Q: I’d like to use lay people to expose and repose the Blessed Sacrament for adoration when no priest or deacon is available. Do I have to use men whom a bishop has instituted into the order of acolyte?
A: The Order for Exposition of the Holy Eucharist says in paragraph 91 that a “special minister of communion or another person appointed by the local Ordinary” may expose and repose the Blessed Sacrament in the absence of a priest or deacon. Such a person may open the tabernacle and place the host in the lunette for adoration. “It is not lawful, however, for them to give the blessing with the sacrament.”
So any of your extraordinary ministers of holy communion may set up and close down a period of adoration.
