During the first 17 centuries of our Common Era, the reliability of the Gospels was never seriously questioned. In the 19th century and beyond, some academics have questioned the traditional view of the Gospels as being inspired by God and have instead suggested that they were written by human authors who were attempting to convey their own perspectives and interpretations of the life and teachings of Jesus.
The reliability of the Gospels has long been questioned because of pseudo-scholarship. Were the Gospel writers plagiarists? Did the synoptic Gospel (Matthew, Mark & Luke) writers merely copy from one another? Is there a document called Q? Was the Gospel of Mark written first? Are the Gospels authentic and reliable?
