So the God who made the prohibitions listed in the Old Testament is not the God of the Christians?
I wondered when someone would make this schoolboy error, Matt.
As has been discussed on at least two other threads recently, Jesus pointed out that he had come to fulfill the law. In other words, he had come - as God in human form - to make the law unnecessary by instigating a completely different approach to life (and before you make any comments about how unsuccessful that was, I will happily acknowledge that the church has often failed to live up to the standards Jesus set for us).
The Jewish people, for whom the original law was developed, remain under its jurisdiction for as long as they choose to ignore/dispute the Messiahship of Jesus. Therefore, it ios they who you ought to be addressing the question in the OP. In a sense, so does everyone else, since law only exists to control or manage human failing.
