Walter Ralston Martin

Walter Ralston Martin was an American Baptist Christian minister and author who founded the Christian Research Institute in 1960 as a parachurch ministry specializing as a clearing-house of information in both general Christian apologetics and in countercult apologetics. As the author of the influential The Kingdom of the Cults (1965), he has been dubbed by the conservative Christian columnist Michael J. McManus, the "godfather of the anti-cult movement".
