By Julia Meloni, Crisis Magazine - Today, as the fire of revolution burns in the Church, Dr. Taylor Marshall’s bracing, important new book Infiltration offers an illuminating “historical diagnosis” for our present ecclesial malaise. Adroitly weaving together papal documents, Marian apparitions, historical data, and original research into the mysterious center of gravity known as St. Gallen, Switzerland, Marshall convincingly shows that the sparks of Church crisis far predate both Pope Francis and Vatican II.
