Some De Facto Satanist has been in past like in the present too members of the Freemasonry.
People like Cagliostro,Benjamin Franklin,Casanova ecc.
At your advice the Freemasonry can be compatible with the Satanism in the modern times?
Can one Freemason be also an Church of Satan Member or the two things are unconciliables?
Note which i speak about the Freemasonry of the Great Orient and not about the Illuminati.
Thank you

There are a number of CoS members who are also freemasons, yes.

A quick search would have produced this.
