It has recently surfaced that the Sisters of Perpetual Indulgence (an extremely vile and blasphemous group), have been using (or will use)... the hall of a Catholic Church to host their events.
The Most Holy Redeemer Church in San Francisco has an address of 100 Diamond Street - the same address as that posted on the Craigslist posting. A call was placed to the Church to verify that the hall was being rented to this group. The secretary confirmed that such is the case.
Essentially, the Church is sponsoring this scandalous group that flagrantly mocks the Church and her servants.
I would strongly recommend you call the Archdiocese of San Francisco to let them know what you think about this (in a decent and moderate manner): 415 614 5500
