Half a town was up in arms because a Fundamentalist preacher came out loudly and publicly against the Catholic Church. What were local Catholics to do? In California's high desert, a small town was convulsed by the antics of an anti-Catholic preacher. Townsfolk were beginning to turn against one another. Local Catholics were at wit's end.

In public talks he railed against confession, the Virgin Mary, and the Catholic interpretation of the Bible and salvation.
