Our Mission
Inspired by the hope of Christ, the Laudato Si Commission (LSC) seeks to better align the Archdiocese of St. Louis to our Catholic Teaching on Integral Ecology as exemplified in Pope Francis’ Laudato Si encyclical through education, formation, collaboration, and community outreach.

Resources
The Missal and Lectionary texts of the Mass “For the Care of Creation” / “Por el Cuidado de la creación” for use in the Dioceses of the United States of America were confirmed by decree of the Dicastery for Divine Worship and the Discipline of the Sacraments on August 4, 2026 (Prot. n. 447/6).
The World Day of Prayer for the Care of Creation is observed on September 1 each year. Find more resources here:
