"The doctrine of reincarnation was repudiated only in A.D. 553, during the Second Council of Constantinople. Thus, the doctrine regarding the pre-existence of the soul and its continuous return to Earth was declared "heresy" by official Christendom only in the sixth century A.D. Until that time it was tolerated and accepted by those churchmen who were particularly close to the Gnostics. (8 October 1935)"
