In a two-year correspondence with Malachi Martin, Wolfgang Smith broaches a wide spectrum of topics, to which Fr. Martin responds in a way that may surprise many readers. What stands at issue is the meaning of authentic Catholicity-of the universality of Catholic truth. Theologians have long been stymied and misled by what Malachi Martin refers to as an "intellectual impasse" that needs to be "deblocked." Martin and Smith agree on the necessity "to open doors and windows," not in the name of an aggiornamento, but for the very opposite reason: to rediscover an ancient wisdom, at once theological and cosmological.
