National Day of Prayer and Penance
In February 2002, the Catholic Church established that throughout the United States, January 22nd would be observed as a day of prayer and penance for the offenses to human dignity caused by abortion [General Instruction of the Roman Missal, no 373]: In all the dioceses of the United States of America, January 22 (or January 23, when January 22 falls on a Sunday) shall be observed as a particular day of penance for violations to the dignity of the human person committed through acts of abortion, and of prayer for the full restoration of the legal guarantee of the right to life. The Mass ‘For Peace and Justice’ (no. 22 of the ‘Masses for Various Needs’) should be celebrated with violet vestments as an appropriate liturgical observance for this day.
