Why is the New Testament repetitive?

Answer 1

What is most repetitive about the New Testament is the fact that there are four gospels, each telling somewhat the same story about Jesus of Nazareth. Matthew and Luke are known to be largely based on Mark, even to using almost exactly the same words in the original Greek language, so they are naturally very repetitive. Matthew and Luke also share a common sayings source, now known as the hypothetical 'Q' document, so once again there are many parables which, although not in Mark,are the same in Matthew and Luke.

You will find John's Gospel much less repetitive because, although it was inspired by Luke's Gospel, it varies much further from the originals.
