I've nearly sorted everything. As for Hebrews now. Why is the letter without authorship. It is unlikely to have lost the name by accident. To the point people say Priscilla wrote it and her name removed because she's a woman but there's problems with that idea. I see the main context here:
"Know ye that the brother Timotheus is released, with whom, if he may come more shortly, I will see you."
This person was clearly writing to someone or people, you don't just send a letter those days with no name and only this for context outside the sermon.
60 AD: Paul and Timothy are under house arrest in Rome.
61 AD: Paul and Timothy don't mention being prisoners. And they are with Luke and Demas now.
AAAAH I just thought about it while typing this. I know what happened.
Demas was never mentioned in Acts. Paul and Timothy go to Rome. Luke implies he was there with them.
Demas is mentioned three times and look at the evolution.
60 AD " Markus, Aristarchus, Demas, Lukas, my fellow-workmen!"
61 AD "Salute you doth Lukas, the beloved physician, and Demas;"
64 AD "For Demas hath forsaken me, having loved this present world, and is departed unto Thessalonica; Crescens to Galatia, Titus unto Dalmatia."
"Luke the beloved... and Demas." and then a few years later Paul has no good words.
Acts is a very optimistic book which is why if it was written after Paul's death it wouln't mention his death plus the patron he wrote to may have already known and wanted more info after hearing of Paul's death.
Being optimistic I think Luke snubbed Demas from any mention in acts because of what he did.
"ooh it's not like everyone gets mentioned there's so many peolple, what about this Aristarchus character mentioned in Paul's letters huh!?" Oh but Aristarchus is mentioned in Acts, three times despite never doing anything, just mentioned as being there.
So is it possible Luke didn't want to mention Demas on purpose because of his actions Paul alludes to.
AND IS IT POSSIBLE that the name of the author of Hebrews was removed because it was..Demas. *lightning strike* dun dun dun.
Demas went to Rome to retrieve Timothy, while at Rome he wrote Hebrews. He didn't mention Paul because he didn't care about him. Unlike every other Paul letter Hebrews addresses no churches or people it claims no authority makes no acusations.
Demas' name was removed because he went apostate. Well at least he abandoned Paul and who knows. There's a few other things but it's just a silly theory that came suddenly, other people have probably thought about it I don't know.
I do know I'll put Hebrews as 61 AD and at this point I think looking at all the arguments I have sorted out the New Testament book timeline well enough and I think it is much better when you read them in that order.
