Though intermarrying happened within all ethnic groups, tribes, etc. the Jews of the Middle Ages did not approve of it. They were very strict with their laws and customs and they did not think it enough to have faith in God but believed it crucially important to follow the Law of Moses. You can see how difficult a task that must have been when being up-rooted or forced to hide. Unable to openly teach religion, at times Jewish children grew up not knowing how to practice it. The old adage, use it or lose it, rang just as true during the Middle Ages for religion as it does today for any number of disciplines. What did happen though, when they had an opportunity to regroup, was that they tried their best to return to the old ways and the customs of the ancients.
