Many do this at our parish, but it is the ONLY parish I’ve ever been to where anyone even cared enough to know they were supposed to do this (aside from what we consider to be our sister parish north of us - only these two). Most of the time I think folks just show up and go through the motions - by no fault of their own mind you - but only because they are never taught anything more from their priest than to shake hands at the sign of peace with AS MANY people as possible, and…
…ok - stopping there, I’m starting to sound nasty and uncharitable. :o But you get my drift.
We all need to get back to this level of reverence and respect for Christ. My goodness, what if He came to us tomorrow? Would we all just look the other way? Sometimes I do wonder because the vast majority of American Catholics are never taught anymore about their Faith - such a pity.
