If you look to the choir loft as you are leaving the church at Holy Rosary, you'll notice that the last stained-glass window to the right of the loft is an image of Saint Cecilia. She is the patroness of music, which comes from the story of her hearing heavenly music when she was married.
Each time we celebrate the Mass, we both make present and join in the heavenly celebration of the Lamb's Supper ourselves. For this reason, the church places value both on the liturgy itself and the elements with the liturgy, with music having an especially important part in elevating us to more fully participate in the heavenly celebration.
So what would heavenly music sound like? Well, that's probably a question we can't answer perfectly. But the church has a few ideas. One of the most important documents on liturgy from Vatican II isSacrosanctum Concilium (Constitution on Sacred Liturgy). There are a lot of guides and directions outlined, but there is a special exhortation that "bishops and other pastors of souls must be at pains to ensure that, whenever the sacred action is to be celebrated with song, the whole body of the faithful may be able to contribute that active participation which is rightly theirs." (SC, 114).
In this way we begin to see that heavenly music is the song of all creation, most especially our prayerful worship of the Lord in song! Next week we'll look at the ways the church envisions our joining together in sung prayer.
