Pious exercises and devotions. Let’s keep clear what we’re talking about here …
13. The objective difference between pious exercises and devotional practices should always be clear in expressions of worship. Hence, the formulae proper to pious exercises should not be commingled with the liturgical actions. Acts of devotion and piety are external to the celebration of the Holy Eucharist, and of the other sacraments.
The occasional practice of saying the Hail Mary during Mass comes to mind. Wholly valid form, as it derives from Scripture and is suggestive of liturgy. I’m aware of the practice of saying the Anima Christi after communion–I wonder about that, too.
On the one hand, a superimposing of pious and devotional practices on the Liturgy so as to differentiate their language, rhythm, course, and theological emphasis from those of the corresponding liturgical action, must be avoided, while any form of competition with or opposition to the liturgical actions, where such exists, must also be resolved. Thus, precedence must always be given to Sunday, Solemnities, and to the liturgical seasons and days.
In other words, a devotional form shouldn’t overwhelm the observance of Sundays, of major liturgical feasts, or the liturgical season.
Since, on the other, pious practices must conserve their proper style, simplicity and language, attempts to impose forms of “liturgical celebration” on them are always to be avoided.
And likewise, liturgical elements shouldn’t intrude on pious practices. Hmmm … Does this mean the “Pour forth, we beseech you” prayer in the rosary is inappropriate? I have to say from personal experience that I learned the Rosary without all those extra prayers, including the Fatima utterance. When I’m with the students, I usually remain silent for those “extras” and confine myself to the basics as I was taught.
To be honest, I haven’t given this intermingling of practices a whole lot of thought. I’m skeptical on an absolute apartheid between liturgy and devotions. But certainly, great care is needed. A local community can add significant “tradition” and it can be very difficult to undo it.
