1 min read

This lecture explores Pope Francis's thought on the relationship between Eucharist and ecology, especially as articulated in his encyclical, Laudato Si', and in his apostolic letter on liturgical formation, Desiderio Desideravi. It also briefly reflects on Pope Leo and the "Mass for the Care of Creation" released in July 2025.
