Ushers have long been essential to the dignified progression of the liturgy, aiding parishioners, keeping order, taking up collections, and providing a welcoming face for visitors and parishioners alike.
The ushers should serve to welcome parishioners and visitors and help them to find seating should the church be at or near capacity. As such, the demeanor of an usher should be dignified at all times so as to be respectable and trustworthy should he or she need to exercise authority proper to their ministry.
The ushers should come forward at the beginning of the offertory, either bow or genuflect and begin to go row by row taking up the collection. This should be done expediently, but not so quickly so that people are unprepared to participate.
Ushers should see to it that there are two persons to bring up the gifts: one for the ciborium with the bread and one with the flagon or cruet of wine. Ordinarily the priest will receive the wine and then the ciborium of bread. Those chosen to bring up the bread and wine should be baptized and practicing Catholics.
Second collections should begin after the people have resumed sitting after the tabernacle door is closed and the vessels are being purified.
