In answer to the op...yes the bible is a mass of contradictions because it is an amalgamation of ALL superstitions held at that point in time. Should one want to follow such an out moded set of belief systems is a personal matter. For me give me scepticism and science to inquire about pertinent issues regarding humanity and our place in this world/ galaxy.
