The entire parish comes together: the youth, commissions, staff, families, parishioners of all ages. Everyone is welcome and needed. It takes place on the first and second weekends in November and several Naperville churches run Harvest Sunday food collection projects on the same two weekends. Of all the churches involved, the project at St. Elizabeth Seton covers the largest geographical area. Typically, between 60,000 and 70,000 food items are collected by SES alone. These items are sorted, packed and loaded onto trucks for delivery. Two local food pantries and two Chicago area food pantries are filled.
