What do LDS think about other religious leaders who receive direct revelations and have written scriptures?

Take, for example, the Rev. Sun Myung Moon.

[1]

Here are the similarities I find between the life and teachings of Rev. Moon and Joseph Smith:

Vision - “Moon claims that in 1936, when he was 16, Jesus Christ appeared to him on Easter morning on a mountainside in Northwestern Korea and told him that God had chosen him for the mission of establishing the Kingdom of Heaven on Earth, a mission that Christ had only begun. Christ supposedly told Moon that he would be ‘the completer of man’s salvation by being the Second Coming of Christ.’”

Involvement With the Occult - “Moon admits communicating with familiar spirits by means of séances. [It is a well-known fact that Moon has participated in séances conducted by a spirit transmedium named Arthur Ford (a famous Philadelphian necromancer).”

Source of Authority - Moon teaches that "the Bible is not the truth itself, but a textbook teaching the truth.  Moon's 536-page spiritual manifesto, Divine Principle (1957), is considered to be their scriptures (supposedly revealed directly to Moon by Jesus Christ), along with the Bible.  Divine Principle is considered to be the 'third testament' of the Bible, and superior to the Bible.  They also believe in continuing revelation.  Moon claims to have received new revelations from God; i.e., 'I spoke with Jesus Christ in the spirit world. And I also spoke with John the Baptist. This is my authority.' [HJB] Even Divine Principle is not the complete truth. ‘The Divine Principle revealed in this book is only part of the new truth. … as time goes on, deeper parts of the truth will be continually revealed’ (Unification Theology, p. 16).

Ultimately, Moon’s interpretations and teachings are considered to be the final and absolute source of authority. Moon’s teachings warn church members that life on earth is a continuous battle between good and evil — where they are the Chosen People — and everyone outside of the ‘True Family,’ including their biological parents, may be agents of Satan. Any person harboring doubts about Moon is deemed to be allowing himself to be part of the work of Satan.”

Christianity - “God is now throwing Christianity away and is now establishing a new religion, and this new religion is the Unification Church.”

Target of Proselytizing - “All the Christians in the world are destined to be absorbed by our movement.”

Marriage Essential For Salvation - “Marriage is the most important means of establishing God’s kingdom on earth. Moon teaches that ‘God-centered families are the building blocks of a world of peace, stability, and love,’ and that only those who are married will be saved, or qualified, for the kingdom.”

Doctrines - (1) God: Rev. Moon denies the Biblical concept of the Trinity.  (2) Salvation: “Rev. Moon teaches “the ‘Law of Indemnity’ — that God’s children must pay for at least a part of their debt of sin before God will forgive them.  They believe a person earns his salvation through fasting, fund-raising, recruitment, and other such works.”  (3) Universalism: “Moonies teach that heaven is a realm of the spirit world and that hell is inconsequential because it will ‘pass away as heaven expands,’ and all mankind is redeemed.”

Insider Doctrines - “An outsider doctrine is presented to the general public or potential converts which is more palatable and likely to be accepted, while the insider doctrine, presented to members or those deep within a group — is something completely different. A classic example of this can be found in the Unification Church. It has long been a secret inner teaching within the Unification Church, passed on by word of mouth, that Jesus was an illegitimate child, conceived through Mary having sexual intercourse with Zachariah the father of John the Baptist”   (http://www.newcovpub.com/unification/examples.html)

Doing Good - The following is an excerpt from a sermon given by a member of the Unification Church found on www.unification.net.  This teaching is taken from an Exposition of the Divine Principle – Part II, Chapter 1, Section 3.4: “ I need to look at my attitude, motivation and purpose in every thought I think, every word I speak, every action I take, everything, everything, everything. In my every thought, word and deed, I need to check my attitude, motivation, and purpose. When I do things for the church, how come I get burned out? Well ask yourself, what’s your motivation? Are you doing it for God’s will, or for glory for yourself, for credit, for recognition? “Oh, I’m such a good person because I serve True Parents.” You really have to check your motivation in everything you do. If your motivation is impure, God cannot accept that offering. If you do it but you have a horrible attitude, “Oh, I’m serving God but I really don’t want to be here, ” then you had better not be there. There is no point. So we really have to purify ourselves and check ourselves moment by moment. Pray constantly to check our attitude, motivation and purpose in everything we think and feel and say and do. We are responsible for our feelings, we are responsible for our thoughts, for our actions and our words. I have to examine whether I am being unselfish and Godly, or whether I am being selfish and Satanic. To be able to distinguish clearly between good and evil in myself, I need God’s word. Father encourages us to read his words every day. Why? So that we can clearly know good from evil, and voluntarily choose the good.” (http://www.unification.net/damian/dja20021215.html)

Read the Book - Rev. Moon says, “How many times have you read the Divine Principle book? You have to constantly study and read this book every single day… If you happen to receive a spiritual revelation through reading a translated version of the Divine Principle book, it is far below the level of experience of those who are able to read the original text. In the future there will probably be thousands of different translations of the Divine Principle book. However, the original Korean language book is the root. This means that all of these various branches can be cut off someday and everyone must return to the original Divine Principle book in order to truly understand.” (http://www.tparents.org/Moon-Talks/moon-other/sm-dp.htm)

The following account suggests that the Unification Church applies the same test as Mormonism to discern the truth of the Divine Principle book:

“Not many years ago I was at the Unification Church headquarters in downtown Minneapolis meeting with a couple of members. We were discussing their sacred book Divine Principle. A young woman told me that if I read Divine Principle and prayed I would receive a burning in the bosom to show me that this great book was from God.” (Discerning Truth, Jay Howard)

Jesus said, “Many shall come in my name, saying, I am Christ; and shall deceive many…For there shall arise false Christs, and false prophets, and shall show great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.  Behold, I have told you before” (Matthew 24:5, 24-25).

Questions:

1)  Is this religion of God since it invites and entices to do good?  The Book of Mormon says, “That which is of God inviteth and enticeth to do good continually; wherefore, every thing which inviteth and enticeth to do good, and to love God, and to serve him, is inspired of God” (Moroni 7:15)

2)  Would the Holy Spirit reveal to someone that they should be a part of this religion?

3)  If you do not believe the Unification Church religion is of God, how do you know this?  Have you personally read and prayed about the Divine Principle to seek God’s answer on this matter?  If not, why not?

4)  If you did read the Divine Principle and you received the same revelation that you did concerning the Book of Mormon, would you join this religion?  Why or why not?
