I am currently the only Sacristan at our second (handicap-accessible) Parish Center. I have everything set up for the Priest and Servers 1 to 1 1/2 hours prior to Mass. Since our current Priest places the Monstrance on our Altar for 20 minutes prior to Mass, I also remove that (after he carries out the Holy Eucharist), and place his Mass book on the altar along with a small gold crucifix that sits in the center of the Altar toward the congregation. We also have a 4’ tall wooden Crucifix behind the Altar on the wall. I have the Holy Water containers filled, the wine prepared, all the chalices on the side table along with the Purificators, make sure there are sufficient Hosts for all attending (since we get many, many visitors during warm seasons) and add more if some come at the last minute just prior to Mass and make sure there are enough for all. Everything is ready prior to our Priest beginning Mass and the opening Hymn. I then sit near the front (as I often have to fill in as an EMHC or Server if the one scheduled by me doesn’t show up – yes, I also do the scheduling for Lector, EMHC’s, Servers and Ushers for 2 months at a time, which they receive 2 weeks prior to new schedule starting). If I do not need to serve, I can then sit with the Congregation and concentrate on the Mass. After Mass, I collect the Purificators, any Altar cloths which become stained for laundering, then wash and dry and replace all vessels, move the Mass Book back to the side table, and put everything away in a cabinet, leaving only the candles (which I extinguish after Mass) and the small Crucifix on the Altar as well as a clean Altar cloth. Can’t you do it all an hour or more ahead?? That’s the way I do it every Vigil Mass, and do the same for all weddings. The Priest takes care of his own vesting, and the Parish Secretary takes those for cleaning when needed, so I don’t need to do those. (Can’t anyway, as he keeps his office and the Parish main office locked and I’m not allowed to have a key). I then get the collection in a Bank bag from the head Usher and drop it in the night deposit box when I lock up the Parish Center and check that all extra lights are off and all doors are locked. It’s a lot of work, but by spacing it out this way, I can concentrate on the Mass, even if I am serving in one capacity or another at the Mass. And I’m 73 years young, and can keep up with it all. I just have to leave for Mass 2 hours earlier.
