(Clare, I’m not disagreeing with you here! I’m just using your post as a springboard for my own comments. )
I think we need to give young people credit for being their own individuals. Like adults, they are going to have their own liturgical preferences.
I have two teenagers (and 4 younger children). They’ve been exposed to a wide variety of Catholic worship: We are Byzantine, through homeschooling friends we occasionally attend a TLM, they’ve experienced very solemn Novus Ordo Masses (the Chrism Mass at the Cathedral, for example), Masses dominated by Praise and Worship music and just standard, run-of-the-mill parish Masses. They like aspects of each. This weekend, we were away from home and attended a local parish. The Mass was fine. The homily was fantastic and engaged even my 8-year-old. The music was modern - a couple of hymns, but mostly praise and worship, with the lyrics projected onto a screen above the altar. Three volunteer singers were accompanied by a drummer, tambourine, and guitar. My 13-year-old daughter asked to move to the back of the church because the drums hurt her ears (she has sensory processing issues). This same kid has mentioned more than once that she wishes Byzantine worship were a little more exciting and that we sang songs in our Byzantine parish like they do in other parishes. My 15-year-old son adamantly disagrees. He loves chant and strongly believes that worship of God should be solemn. He does prefer Melkite chant to Ruthenian, though. My 11-year-old whined, but he whines about everything. My 8-year-old said that the screen with the words was distracting. I think my daughter with the sensory issues would actually prefer a low Mass, though I’ve never asked her. Incense bothers her, too.
My point is that we cannot assume that one-size-fits-all for our young people. Where ever they are, whatever form the Mass takes in their home parish, will be the backdrop for their Catechesis and formation as Christians. They seek truth and truth can be found in every approved form that the Mass takes. They need something solid and real. Kids usually don’t get to choose where they go. We have to give them the best no matter where their parents bring them to church.
