Hahaha, yes. I know several professional musicians who are Catholic, but hate the fact that music ministry is so poorly compensated in the Catholic parishes, in comparison to, say, your Baptists. Or they hire on as Music Director with a very distinct job description of a, b, and c— and all of a sudden, they’re supposed to be volunteering an extra 20 hours per week on d, e, f, g, h, and i, which weren’t part of the original agreement.
If you want a volunteer amateur, you can have a volunteer amateur. If you want a paid professional, you can hire a paid professional, and compensate them accordingly. But just because you run into a few artistes who faint at the thought of sullying Art with Money— it doesn’t make it acceptable to say, “I know you love playing music! So you can come play music at my wedding! For free! And won’t that be awesome!”
