Q:  Please alert me to liturgical documents that encourage silence at various intervals throughout Mass and other liturgical celebrations.
A:  For the Mass, the easiest way to find references to silence is to do a search on the General Instruction on the Roman Missal. Here’s the link to the GIRM in Australia: Search for “silence” and you’ll find lots of references. You may also apply similar principles to the other liturgical celebrations.
