For sure, it was probably written by a monk in the name of Paul (like a lot of scriptures), but it is suppose to be the first epistle of Paul to Timothy. Typically, the monks were addressing modern issues (like women preaching) as if they were written by these people. It is still officially considered Pauline, and all of that is trash in my book.
Pretty awesome book on the subject of who wrote the bible, if you haven't read this one already.
Not true. Having many ancient sources is the reason we know how much they differ from each other. You're right about the typos and such, but you're also ignoring the major issues like fake books written under someone's name (many of Paul's current letters in today's bibles are proven to be written by people claiming to be him). Also people at the time tried to insert texts to support their views because the views did not have solid grounds in the texts at the time. For example, the Comma Johanneum. Check also some books about this issue like Bart Ehrman's Forged.
Christians might be ok with the levels of preserving for the Bible, but comparing that with the Old Testament and with the Quran, clearly it's the least preserved.
Any of the Bart D Ehrman books are worth reading. I am currently reading Forged.
The difference is that no modern scholar believes that Hercules actually existed. While the majority of modern scholars do believe that Jesus existed.
