For the Holy Mass to be celebrated well, there is a need for many people to be involved behind the scenes.
SACRISTAN
Sacristans help to organize and set up for Holy Mass. They are involved with preparing for the Holy Mass and cleaning up after. Sacristans are involved in cleaning and maintenance of the vessels used for Holy Mass. There is a deeper knowledge of liturgical feasts and celebrations.
LITURGICAL ENVIRONMENT
Those who are involved help create prayerful decorations to highlight certain liturgical feasts such as Easter, Christmas, and other feast days. They are involved in the creation and the dismantling of the liturgical environment in the sanctuary, body of the church, entrances and other areas.
