Just a friendly reminder that the main (in fact, sole, as far as I know) source for the "Enthronement of Lucifer Ceremony" story is the Irish shabbos goy Judas Malachi Martin, author of The Pilgrim, and the man who boasted right up to the end of his life that "no one had done more for Catholic-Jєωιѕн relations" than he.
Fantastical, lurid tales like this (and the ever-lurid philo-semitic Mr. Martin made considerable money weaving many such tales in his later years) serve one purpose: to distract from the much more prosaic truth: that the Church was subverted not by a spooky cabal of Laveyan Satanists, but by Jєωs and their Modernist Puppets (Mr. Martin being not least among this latter category).
