...demolished, as I'm about to demonstrate.
Joseph smith and Mormonism can only flourish in seed that was planted by those who claim the Church fell away at some point.
These seed-planters would be the people you interviewed? That's who you said was making the claim. You seem to be making a bigger case for the existence of time travel than for the Protestant Reformation believing itself to be founded on the idea of a Great Apostasy.
Of course, the Scriptures only allow for a great apostasy right before the second coming and the end of the world. Even then, there will still be Christians alive and the true Faith held.
Excuse me, but I couldn't help noticing that you've dropped some of your seeds.
This was spoken in response to apostasy. We know from Matthew 24 that believers in Jesus Christ (not some false christ or false gospel) will not be deceived, will not fall away.
Matthew 24:24 (KJV)
24 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.
This is a contrary-to-fact condition. It is not possible to deceive the elect. But the deception will be great and will deceive those who think they are saved but who have believed a false gospel, or another savior/mediator and are relying on works and not the finished work of Jesus Christ on the cross.
The infallible word of God is clear:
1 Timothy 2:5-6 (KJV)
5 For there is one God, and one mediator between God and men, the man Christ Jesus; 6 Who gave himself a ransom for all, to be testified in due time.
One God. Not many gods.
One mediator, not another mediator (Joseph Smith, et al. Popes, and priests)
He was a ransom for all, not a select few. (His ransom only profits those who believe. "Believe on The Lord Jesus Christ and thou shall be saved" in response to e question: "What must I do to be saved?"--Acts 16:30,31)
