The Rev. Arnaud Devillers believes there are probably still some Catholics in Quincy who are unfamiliar with what is going on at St. Rose of Lima Church since it reopened last November. St. Rose, which was closed for two years as a part of local Catholic downsizing, is where the traditional Latin Mass has been celebrated since its reopening. Sunday will mark the one-year anniversary of the return of the Tridentine Mass to the city. “This is not something outside of the church,” Devillers said. “Everyone is welcome. No special permission is needed. We work closely with all of the other (local Catholic) pastors.” Devillers said a congregation of about 200 gathers at either 8 a.m. or 11 a.m. on Sundays and about 40 at 12:10 p.m. each weekday at 12:10 p.m. for the Latin Mass. He estimates about 80 percent are from Quincy-area parishes and the rest mostly from Northeast Missouri, with a handful of regulars from Jacksonville and sometimes St. Louis.
