On May 18, 2020, Pope Francis ordered the inscription of Saint Faustina Kowalska, Virgin, into the General Roman Calendar. St. Faustina is celebrated each year as an Optional Memorial on October 5.
The proper liturgical texts were released by the Holy See in Latin. English and Spanish translations must be approved by the USCCB and confirmed by the Holy See before they can be implemented in the United States.
Below are interim liturgical guidelines for the celebration of St. Faustina Kowalska:
From the Common of Virgins: For One Virgin, or the Common of Holy Men and Women: For Religious.
