Q: At my parish, the Pastor and parochial vicar have recently had an acolyte turning pages of the Roman Missal during Mass. I’ve never seen this before. A new rubric?

A: There’s no new rubric, but the GIRM has always said that an acolyte assists the priest in any way required, and he assists at the chair and at the altar (187). The missal doesn’t assign page-turning to anyone, but it would tolerate this practice if it helps the priest locate the right page or keep his hands extended while he prays.
