It takes a lot of people to properly get the Mass off the ground at any given parish. Paragraph 105 lists some of the people that are often not thought about.
The first is the sacristan. The sacristan works primarily in the sacristy which is the place where everything for the Mass is prepared. Of primary concern for the sacristan is all of the liturgical books needed for all of the rites (which may be more than many realize) all of the vestments “and other things necessary for the celebration of the Mass.This last part can be expanded or retracted depending on the policy of the parish. Does a sacristan simply make sure that the vestments are properly stored or do they set them out for Mass, mend and launder, order and create vestments? There are chalices and ciboria, thuribles and aspergilum, candles, purificators and corporals. There are flowers and decorations, holy water fonts server’s vestments. The list (and the amount of time) can be great. You are very fortunate if you have someone who is not only talented and efficient, (here we go into opinionland,) but also subtle (when things to south) and who makes people feel comfortable and welcome in the sacristy.
