Sorry, but I don’t get how a ‘style’ of music can be secular (or religious for that matter). The only thing that I ever thought made a song secular or religious was the lyrics. How can you play a guitar in a way that is distinctly secular? Or play it in a way that is religious? There are secular artists who use things like church organs and choirs (common to a lot of religious music), does that mean they are writing secular songs in a religious style?
Do you call a style of music ‘secular’ just because in the past it has been used by secular artists with secular lyrics? Wouldn’t that be like saying that building things with bricks and mortar is a secular style, because before churches, people used to use bricks and mortar to build secular buildings? Hence we shouln’t build churches out of them, we should make our own, religious style of making buildings?
I can understand people saying not to use some modern Christian music in the liturgy. But that is mostly because of the lyrics rather than the style of music I think - the words in our liturgical music are often from the bible, or else could be used as words of the liturgy even if they weren’t in musical form. The lyrics of a lot of Christian artists today, although they are in praise God, are not always appropriate for the liturgy - they really should be checked out by the priest before being used.
However, even if music is not appropriate for the liturgy, as that is very sacred, it doesn’t mean that that music is not good for general listening by Christians. Same as how we don’t have readings at mass from modern books written by Christians, we only have readings from scripture, but that doesn’t mean those books aren’t good for reading.
I could also understand if you were complaining about Christian artists living the life style of secular rock artists (drugs and groupies) because thats obviously secular and a bad example to young people. But just playing music in a certain style? I don’t think so.
