A very nice argument by Cardinal Arinze, who was the head of the Congregation for Divine Worship and the Discipline of the Sacraments. This is how and why music, liturgy and all parts of the Mass must be proper (to refute those who says that these are irrelevant), because exactly they help us to be closer to God, to make the worship at the Mass truly a worship, and not instead becoming a glorification of the priest, self, or anyone else besides God.
The parish priests, anywhere in the world, Singapore, Asia, Africa, Europe, and others must make sure that rock music, loud music, clapping in the Mass, even within song is not relevant and therefore must not be used. A hymn, a proper Catholic hymn sung with reverence is much more appropriate and should be promoted.
The way to evangelise to our Catholic youths and youths in general is not to include contemporary music into our worship that makes it less than appropriate, just so that we can attract them. Those music and clapping actions, are more suitable for rally sessions or praise and worship, but NOT for the Mass.
The best way? Introduce our youths to the proper and solemn music, many of which are beautiful and no longer heard today, sunk by all the ugly contemporary music the likes of those by Lady Gaga, Psy, and so many others, which are contemptuous twisting of the true beauty of music, which purpose, like what the angels are doing in heaven, is to praise the Lord in His glory. Gregorian chants in Latin and other chants and hymns in the vernacular languages are the way to go.
We are the Church, and we worship the Lord in the Mass. We are not going to a marketplace or attending music concert when we attend the Mass, instead in the Mass we are with the Lord and through our tongues we praise Him with glorious and beautiful hymns appropriate to worship Him!
