is the name given to the 5 Sundays from 1st September to the 2nd Sunday in October. Using the Lectionary readings, it is an opportunity to focus on creation and re-consider our responsibilities for the stewardship of the earth.
Harvest Festivals will usually fall in this period, and 4th October is the Feast of St Francis.
