Rene Guenon's explication of the principles of an interior understanding of sacred forms has established his reputation in the West as the master theorist of esoterism. But till now his doctrine has not been the focus of thorough study in Christian circles, and this has had serious consequences. Guenonian Esoterism and Christian Mystery is the first major work to combine an analysis of Guenon's ideas about esoterism with a critical examination of their application to Christianity in terms of data provided by Christianity itself. But to accomplish this, such data cannot simply be surveyed superficially-it must be known firsthand; hence the abundance of citations and references in this text. Such an approach not only lets us decide about certain issues, but may also help us rediscover an all too misunderstood facet of the revelation of Christ. Jean Borella taught philosophy at the University of Nancy until 1995. A Platonist by formation, he has been strongly influenced by Guenon and Eastern metaphysics. But his deepest inspiration derives from unceasing meditation on the Christian faith, which led him to undertake the present searching critique of 'Guenonian Christianity'. A religious philosopher, he strives to hear the reverberations awakened in human thought by revelation. "Rene Guenon was one of the great metaphysical minds of the last few centuries, and it was a great loss to the Catholic Church when he converted to Islam. Prof. Borella shows in this landmark study exactly where Guenon's work remains of perennial value for Christians, but also demonstrates the limitations and personal idiosyncrasies which led Guenon to distort some of the most important elements of Catholic and Orthodox doctrine. Prof. Borella's book may well stimulate the recovery of authentic metaphysics within the Church for which Guenon longed, but which he despaired of seeing in his lifetime." -Stratford Caldecott Editor, Second Spring, Director (UK) of the G.K.
