Hi, what concerned me was something from the USCCB:
usccb.org/liturgy/innews/September2006.pdf
section 5 that says
“For exposition of the Blessed Sacrament in the monstrance, four to six candles are lighted and incense is used. For exposition of the Blessed Sacrament in the ciborium, at least two candles should be lighted, and incense may be used.” (HCW, no. 85)
and section 6:
“The minister, if he is a priest or deacon, should vest in an alb, or a surplice over a cassock, and a stole. Other ministers should wear either the liturgical vestments which are used in the region or the vesture which is suitable for this ministry and which has been approved by the Ordinary. The priest or deacon should wear a white cope and humeral veil to give the blessing at the end of adoration, when the exposition takes place with the monstrance; in the case of exposition in the ciborium, the humeral veil should be worn.” (HCW, no. 92)
When exposition and reposition is done by a lay person, generally no vestments are used, there is no incense, and there is certainly no benediction. I was wondering if, by omitting the incense and vestments, the priest was functioning “as a lay person” which would not be allowed. E.g., if a priest or deacon is available it would not be licit for a lay person to expose the Blessed Sacrament, even though it is if there is neither priest nor deacon available.
