Kiev in the Ukraine, the Message of Fatima Still Stands" - Father Malachi Martin during an interview with Bernard Janzen, New York City, 22 March 1997

Malachi Brendan Martin (23 July 1921 – 27 July 1999), also known under the pseudonym of Michael Serafian, was an Irish-born American Traditionalist Catholic priest, biblical archaeologist, exorcist, palaeographer, professor, and prolific writer on the Roman Catholic Church.

Ordained as a Jesuit priest, Martin became Professor of Palaeography at the Pontifical Biblical Institute in Rome. From 1958, he served as secretary to Cardinal Augustin Bea during preparations for the Second Vatican Council. Disillusioned by Vatican II, Martin asked to be released from certain aspects of his Jesuit vows in 1964 and moved to New York City.

Martin's 17 novels and non-fiction books were frequently critical of the Catholic hierarchy, who he believed had failed to act on what he called "the Third Prophecy" revealed by the Virgin Mary at Fátima. His works included The Scribal Character of The Dead Sea Scrolls (1958) and Hostage To The Devil (1976) which dealt with Satanism, demonic possession, and exorcism. The Final Conclave (1978) was a warning against Soviet espionage in the Vatican.
