Precisely! The word “blessing” has so many different meanings. We can “bless the Lord” but that doesn’t mean that we are making God into something holy–of course we all know this. When we say that we “bless” God we are realy saying that we are thanking Him for His blessings upon us. We even use the word “bless” (or its variants) in purely secular settings. “The boss gave his blessing to the new policy” doesn’t mean that someone put the paper on his desk and made the sign of the cross over it–we all know this, and take it for granted.
Laypersons can “bless” a person or thing in the sense of asking God’s blessings on that person or thing. A good example is Grace before a meal “Bless us O Lord…” Yet, this “blessing” the meal is different and distinct from imparting a blessing upon it. When we walk into a church, we “bless ourselves” with holy water, making the sign-of-the-cross. This again is distinct from the actual blessing that the priest imparts at the end of Mass. Catholics understand the differences here, but when it comes to something like the St. Blaise day ritual, that’s where we tend to lose our perspective because the external appearances of what is happening makes that distinction very difficult. The actual ritual for St. Blaise day makes a clear distinction between a blessing imparted by a cleric and a prayer said by a layperson. This doesn’t become clear until one actually looks at the two alternate rituals. If done by a cleric, the words are accompanied by the sign of the cross and invoking the Blessed Trinity–that’s a proper blessing. When it’s done by a layperson, both the cross and the Trinitarian formula are not done, making it a prayer rather than a proper blessing.
