Priest blesses motorcycle during Mass. Is that kosher?

This Q&A caught my eye, via Zenit: 

Q: A few weeks ago, in a Sunday Mass, the priest asked the congregation to leave the church and go outside in order to bless a motorcycle. Then he gave us the final blessing. Many people got angry. I know he can bless a motorcycle. My question is, can he do that during the holy Mass? – A.A., Luque, Paraguay

A: I would say that the priest went too far in involving the entire congregation in an evocative blessing, and it should not have been done within Mass.

The General Introduction to the Book of Blessings has:

“28. Because some blessings have a special relationship to the sacraments, they may sometimes be joined with the celebration of Mass.

“This book specifies which such blessings are and the part or rite with which they are to be joined; it also provides ritual norms that may not be disregarded. No blessings except those so specified may be joined with the eucharistic celebration.”

Later in the Book of Blessing when we come to the Order for the Blessing of the Various Means of Transportation (both chapter and paragraph numbers vary in the different editions), we find that there is no mention whatsoever of uniting this blessing with Mass.

Read the rest. 

Like a lot of deacons, I’ve done my share of blessings for automobiles (though never a motorcycle!). Never done it during Mass, though.

And, based on this answer, that’s probably wise.
