The occasional music director gets a request for something like this. We covered the scrutinies here years ago. Here is the discussion on the intercessions.
The North American Forum promoted a deeper experience of these. These RCIA petitions are not “general” intercessions as such, they do have a similar structure and certainly could be sung. If a parish isn’t singing the intercessions (or at minimum the response) then singing these do serve to highlight this portion of the scrutiny. It elevates it from a parish assembly “eavesdropping” on what is essentially an examination of conscience. It might even serve as an examination of the consciences of the assembly, and spark important reflection before people approached their confessors.
Most catechumenate directors I’ve worked with were Forum-trained, so this was about the time of year that I would get index cards or slips of paper with particular sins. It was my task to distribute them through three weekends.
When I got something like “doubting God,” I might elaborate a bit and look for an apposite virtue in the readings or psalm. In Psalm 27, we sing of the Lord being light and salvation, so my full petition might be something like “From doubts we have of you, O God; deliver us with the light of your Word, we pray … Kyrie eleison.”
I was slightly surprised at the dismissive tone in some of the discussion here. The original purpose of Lent was to provide an intense preparation for baptism. Just because a person was unbaptized, that didn’t mean the Church spared itself the effort of cultivating a sense of sin in newcomers who were committing to Christ.
I’m also surprised that reform2 musicians would decline an opportunity to sing the Mass, that is: a portion of the Mass that is eminently suited to chanting.
My new parish does not sing these. I think I will miss that this year. But for parishes that are considering it, where would you weigh in with your directives? Sit in the purple chair and dictate: sung intercessions, possibly with locally-composed petitions? Or not?
