From the flyer promoting "Liturgical Ministry Sign-up Sundays, Oct. 11 and 18" for Bellarmine Chapel at Cincinnati's Xavier University:
BREAD BAKERMaking the bread of life, a ministry of Christ’s presence! A simple recipe will be sent to you. A pizza pan works well for the baking. Best to experiment a few times before you’re “up” for a Sunday. Bread needs to arrive ten minutes before the Liturgy begins.
