Does your parish know it?
We're using it at our parish, at all four weekend Masses, like it or not. New Advent's Catholic Encyclopedia describes Veni, Creator Spiritus as the "most famous of hymns". This may be true. But be honest. How many parishes do you think will be singing the "most famous of hymns"?
I say 25% at best. Of that 25%, about 10% of these parishes will enjoy the singing of the Veni, Creator Spiritus by the congregation (as well as the choir). Jeffrey Tucker at NLM figures 10%, maybe 20%.
Yes, even OCP's Today's Missal includes Veni, Creator Spiritus. It's number 84. They're slowly getting better at including MORE actual hymns in their worship aids, including those in chant. Now if we can only get them to clean out the garbage. (GIA's Gather is next!)
