What should I do, as a regular member of the congregation, if I suspect there is a Satanist attending our Masses and taking Communion?
The background is this:
There is a person that was masquerading as a "bishop" and saying "Mass" on Saturdays in a little chapel in our summer home community. I noticed a couple of irregularities in how the Mass was being performed by him and heard some refer to him as Monsignor and some as Bishop. I asked him directly what his title was and he replied, "Bishop."
I then looked him up on Google and found his web page where he professes to be an ordained Western Orthodox priest, as well as a psychic medium. I notified the chancery of our diocese and they did an investigation and notified all the parishes that he is not validly ordained and Catholics should not attend his services.
This past Sunday my wife said she saw him sitting in the last row of our home church. I was sitting with the choir up front and didn't see him but my wife said he left right after Communion. My fear is that he may be a Satanist and is attending Mass in order to steal a validly confected host.
