I found this picture of one of the Resistance Mass locations -- can you say "try a bit harder"?
Maybe move the Nike sneakers into another room before Mass begins -- even if it's only temporary?
Maybe I'm just thorough, or maybe I just respect the Mass, but if that were my house (i.e., if I had the exact same circuмstances as the owner of that house) I would *at least* move some of the crap and knick-knacks out of the room (what's up with the sideways cookie jar?), even if only on a temporary basis i.e., during the Mass.
I assume there aren't many options for Mass in that location... because that house doesn't even seem to have any folding chairs! Come on, they're like $10 each at Home Depot. I got 10 used ones at a garage sale for $15.
I understand that this is the Catacombs, and that the Mass has value whatever the material circuмstances, etc. but I think we should at least try *our best* with what we have.
Let's not forget what manner of Divine Guest we are inviting into our homes...
And speaking of "the best with what we have" -- the owners of this house seem to have "ample means". One can buy a lot of statues, crucifixes, folding chairs, religious art, etc. with the price of that curio cabinet in the background (plus all its expensive contents). I can understand being poor, but I would never be simultaneously poor in religious art/sacramentals and rich in "material things". One word: Priorities.
A good Catholic will wear his Catholicism on his sleeve. It should be blatantly obvious to any visitor that you are Catholic, or there's a problem.
