Mitt Romney’s choice of Paul Ryan as his vice-presidential candidate makes 2012 the first time in American history that a major party has run a ticket without a Protestant on it: Romney is a member of the Church of Jesus Christ of Latter-day Saints, and Ryan is a Roman Catholic. Have Mormons and Catholics always gotten along as well as the Republican running mates appear to?
No. The root of the conflict is doctrinal. The premise of the Book of Mormon is that the Bible is a corrupt and incomplete account of God’s revelation—an implicit criticism of Catholic doctrine. The Book of Mormon also makes reference to an evil “church which is most abominable above all other churches,” described more colorfully as “the mother of harlots.” Though the Book of Mormon does not identify this evil institution as the Catholic Church, many Mormons have believed the two to be one and the same since the publication of the Book of Mormon in 1830.
