I was VERY surprised to see Roman Catholics cancelling Mass and not giving communion!
Glad to see you posting!
Quick comment on this: in our diocese, Mass hasn't been "canceled." Rather, the bishop has given a dispensation from the holy obligation to attend weekly Mass in light of the risks associated with this situation as a matter of conscience. I think some individual Masses have been suspended (our parish has, I think, 6 weekly mass times).
Choosing to honor - more or less - the .gov request for no more than 250 people together at a time.
In terms of communion, the bread will still be offered (in the hand, not directly into the mouth) but not the chalice. In our tradition, it is kinda either/or - both are Christ, so either one gets it done.
Totally agree with the general proposition that it is a matter of conscience.
