One VERY liberal parish in my area has a duet. The laity basically sit and listen to the concert going on.
My other bugaboos are, using the piano when there is an organ AND the “raising up” of the cantor because it is assumed that the congregation is too stupid to know when to sing.
Get the musicians to the back where they belong and let’s pay attention to The Body, Blood, Soul and Divinity instead.
:-) Reminds me of my former RC parish, one of the largest in this area. (Recall this is Bishop Hubbard territory where anything goes!) This one Sunday, the 'light in the loafers' pastor brought in a pianist to play background music during the quiet moments of the mass, like the Consecration Nothing like watching a priest elevate the host to background music.
Our bishop reaches mandatory retirement age in 2013. For decades now, many catholics in the diocese have been praying that his successor will be appointed by a conservative minded pope. It will take decades to turn this diocese around.
Please check out the link I posted above. Finding parishioners in liberal parishes (or dioceses) amenable to its message is the greatest challenge, especially when they have been told their methods of worship are normal and desirable.
