If you had been more specific about specific statements you have in mind (besides some from Orson Pratt who wrote with a shrill pen and often didn’t bring context with what he was writing), then I could answer your questions. Joseph Smith didn’t single out the Catholic church, to my knowledge. He did say that restored authority was important, especially for such ordinances as the gift of the Holy Ghost and temple marriages and sealing. He also wrote that Heavenly Father is “more benevolent” in how He will treat humankind in their judgment, when all is said and done, than most people have any idea of.
There were many, including Joseph Smith, which you would then say he was repeating what God told him. Namely, the Church I built is a failure and I, God, need you, Joseph Smith to restore it.
There is the BoM itself, of course, supposedly the word of God. God calling His Own Church, the One He Created with His Son and the One the Holy Spirit was to stay with, the whore of the earth.
Joseph Smith: “What is it that inspires professors of Christianity generally with a hope of salvation? It is that smooth, sophisticated influence of the devil, by which he deceives the whole world.”
LeGrand Richards, (I know, if a Mormon doesn’t like what he reads from another they say they were not acting in the name of the church), however I know his book stands on the shelves of my Mormon friends.
Brigham Young, John Taylor, Bruce R. McConkie, Orson Pratt, Joseph Smith, Spencer W.Kimball, Ezra Taft Benson, George Q. Cannon, Heber C. Kimball, Wilford Woodruff, Joseph Fielding Smith.
The problem one faces with studying Joseph Smith’s teachings, is that since he was pointing toward exaltation as the goal, then anything less than that is not something he would write encouraging words about. An apostle would not equivocate about the goal of the gospel being to become like Christ, because that is what their witness to the world is–that such is possible, and is promised to those who love Him with all their heart and do His will, including learning to have faith in Him, hope in His redemption and grace, and love for everyone around them and for all the world.
Parker, JS was trying to discredit other churches,including the One Jesus Christ Himself started, to prove that he was needed, and therefore a prophet to be followed. And many fell away from him and his teachings and today the Mormon church is backing away from him and BY and many others.
I do think the 19th century had more religious fervor generally, and certainly more people knowledgeable about the Bible and its language, than people generally today, so when people hear some “strong” language today in words written or spoken in the 19th century, they aren’t familiar that what they are reading is language straight from the Bible.
I agree that people today are offended by things that their parents and grandparents were taught!
Best wishes, again, to you and your family.
