• Both claim to be the restoration of the “true gospel” that had been lost,
Does Islam claim to be a restoration of the true Christian gospel? Not to my knowledge.
• Both restorations involved visions,
Agree. Judaism and Christianity involve visions as well. So?
• Both restorations were assisted by an angel,
Yes. Angels made visitations in the founding of Christianity and in the Old Testament as well.
• New Holy Scriptures were revealed to man from a book that exists in heaven (or on Kolob as the case may be),
Ok I will give you this one.
• Both new scriptures claimed to be the perfect word of God,
Agree
• Multiple, inconsistent creation stories in the new revealed scripture,
I do not know about Islam but I think for Mormonism you are referring tot he Book of Moses as compared to the Book of Abraham?
• Practice of polygamy sanctioned at some point in both religions,
Yes
• Strict patriarchal authority in both religious and family life,
Yes
• Both religions are structured as effective theocracies,
Yes as was the Catholic Church for quite sometime.
• Both religions teach that Earth is to be cleansed by fire in the last days,
As does Christianity. Read Revelation.
• Both religions have sanctions against use of alcohol and tobacco,
Agreed.
• Both have ritualized fasting required by all adherents,
Yes and I believe fasting is part of many Christian sects and part of Judaism as well.
• Women relegated to secondary roles and subjected to the husband (or in Islam to any other male relative).
Ok. And in many Christian sects as well.
• Women encouraged to dress modestly, with sanctions against those who fail to do so.
Men are encouraged to dress modesty in Mormonism as well. What sanctions do LDS persons receive if they dress immodestly?
• Both the Book of Mormon and the Koran contain stories and/or extended near-verbatim passages from the Bible.
Yes. The New Testament also quotes the Old Testament.
• Both religions accept the Bible as scripture, but believe it to be corrupted in some ways and hold their revealed scriptures to be “more correct”.
Agree
• In both Islam and Mormonism, apostasy condemns one to hell, and in Islam apostasy can require blood atonement (that is, the death of the apostate).
I do not think Mormonism condemns apostasy to hell depending on how you define hell.
• Principle of blood atonement in Mormonism has analogs in Islam including death to apostates and the tradition of "honor killings". That is, there are certain sins that can only be atoned for by the shedding of blood. (Honor killings in Islam are usually visited upon young females.)
Mormon no longer teach blood atonement.
• Both of the revealed "perfect books" (Koran and Book of Mormon) were later revised to make them "more correct". Mohammad removed the "Satanic Verses" from the Koran, and more than a thousand changes have been made to the Book of Mormon since the original edition was printed.
Ok. But do some textual study on the Bible and you find the same thing.
• Both religions initially contained elements of polytheism, which were later removed (“Satanic Verses” from the Koran) or de-emphasized or denied such as man-to-God and Adam-God principles in Mormonism.
ok.
• Both religions have multiple heavens. There are 7 in Islam and 3 (plus additional degrees), in Mormonism, where men can be accorded multiple wives (and / or concubines in Islam).
Agree
• Both religions were divided into two or more sects by disagreements over whether the right to lead the religion (succession) should be inherited, or when new leaders tried to reform or update the basic tenets of the religion.
Yes and how many Christian sects today.
• Belief in the existence of "immortalized" or "translated" beings (The Three Nephites in Mormonism and the Immortal Imam in Islam), who still walk the earth waiting to be of assistance to the faithful in some future time of crisis.
Ok
• Both borrowed from paganism/polytheism. Muhammad incorporated that polytheistic moon god called "Allah" and "Allah's three daughters" into Islam. Basically Muhammad chose Allah from within 350 known gods that were worshipped in Arabia and proclaimed the moon god to be the greatest and only God. Joseph Smith borrowed from the Masons and other magic system
And Christianity adopted many pagen practices and holidays as well.
•
Both claimed to be uneducated / illiterate and used this fact as proof (evidence) their book was inspired.
Yes and Jesus was a carpenter and Peter a fisherman.
• Both claimed the Bible, though originally inspired, was lost, altered, corrupted and unreliable.
ok
• As a matter of record, Joseph Smith and Muhammad both had multiple wives and mistresses / concubines.
Can anyone come up with as many similarities between Mormonism and Orthodox Christianity?
Yes many. But it is late.
Really your comparison is mostly simplistic and forced. As noted many of your similarities are also found in historical Christianity and Judaism as well. Personally I think it is ridiculous to argue that Mormonism is more like Islam for one main reaosn. Mormonism believes Jesus is the Christ and the Son of God. It believes he died for our sins and was resurrected. Sure there are differences in how Mormonism views the nature of God as compared to orthodox christianity. But all the same, Jesus is God and one at least in purpose with the Father. Islam ha nothing like that.
