I am looking specifically to a document which states that EMHCs are not to given any type of blessing; there are many types of blessing, and for lack of a better term they rank from informal to bvery formal (my words); from something as simple as “May God bless you” (very informal, and one that anyone could give in ordinary conversation) to more formal (one, e.g. from the Book of Blessings, e.g. by parents) to more formal by a priest or deacon (e.g. blessing a rosary) to specific blessings at Mass (more formal, byt he priest or deacon specifically) to a blessing with the Eucharist (e.g. at Benediction; noted as specifically reserved for the priest or deacon).
Specifically, what I am asking is, what is the source or authority which would either forbid an EMHC, or limit to a deacon or priest, a prayer or blessing such as “May the lord keep you and bless you”?
I am not trying to be a pest, and I don’t particularly have a dog in this fight. However, I do see at times in these threads people going from specific rules to generalizations that are not supported.
The quote from “On Certain Questions on Collaboration” is not on point as it does not adress the issue at hand.
