I say the Funeral Parlor is to blame for not having control of the guests. (About 200-300). Usually , chalice is on altar. It seems the problem is with the funeral parlor for not controlling the people. The priest should have quietly walked out and drove out of there.
From the different articles, it seems that the funeral parlor failed to do their job of crowd control.
Maybe the truth will come out with the Vortex.
