This question does open a big can of issues. You could have titled it,
"Reinvigorating after Sunday Mass"
or maybe more to the point,
“Reinvigorating Sunday Mass.”
Not that what is offered needs reinvigorating: it is, in itself, holy and complete. But many don’t know how (or why) to truly participate in the holiness and completeness present. I’m sorry to say, but I think many priest-celebrants as well, are distant from what they are in fact doing.
The essence of the Mass is “hidden” from so many of us - they/we do not see what is there in front of them.
Why? How to change this? That is the real issue, I think, the real question.
