From a reader…
A former parishioner of mine asked me to come and bless/pray/cleanse the Masonic Temple he just purchased at auction. I said I’d research and prepare and get back to him with a date to do so.
I’ve reviewed the prayers for a person or family member who wishes to renounce all things Masonic but what about the temple itself?
If burning the place isn’t an option, then ask for permission from the bishop to say “Exorcism of Place”. It’s a useful appendix in the new rite, recently published (and the only useful part in that book).
There are several exorcisms of place in Fr. Ripperger’s book HERE.
A priest can enthrone the Sacred Heart there and say a Mass of the Sacred Heart, preferably on a first Friday (but any liturgically free day would be fine).
The new owner should pray his Rosary there frequently and track any wacky stuff that might happen. If he doesn’t notice anything, great. If he does, the priest can come back and do some more minor exorcisms.
