National Conference of Catholic Bishops, December 13, 1991)
