Continuation of the post:
As far as how the bible should be read. Mark Prophet(died in 73) wrote a 4 volumes book, the first of which is titled "The secret teachings of Jesus". If I remember correctly, he (along with others) believes that Jesus studied in the east between age 12 and 30. And He also believes that Jesus and the apostles had 2 SEPARATE teachings. One for the general populace, and the other is for the Elite only, hence the term "secret". The only one I read is the first volume. The way he breaks down a biblical passage is simply REMARKABLE. I mean regular people would look at a verse on superficial basis in general, but after considering his contexts, one finds him/herself literally stepping through secret doors within the NT to the "other side", It's absolutely STUNNING!!!!!!!! Anybody who is interested in Christ out there. I would strongly recommend they get hold of this book and read it. Simply fascinating.
Also Bart Ehrman, in "Misquoting Jesus", showed how they used to copy the bible back in the days. They had what they call " 'manual' copyists". Those copyists were illiterate. That means they could only draw letters. And according to him, they did not necessarily know what the words they copied meant. So if they missed a letter, a word or an entire line, chances are they wouldn't even notice as no commas, dots, paragraphs or chapters were known at the time. He goes into A Great detail about this. Another golden nugget to get hold of for the interested.
Thanks for the Marcion reference. I probably won't go looking for the Mark Prophet thing. It sounds like he made it up out of nothing. The idea of 2 teachings is right in the NT text though, so I don't he has anything "stunning". It's called "mystery cult". It's like a video game, you get tired of the one story, so they say, "but there's more, there's this other adventure that you are now ready for", to get you to buy the next version.
