The Bible as we know it was a collection of texts from ancient times, and it was amassed from a pool of literature even larger. It wasn't selected overnight. Lots of texts, some from authors who had other works selected for inclusion, were denied. Parts were added and dropped over hundreds of years. Maybe parts aught be dropped now? If God could change his mind a few dozen times 1500 years ago or so, surely he's not entirely set in stone now?Contradictions and bronze age justice aren't doing any good for the modern age, and only serve to inspire groups like these.
The pope needs to sit down and ask himself: Does God still believe this? And if he decides no, drop the passage. Should adulterers be stoned? If the uppercrust of Christian faith agree not, then remove the passage. The Bible is intended to educate the masses on everything a Christian aught believe. If this is the case, then all opportunities for cherrypicking between opposing statements aught be rectified. If a Christian aught not believe a passage, it shouldn't be included.
Every sect of christianity does this. That is why there are different sects. They all pick and choose what they want to believe from the available material, then they give it a name like "Baptist", "Protestant", "Lutheran", etc.
