I'd like add since it came up, comparatively on a philosophical Christianity is a solid as it can get. I do want to also say that I'm not of the belief that the bible in anyway contradicts its self. The old testament is largely an account telling of the many times people transgressed the laws of God, and how they suffered subsequently. A recurring theme is how the prophets were continually chosen and how eventually people would stray from God. So something that may be used out of context would be like saying "God allows or tells you to have slaves." This would be a good example of taking something out of context. There are indeed guidelines that teach you how you might treat a servant, but that does not really equal to out modern understanding of slavery. I'd add to that God did not tell people to have servants either, this would totally be a result of freewill. (it was Christian nations that would also put an end to servants while Muslims still practice it to this day) There are also themes of sexual violence and child sacrifice in the bible but it's pretty clear that the bible says they are not good things.
Since I glossed over it I want to go back to the Talmud briefly and then the Quran. Modern Judaism is not the same as it was before Christ. The Jewish people back the, while many did not, rejected Christ as the messiah and had him crucified via the Roman. Fun fact when the bible refers to the nation of "Israel" or "the new Israel" this is in reference to those who would come to be Christians, not to those who would rejects Christ as Jesus specifically foretold that the old temple would be destroyed. Modern Jews believe that Christ is burning in feces and that non Jews are like cattle. (just like Muslims) It's in their books if you really want more on that.
The "prophet" Mohammed came something like 600 years after Christ and claimed that he had received the world of God and would go on to make the absolute abominations of a religion called Islam. Making claims that Christ was not divine (like the Jewish people did) and that he did not really die on the cross. Islam also teaches you not to question the faith while Christianity encourages one to reflect upon and meditate on the word of God. Neat fact is that the bible actually had already addressed something like this. Galatians 1:8:"But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed".
I'd totally look into these things though if you are curious rather than just take my word for it. I used to be more than critical of Christianity until I came to terms with the fact that I didn't actually know as much as I thought about it.
