Maybe someone here who is Christian can answer me a question I've been wondering about for a while now. There are quite a few laws written in the OT which we don't respect anymore, even fundamentalist Christians do not follow them anymore. For example, stoning people to death. Here a few specific examples: Mose 5th Book/Deuteronomium 21, 10-14: When you go to war and defeat your enemy, your soldiers may choose daughters of the defeated enemy and marry them. Or Mose 5th Book/Deuteronomium 22, 22-29: When a woman is raped within a city, she has to be stoned to death, because when nobody heard her crying for help, that obviously means she wanted it and thus it was adultery. I think we all, even Christians here, will agree that such laws are cruel and we don't respect them anymore today. But why is that? My first explanation would be to say "well, it's OT, but then came Jesus and the old law was changed". But now I find a problem: In Matthew 5, 17-20, Jesus explicitly says that he has not come to change the old law, but that the old law has to be respected and "not a single letter" will be changed of the old law. Can someone versed on theology help me out?
