I’m unaware of anything that Joseph Smith ever said negative about Catholicism. I don’t think that there was even a Catholic church in his home town, of which he described the local sects as abominations (probably because of the doctrine of Calvinist predestination and its denial of free will, which was common back then). If you have any evidence of anticatholic writings in the 19th century, please enlighten me. I thought that Talmage and McConkie started it all.
And the LDS church forced McConkie to take out his anticatholic statements out of post-1st edition versions of his book.
From the tenor of some remarks here, some people here would feel more comfortable if Mormons were antiCatholic, but they aren’t. And most Catholics that I know (and most people I have ever met were Catholic!) recognize that the LDS people are Christians, and don’t have a problem with us. I’m sure you can find some weird LDS blogs with bigots, but like I said, the web brings out the weirdoes.
“The Roman Catholic, Greek, and Protestant church, is the great corrupt, ecclesiastical power, represented by great Babylon…” (Orson Pratt, Orson Pratt, Writings of an Apostle, “Divine Authenticity,” no.6, p.84).
“…all the priests who adhere to the sectarian religions of the day with all their followers, without one exception, receive their portion with the devil and his angels.” (The Elders Journal, Joseph Smith Jr., editor, vol.1, no.4, p.60)
“And any person who shall be so wicked as to receive a holy ordinance of the gospel from the ministers of any of these apostate churches will be sent down to hell with them, unless they repent of the unholy and impious act.” (Orson Pratt, OP-WA, “The Kingdom of God,” no.2, p.6)
“…all other churches are entirely destitute of all authority from God; and any person who recieves baptism or the Lord’s supper from their hands will highly offend God, for he looks upon them as the most corrupt people.” (Orson Pratt, The Seer, pg. 255)
“…the great apostate church as the anti-christ…This great antichrist…is the church of the devil.” (Apostle Bruce R. McConkie, Mormon Doctrine p.40)
“Both Catholics and Protestants are nothing less than the “whore of Babylon” whom the lord denounces by the mouth of John the Revelator as having corrupted all the earth by their fornications and wickedness.” (Pratt, The Seer, p.255)
“Brother Taylor has just said that the religions of the day were hatched in hell. The eggs were laid in hell, hatched on its borders, and then kicked on to the earth.” (Brigham Young, JD 6:176)
Brigham Young regarding the Christian view of Jesus Christ:
“You may hear the divines of the day extol the character of the Saviour, undertake to exhibit his true character before the people, and give an account of his origin…I have frequently thought of mules, which you know are half horse and half ***, when reflecting upon the representations made by those divines. I have heard sectarian priests undertake to tell the character of the Son of God, and they make him half of one species and half of another, and I could not avoid thinking at once of the mule, which is the most hateful creature that ever was made, I believe. You will excuse me, but I have thus thought many a time” (Journal of Discourses 4:217).
