Mass vs mass

Just finished reading "Angels and Demons" this afternoon. The climax seemed quite predictable after having read his other best-selling novel. However, it tickled my funny bones with the witty exchange of remarks of the two protagonists at the end of the book: "neutrinos have mass - "I didn't know they were Catholics."

It's hard to translate the term mass in Tagalog without recurring to and using the original English term. In Tagalog, "misa" would surely be amiss since it only means the religious celebration of the Eucharist.
