It’s required. It only comes up once a year. Most pew people don’t know the tunes. How would you handle it? All the verses or just some? Is it okay to have the cantor or choir sing it alone? Would you put in a refrain for people to sing? Would you use the Taize Veni Sancte Spiritus or what’s in your missalette or hymnal? Have you ever used Alstott’s adaptation that fits the tune ODE TO JOY? Would you have the people recite it? Would you have the lector recite it? How is your parish doing it, and what would be your fiat, were you sitting in the big chair?
