In the Dark Ages there were few biblical texts so most medieval Christians could not look up scriptures and study the Bible for themselves. Most Christians during this time could not even read. So, church going laity and commoners understood the Bible only through the interpretation of the priests who, by the way, were for the most part doing everything possible to validate Christianity by demonizing Jews. If Judaism was still a valid religion, then Christianity (in the view of the theologians of the day) was invalid and therefore Jews and Judaism needed to be marginalized and defeated at any cost. There is no excuse for Antisemitism and anti-Judaism, but historically we can see how the uneducated Christian masses – having no Bibles and without the ability to read – could easily be deceived by anti-Jewish religious leaders and led astray.
