September 1st is World Day of Prayer for the Care of Creation, celebrated in the Orthodox Church since 1989 and by the Roman Catholic Church since 2015. It is the beginning of the Season of Creation, which ends on October 4th, the feast of St Francis of Assisi.
For all those wishing to celebrate a Catholic season of creation during the four weeks of September 2017, the Columban Mission Centre, Australia is offering a welcome resource for Sunday liturgies. Each week focuses on a particular theme.
The material is also a rich resource for personal or community prayer and reflection during September.
