Christians lumped Islam with Catholicism and Mormonism as rival heretical faiths

Evidence

Elsewhere, Williams wrote of his anticipation that the destruction of Islam and Catholicism would coincide, along with the mass conversion of the Jews, with the apocalypse. … In 1912, Bruce Kinney wrote Mormonism: The Islam of America , the book’s title stemming from the perceived similarities between the two religions in terms of topics such as polygamy and ideas on heaven. The resemblance was not intended to be a salutary one, as the book, written by a former superintendent of Baptist missions in Utah, dealt with “the Mormon problem.” — Carl W.

Categorization

• XREF: Shows Islam featuring in a single eschatological cluster alongside Catholicism, Mormonism, and Judaism — applicable to the ‘differences that make for hatred’ pattern from Christian-immodesty moral panics.
• CANDY: A 1912 Baptist book literally titled ‘Mormonism: The Islam of America’ is a tweetable oddity.
