I have had a question posed to me that I have never thought of before. It is a usual practice that two members of the Melchizedek Priesthood perform administrations with one anointing and the other then confirming the anointing and then to provide an additional blessing. I am aware of instances where if only one worthy Melchizedek Priesthood holder is present they they are able to do the entire ordinance themself. So why is it preferable when possible that 2 perform the ordinance in its entirety?
This definitely is a question to ponder, and a question which may not have a particularly solid answer.
The question can also be asked, “Why do we have two priests bless the sacrament, when one priest is sufficient to bless both the bread and the water?”
I would assume it is preferable because the blessing of the sick is actually two parts: the anointing and then the blessing. However, if two are not available, then one Melchizedek priesthood holder is able to act in both parts.
Great question, however there really isn’t any solid or concrete answer.
