The dates that scholars have placed on the letters cause a lot of misunderstanding. I will tell you now, that I do not study much outside of the bible - like how the scholars came up with these dates. But from reading the bible, I do not accept them. There is no way that Revelation was written as late as 70-100AD. You can try to persuade me otherwise, but you will be more successful (if you are right) if you use the bible to do it. Again, I have done some research outside of the bible, but I don't put a lot into it because I do not trust the record of uninspired men - unless of course they agree with scripture.
