From USCCB:
Catholic priests will now be able to celebrate Mass “for the care of creation” after the Vatican announced that a new formulary of prayers and biblical readings for the Mass will be added to the Roman Missal — the liturgical book that contains the texts for celebrating Mass in the Roman Rite of the Catholic Church.
The new formulary, or specific set of texts and prayers for Mass, will be added among the “civil needs” section of the “Masses and Prayers for Various Needs and Occasions” listed in the Roman Missal. The current missal, approved by St. John Paul II in 2000, lists 17 “civil needs” to offer Masses and prayers for, including “for the nation or state,” “after the harvest,” “for refugees and exiles” and “in time of earthquake.” The missal lists another 20 particular needs for the church and 12 for other circumstances.
