What does "Ite missa est" mean? :-)
Jeff Morse reads a rule and concludes that English motets are allowed within the context of Mass. A now-deceased member of the schola with which I sing was adamant that the rule of Mass prohibited such stuff. These two people, to the best of my knowledge, never met each other. I won't second guess either one at this point.
I find myself singing This is the record of John, but not at Mass. I used to sing Nolo mortem peccatoris, but I wouldn't recommend its use within Mass so as not to scandalize those who are sure that no vernacular work belongs inside the Mass. We often sing vernacular hymns during processions, in and out, but not inside the Mass.
