Mercy Tips to Care for Earth

Develop a Sustainability Habit this Season of Creation

By Marianne Comfort, Mercy Justice Team 

Pope Francis invites Catholics around the world to celebrate the Season of Creation, September 1 through October 4, with prayer and action. 

This year’s theme is “Let Justice and Peace Flow,” based on a scripture passage from the Book of Amos: “But let justice roll on like a river, righteousness like a never-failing stream!” (5:24). We are called to join the river of justice and peace, to take up climate and ecological justice, and to speak out with and for communities most harmed by climate injustice and the loss of biodiversity.
