I had always thought the Book of Blessings was liturgical prayer, but I’m hard-pressed to imagine that a Blessing of Technical Installations or Equipment is really necessary for the life of the Church.
I tried to find a better definition, or a more clear explanation of what constitutes the difference between liturgy and non-liturgy.
I agree that a blessing of something technical is not really necessary. I suppose the idea might be that it’s necessary to have such blessings in the Church’s “toolbox.”
Necessity can be one of the criteria, but I don’t think we can take that too far (as you’ve just illustrated).
I’ll quote the section from #11 at the end of my post here.
I’ve always understood the distinction between liturgical and other was that when it comes to liturgy, the Church has an official rite which is obligatory. That would make Baptism liturgy but Stations of the Cross non-liturgy, since the later is flexible. Even that would have exceptions in both directions.
I think this sort of thing is difficult to actually define.
In the Catechism, chapter 4, article 1, sacramentals are placed under the heading of “Other liturgical celebrations.” But then again, so are forms of popular piety.
So where do they belong? Is popular piety liturgy? I could imagine it might be (I can think of a few examples that I would personally think would be called “liturgical.”)
Without hesitation, I would call the prayer from Vatican II non-liturgy. At the same time though, I cannot find, nor can I think of my own, a way to actually define the distinction.
Even a quick check of the Catechism doesn’t yield any clear definition.
I just don’t know how I would define the difference.
I much prefer the Eastern vocabulary. ‘Liturgy is the Divine Liturgy.’ Period. Clear and precise. Alas, in Western vocabulary, it’s not that easy.
Here’s the section from the Directory:
The faithful should be made conscious of the preeminence of the Liturgy over any other possible form of legitimate Christian prayer. While sacramental actions are necessary to life in Christ, the various forms of popular piety are properly optional. Such is clearly proven by the Church’s precept which obliges attendance at Sunday Mass. No such obligation, however, has obtained with regard to pious exercises, notwithstanding their worthiness or their widespread diffusion. Such, however, may be assumed as obligations by a community or by individual members of the faithful.
