[P.O.E.]

Only one I have a question about:

Mass can never be celebrated "in a temple or sacred place of any non-Christian religion."

I can't think of any better way to consecrate a place. Or are they saying the building has to be blessed somehow first?

The way I understand it is for a building to be considered a sacred place (in which to celebrate Mass regularly) it must be consecrated. Definitely to be a cathedral. It is possible to have a special occasion Mass in another place, but it cannot be a building of worship for any other faith.
