Bishops have the authority to authorize or suspend the public offering of Mass within their diocese. In addition, they may offer the faithful in their care dispensation from their Sunday Mass obligation because of health concerns or during natural disasters. This dispensation means you do not commit a mortal sin by missing Mass.
However, this does not release the faithful from honoring the Lord’s Day on Sunday. We encourage all Catholics to honor this day by reading Sacred Scripture, making a Spiritual Communion while watching Mass on television or streamed online, and praying the Rosary or other prayers.
