1. do they have evidence? not if the Scriptures are true, the Lord Jesus Christ Himself said the gates of hell will not prevail against it. further on, He promised to be with the Church ALWAYS, even til the end of the world. in addition, the Scriptures tell us the elect can not be fooled. finally, the Scriptures do teach there will be a great falling away from the Faith right before the end of the world. we are witnessing this falling away in our lifetime.
2. they did have a list of complaints and actually some were legitimate.
3. they did not add to the Scriptures like the Mormons, they subtracted from it. they removed 7 books from the OT that was in every Bible up until they came along in the 16th century.
'they' did?
And just WHEN did this event occur?
