When you are preparing the music for Mass, it is important to remember that a sung Mass is NOT A MUSICAL. They don’t sing Gregorian Chant on Broadway or stop at the interval to say a decade of the Rosary, so why would you think it is appropriate to sing a song from a hit-show at Mass?
For example, this week’s Introit is Populus Sion taken from the Prophet Isaiah:-
People of Sion, behold the Lord will come to save the Gentiles, and the Lord will make the glory of his voice heard to the joy of your hearts.
This glorious introit filled with optimism and hope perfectly sets up the theme of waiting, waiting with joy in hearts as we prepare for the coming of the Lord.
So why would you ever think that THIS would be a suitable replacement?
