Why were some New Testament books disputed?

The process of recognizing the New Testament canon took some time. When it was originally written, the New Testament was not one compiled literary work but rather 27 different writings that circulated around the early church. As the church expanded, began dealing with false teachers and doctrines, and came under intense persecution, it became necessary to spell out the recognized limits of the New Testament canon. In the process, some books like Hebrews, James, or Revelation were disputed for a time but eventually recognized as canonical. Additionally, fraudulent books began to be written, claiming to be from one of the apostles or close associates of Jesus. Dan Brown popularized the idea in the DaVinci code that all of these writings had equal weight with the rest of the New Testament writings we have today, and that at the Council of Nicea in the 4th century, the church picked the books they liked and discarded the ones they didn't.
