…Paul wrote this letter both to encourage these people that are young in faith and to instruct them against heresies that had been introduced to them by Gnostics. The Gnostics were a mixture of Jewish legalism and Greek hidden knowledge seekers with a dab of Christianity on top. They majored in hidden knowledge for salvation that was only made known to a few. They didn’t believe that Jesus had a physical body but was an emanation that appeared to his disciples to reveal hidden knowledge. They also did not believe in the physical resurrection of Christ but saw it as a spiritual event.
