The sacristan is responsible for the overall preparation of liturgical celebrations. Every element in the sanctuary needs to be in order, clean and ready for the Eucharist celebration. He/she arranges books needed for the celebration, marking all of the divisions. He/she also lays out the vestments and anything else needed for the celebration, such as chalices, cruets, linens, oils, processional crosses, candles and torches. The sacristan takes care of ringing the bells that announce the celebration.
