The sacristan is the minister who has overall responsibility for the sacristy.

The primary responsibility of the sacristan is to prepare the worship space before each Mass in preparation for the Eucharist by unlocking the sacristy, preparing the sacred vessels for the liturgy and turning on the lights and sound system.

The Sacristan also ensures that all participants of the Mass from the servers to the lectors to the Eucharistic Ministers are present and prepared to participate.
