When Christians talk about Bible Studies for Wednesday night [or some other time they get together during the week], they do not ever learn the Old Testament in depth, and most of the time not even the New Testament except for the letters of Paul.  But that just goes to show that Christianity is really based on Paul. But that requires a belief that Paul understood the approach of Jesus better that any of the actual people that heard and saw him, and wrote down his teachings directly from first hand knowledge.  But if they want to learn Paul as an authority on Jesus, well so be it. But then, why is it that the ''Bible Studies''never include the Old Testament.

[One place where you can see the problem of not learning the Old Testament is when Christians try to take a verse from the Old Testament to show something is morally wrong, but ignore other verses. When they take the words of the Old Testament to be authoritative, they are depending on Jesus. When they ignore the Law of Moses, they depend on Paul. But this weakens their position . You can not have it both ways. Either the Law of Moses means what it  says, or it does not. I ask them to make up their minds.]

I might add here that the way I see morality of the Old Testament is that it is based on a synthesis of faith and reason. This is as we see in the Talmud where there is a great deal of discussion about how to understand the verses of the Law of Moses based on reason. Very few times is any discussion based on the idea that someone's opinion is halacha le'Moshe miSinai [a law to Moses from Sinai]. [There are a few places where it is considered that a law is halacha to Moses from Sinai. More often it is just clear that some things are in fact ''from the Torah''; e.g., things like the 39 types of work on the sabbath, or the many laws about the temple or marriage]. Rather all discussions are based on the idea of how can we reconcile seemingly contrary verses or later teachings that themselves were based on verses.

I hope that Christians start to learn the Old Testament in depth, not superficially. In fact, I recall that there was once a long time ago a father who read to his family a few chapters of the Bible at the dinner table every night until the family had finished the Bible several times over.
