I’m confused, too–especially by the info given from Colin Donovan. In it, Colin says that laypeople do not have the spiritual authority to confer a blessing. Yet, the quote from the catexhism given near the beginning of this thread clearly enunciates that laypeople do, indeed, have the spiritual authority to confer blessings–but that this authority is regulated by church law particularly when it involves ecclessial action.
Only priests can offer blessings, but the common priesthood is a real priesthood. It isn’t just a concept meant to placate the laity. The ministerial priesthood is configured for a different type of service, but that doesn’t make the universal priesthood any less official or dignified.
Colin’s answer seems to contradict the catechism reference. I don’t hold an STL, but I’m perfectly fine with an answer of, "yes, laypeople, as participants in the one priesthood of Christ can confer blessings, but the Church has the authority to regulate when and in what situations these blessings may be given.
I’m not fine with an answer that diminishes the fullness of the Church’s teaching regarding the priesthood of Christ and the ways in which the lay and ordained members of his body participate in it.
