2Sara Di Diego = "This was the first instance of Jesus' public ministry, according to the book of Luke. Although this version of Luke says that Jesus opened the book of Isaiah, there was no such thing as a book of Scriptures in Jesus' time. Instead, there were many scrolls, each with a different book of the Old Testament.In fact, the Scriptures being a book was a Christian invention, that Jews eventually followed. This was due to the fact that since the New Testament refers to the Old Testament many times, and it is very hard to find a past passage with a scroll, a book was made. In addition, it was easier to spread the word with a book than a bunch of scrolls."
