To Catholics and other Christian believers, there are only four authentic gospels of Jesus Christ—those written by the evangelists Mark, Matthew, Luke and John. Almost everything we know about the life and teachings of Jesus comes from these four sources.

Even well-known historians who lived in the time of Jesus, such as Eusebius and Tacitus, hardly mentioned him in their writings. That’s rather strange, considering the numerous miracles Jesus was said to have performed during his public life.

“These Christians are now called Gnostics, from the Greek ‘gnosis,’ usually translated as ‘knowledge.’ As the Gnostics use the term, we could translate it as ‘insight,’ for gnosis involves an intuitive process of knowing oneself… To know oneself, at the deeper level, is simultaneously to know God.”
