Now, if you're like me, you read that line and say to yourself, "Uh oh, wacky lib alert!" I have found that, usually, any time someone wants to cite the "mind and wishes" of V2, rather than the actual words of V2, then something smells funky. But then, I present to you another item from their gift shop:
"A new booklet of devotions to Saint Jude has been written and prepared in accord with the mind and wishes of Vatican Council II. This booklet is available through the Shrine."
Sure enough, I looked in the Book of Blessings, and under the section dealing with the "blessing of food or drink or other elements connected with devotion". Paragraph 1795 gives an assortment of blessings, and among them is a blessing for oil which says, "May all who use this oil (in honor of Saint N.) be blessed with health of mind and body."
So apparently a clergyman can bless oil for use of anointing in honor of any saint you want. I never knew that.
