A reader writes:
When the priest walks around the church incensing, do the people in the congregation make the Sign of the Cross when he gets to their area (they way they do when he sprinkles holy water)? I am unsure whether I should bow, make the Sign of the Cross, or what.
A check of the (current and previous) GIRM reveals little on this question. Here is the most significant discussion of what actually happens when things and people are incensed:
277. The priest, having put incense into the thurible, blesses it with the sign of the Cross, without saying anything.
Before and after an incensation, a profound bow is made to the person or object that is incensed, except for the incensation of the altar and the offerings for the Sacrifice of the Mass.
The following are incensed with three swings of the thurible: the Most Blessed Sacrament, a relic of the Holy Cross and images of the Lord exposed for public veneration, the offerings for the sacrifice of the Mass, the altar cross, the Book of the Gospels, the Paschal Candle, the priest, and the people.
The following are incensed with two swings of the thurible: relics and images of the Saints exposed for public veneration. This should be done, however, only at the beginning of the celebration, after the incensation of the altar.
The altar is incensed with single swings of the thurible in this way:
a. If the altar is freestanding with respect to the wall, the priest incenses walking around it;
b. If the altar is not freestanding, the priest incenses it while walking first to the righthand side, then to the left.
The cross, if situated on or near the altar, is incensed by the priest before he incenses the altar; otherwise, he incenses it when he passes in front of it.
The priest incenses the offerings with three swings of the thurible or by making the sign of the cross over the offerings with the thurible, then going on to incense the cross and the altar.
That’s it. It just says that the priest incenses the people with three swings of the censer. It doesn’t say for the people to do anything.
Neither does a check of the rubrics (so far as I could see) direct the people to do anything when they’re incensed. Checks of the BCL Newsletter and the Documents on the Liturgy (a standard collection) also turned up bupkis.
Thus, unless someone can show a binding document that says otherwise, it seems to me that the default option is for the people to do nothing.
That is definitely not the custom in some rites, however. In some Eastern rite services I’ve been to, it’s clearly the custom for folks to cross themselves.
Also, since the above text directs the incensor to make a profound bow (a bow of the body) before he incenses, it seems natural for folks to want to bow back to him. That’s a human politeness impulse, though. One might argue that in the act of incensing the people the incensor is being directed to show reverence to them on account of their sacredness to God (being made in the image of God). Since they are the recipient of this reverence and are not directed to reciprocate, one could argue that they ought not reciprocate at this point.
It seems to me that, although the default option seems to be to do nothing, Rome generally allows the laity a considerable amount of leeway in terms of their own gesture and posture (after all, we laity are peasants just in from slopping the pigs in the grand scheme of things; you can’t expect too much from us) and so (unless a binding document says otherwise) I don’t think Rome would mind if the faithful wanted to express their own piety by crossing themselves or bowing when they’re incensed.
It’s certainly better than forming a mob with pitchforks and torches.
