on one of the most fundamental levels, the old testament teaches an eye for an eye and a tooth for a tooth. the new testament teaches turn the other cheek. how can such a fundamental difference be something that a christian must accept both as infallible truth? does truth change? how?
but it's more than that core theological difference. the old testament has God killing people over and over again, or commanding them to die. see the story of noah where he killed the whole earth, or the time he turned a woman to stone for questioning where she was headed and looking back to her old lifei understand that it's plausible that the consequences of sin is death, which even the bible says and is as true a statement as they come. but it seems to again be in stark contrast to the God of the new testament. what's with this bipolar God of the new testament and the hippie God of the new testament? i realize even Jesus pointed out that the commandment and consequence of disrespecting ones parents is death, but how can such a difference be fundamentally compatible with each other? (i often wonder if jesus was being literal that that's the way the world is, or if he was saying 'even by this standard, the pharisees weren't being consistent with mercy')
but it's more than these broader frictions. the old testament says unclean food is ungodly, yet the new testament says nothing God has made clean is unclean. how should we accept that Jesus' death change something unclean to something clean? or the old testament says men with deformed penis' can't enter into the assembly of the lord, which sounds like they can't enter heaven. how did jesus' death make deformed penis' acceptable? and the context doesn't indicate this old testament verse was against self mutilation, but that any deformed penis was too much, even from a disability or injury. the best i can surmise, if these old testament verses are true... is that these are ceremonial laws, and ceremonial laws can change with a covenant change, assuming the covenant change was legit to begin with. it's kinda like how often cultural differences are legit changes in the bible, (why it says women can't lead or wear hats in church, even in the new testament, but everyone now accept as just cultural norms being changed) and not infallible differences being changed arbitrarily. ceremony and culture are both legit and reasonable ways of differentiating, but the theology for why the rules were the way they were to begin with, or how they can change, can still seem arbitrary and capricious, to use legal jargon.
we also have things that dont make sense theologically.
-the bible looks literal of the story of noah in the old testament, and the new testament treats the story literal too. i dont have time to list all the scientific discrepancies of that story, such as how there's a constant lineage of cultures everywhere and constant archeological evidence of no flood everywhere, yet supposedly God destroyed it all... and hid or changed the evidence? to me, when God performs a miracle like he does with phsyical healings even in this day and age, he supports the miracle with evidence and truth. (such as the congregation of the causes of the saints with the catholic church) the story of noah isn't supported by evidence, but contradicts it. maybe it wasn't meant to be taken literally or was a local event?
-i'll add more examples in the future.
