Culture has changed over the past thousand years. Punishments were different. Treatment to different sexes and races were different. The bible is dated to fit the time of the past.
Q1: Should we relive what the (outdated morality) bible says?
If yes, Q1a: Then why are you (generally christians) not living it? e.g. stoning criminals
If no, Q1b: Then how do you define modern christianity? Should the bible's outdated teachings be thrown away and replaced?
