In the grand scheme if the music we are playing and singing in church is pedestrian and about us rather than God, then yes, the style does matter. There is a widespread misunderstanding in the Church today about what the Mass actually is. The Sacrifice of the Mass was given to us by God, it is not us giving it to Him. It is not about “fellowshipping” or singing about how great we are. It is the perpetual sacrifice of Christ re-presented to the Father. It is the prayer of God the Son to God the Father.
It’s clear that the styles we have been singing in (combine with the lyrics and the decline in the quality of catechesis) truly do matter.
So why haven’t the Bishops spoken up on this?
