Sacristans assist the priest in preparing for the Mass. They set out the books for Mass and the items used for communion, monitor the quantity of hosts reserved in the tabernacle, light candles and coordinate the ministers scheduled for the celebration. Afterwards, they put away what was used during Mass and help with the purification and cleaning of the communion cups, and other items used for the celebration. Their commitment involves arriving 30 minutes before Mass begins in order to carry out these tasks. Those new to this ministry would be provided a training and orientation of the sacristy.
