Jesus Christ is fully capable of revealing his gospel to anyone he chooses. Even Joseph Smith. How is he a scourge on well-meaning people?????
Jesus Christ has "already" revealed His gospel to "everyone"...........and that revelation occured in the 1st century A.D., not in the early 19th century.
The Apostle of Christ confirms the fact that mankind has been given "everything" that pertains to LIFE and GODLINESS, "According to His (Jesus Christ) devine power has given unto us ALL THINGS that pertain unto life and godliness.........through the knowledge of Him that has called us to glory and viture:" -- 2 Peter 1:3
Next we find the Holy Spirit Inspired author of the book of Jude declare that the saints have "once delivered the faith" (Christian Faith) to the saints (at the time this book/epistle was being written). -- Jude 3
What more could Joseph Smith deliver as far as the faith of Christianity is concerned when the Holy Scriptures describe this faith as having been delivered by the saints (of the 1st century)..........ONCE with the Apostle Peter confirming that mankind had been given "ALL THINGS" (in the 1st century) that pertains to LIFE and GODLINESS?
No where is there a promise made that NEW REVELATIONS would be required for mankind to come to the knowledge of the Truth as God desires.........also note that that the Apostle of Christ explains that there is ONE "MEDEATOR" between God and mankind, and that Man is Jesus Christ (1 Tim. 2:1-5)........not Joseph Smith, not Muhammad, not the Pope, nor any other supposed other medeator that denies the Gospel as presented to all men by the Apostles of Christ in the first century.....in fact there is a CURSE placed on anyone that attempts to teach any other gospel than that which was delivered by the Holy Ghost inspired Apostles of Christ..............
"As we (the Apostles of Christ such as Paul) said before, and I now say again; if any man preach any other gospel unto you than that Ye (Christians of the 1st century) have received, let him be accursed." -- Gal. 1:9
Then you have some attempting to declare that Paul was not actually an Apostle of Christ and His teachings through his epistles are not actually considered HOLY SCRIPTURE..........but the Apostle Peter (who was given the keys to the kingdom of Christ...Christ's church here on earth (Matthew 16) in having Peter's words be bound in heaven and on earth)....declares that Paul was an Apostle, lacking nothing and compared Paul's teachings as HOLY SCRIPTURE.....that some who are unlearned struggle with unto their own destruction.
"............and regard the patience of our Lord as salvation, just as also our beloved brother Paul, according to the wisdom given him (Holy Ghost inspired), wrote to you; as also in all his letters, speaking in them of these things, in which there are some things that are hard to understand; which the untaught and UNSTABLE distort..........AS THEY DO ALSO THE REST OF THE SCRIPTURES (Peter compares Paul's teachings with other scripture.....meaning Peter consideres Paul's letters as Scripture......) TO THEIR OWN DESTRUCTION." -- 2 Peter 3:15-16
