The information published from a Roman Catholic will be considerable different than that of a Protestant. In ancient times groups have claimed the knowledge of God. Gnostics and Mandeans, both these names mean knowledge as revealed by God. Knowledge of God should not have any boundaries or limitations. Archeological discoveries of documents written by the contemporaries of Jesus and His apostles should be considered.
Archeological discoveries are strong evidence and contribute to biblical updates and corrections.
Each individual has the final decision as to what is acceptable and intelligent discussion has a meaningful place. Christian history has considerable influence on what is consider a good source. If historians support a certain concept we should take it into consideration and adjust beliefs accordingly. Very few of our clergy keep up to date with this information. Down through the ages each teacher had to teach in a form appropriate to the intelligence and ideas of his hearers.
