where in the bible does it say that Jesus did not set the 12 over the others?
on what basis do you assert that Jesus did NOT set the 12 over others?
all available evidence, at least until the 16th century indicates that Jesus did set the 12 over others.
maybe you have some evidence to support your contention that christianity did not have a hierchical structure from its very beginnings.
why would you ignore the fact that Jesus gave special teachings and instructions to the 12? why ignore the fact that the 12 were hand-selected by Jesus?
are you suggesting that His selection of the 12 for specific and exclusive instruction had no specific meaning in tems of understanding and authority?
