Why do we bow/bow back when being incensed?

[Elzee]

I was recently at a parish where the deacon incensed the congregation - first one side, then the other. He incensed them, bowed to the people, then everyone bowed back.

What’s the significance of the bowing?

I think it is a matter of decorum/protocol. The GIRM says

1. 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.

It’s basically saying “Thank you” without speaking.

Bows were formerly much more common, even in social interaction, than they are today.

For example, a gentleman would always bow to a lady in the street, who would curtsy in response.

It just seems polite.

Most gestures of respect have some form of acknowledgment.

Salutes, bows, Waves, and tips of the hat are all normally “returned.”

“Rev. Father, Bless!” is normally responded with a blessing.

Hugs are uncomfortable if not returned. As Fr. Surge once said, “It’s not easy to hug a stick.”

Pax vobis cum… Et cum spiritu tuo.

In the case of bowing before being incensed, one is also bowing in submission, acknowledging that holy fragrance is being shared, and that one is part of the group being incensed, and giving permission, as well.

Further, remember the prayer used when incense is added: May our prayers rise to heaven like the smoke of this incense.

Remember also: incense is used as a symbol of purification, as well, since its fragrance lingers on those incensed.
