NEW - Laudato Si Activity Patch - Catholic Scouting NEW - Laudato Si Activity Patch - Catholic Scouting Laudato Si is the 2015 Encyclical letter of our Holy Father, Pope Francis, on Care For Our Common Home. Wednesday, June 16, 2021 0 2100 Laudato Si means Praise to You and is part of the beautiful canticle of Saint Francis of Assisi. It reminds us that our common home, the Earth, is like a sister that we share our life with and our beautiful mother who welcomes us into her arms. We need to learn how to care for our common home and understand that how we treat our home reflects how we care for each other.
