With all due respect, no it doesn’t. I agree that it can be corny, and I certainly don’t encourage it. But, the laity DO exercise the baptismal priesthood. JMHO, but I really believe a true and good desire among Catholics to affirm the ministerial priesthood, in some sense has us swing the pendulum back the other direction. It’s what I see with respect to Charismatics. Charismatic Catholics are among the most faithful that I know, but for some reason, the spirituality has been “black balled” by people who are otherwise orthodox Catholics. That’s a different topic for a different day, I know, but I think it’s related. Certainly, the laity are not ordained and can’t bless in the same way that an ordained cleric can. However, they certainly can bless by virtue of their baptismal priesthood. Many bless their children all the time. The rite of baptism even calls for parents and godparents to make the sign of the cross on the forehead of their child.
Again, I don’t encourage this practice in my parish. But, is it a hill I’m willing to die on as a priest? Certainly not. I also would not make the comparison used in this thread. One is a group of people exercising (even if inappropriately) their baptismal priesthood. One was a group responsible for the murder of over 6 million people. Even if the gestures look the same, the comparison is not prudent.
