What�s Wrong with Gnosticism?: “So what is Gnosticism? Without getting too intellectual or theological, Gnosticism basically indicates that the requirement of salvation is special knowledge from God, which they call, simply, knowledge. Although Gnostics admit that Jesus came to earth to save mankind, Gnostics believe He came to bring this special knowledge which would lead people to salvation. They did not believe that Jesus Christ actually lived and died as a fully human individual, nor that He died for the remission of our sins. Instead, they believe that He only appeared to be human, and that either an image of Him was crucified or that someone else was crucified, and the people of the time didn�t realize that they were crucifying the wrong person (imagine that!). “
