Doctrine & Covenants (and Book of Nephi) on Catholicism, coming right up. Back at yah soon!
Good luck with that.
According to LDS scriptures, the “great and abominable church” and “whore of all the earth” refers to any organization that opposes the true Church of Jesus Christ. The Church does not teach or endorse the idea that these terms refer to any specific religion or organization. It is clear that in cases where past church authorities have modified this definition through speculation, that the First Presidency has firmly declared those speculations to be in error.
You won’t find Catholicism mentioned in either the Doctrine and Covenants or the Book of Mormon.
