Kostka, Jean (d. 1903)
Pseudonym of Jules Stanislas Doinel, a former Gnostic and
initiate of the 33rd degree. After being converted to Christianity,
Kostka claimed to reveal his diabolic adventures in the pages
of La Verité under the title ‘‘Lucifer démasqu钒 (Lucifer Unmasked).
He tells of diabolic happenings in the private chapel
of a lady, ‘‘Madame X,’’ who figures frequently in his pages (she
was thought to be the late countess of Caithness).
It seems probable from the evidence that ‘‘Jean Kostka’’
never came into personal contact with a satanic cult and that
his diabolic experiences were merely the imaginings of an intellectual
Satanist. Kostka’s revelations came in the same period
as the fake Satanist writings of ‘‘Léo Taxil’’ (Gabriel JogandPagès)
and seem to partake of the same contemporary antiMasonic
and anti-Semitic conspiracies.
Around 1890 Kostka founded the Universal Gnostic Church
in France and assumed the role of patriarch. He claimed consecration
directly from Jesus and later from two Bogomile bishops
who emerged during a Spiritualist séance. He in turn consecrated
other bishops and they perpetuated the Kostka
succession in a variety of small Gnostic churches.
