It is hard to think of a more important issue that has exerted a greater practical impact upon Christendom than the Church's treatment of unbelieving Jews during her 2,000 year history.
• How "justification by faith," the cornerstone of the Protestant Reformation?
• Or, how about the "legitimacy of using means to reach the heathen," the cornerstone of the Protestant missions movement?
• How about the continuing validity of spiritual gifts, that propelled pentecostalism from nothing to #3 place among Christian traditions in less than a century?

Three possible events that had far more impact on the life of Christianity than our (occasionally bad) manners towards the invited guests who spurned the invitation and crucified the inviter! And have since then been hardened in petulent unbelief by nearly two millenia of denial.

I thank God for my friends who are still enmeshed in soul-damning cults (mormonism, islam, judaism) even as I pray for their conversion and salvation. In fact, the founding pastor of my church was raised Jewish, then came to the ongoing party as a young man, and has been busily inviting others to join the fun ever since.

Judaism is not a cult. As distortions of other religions, mormonism and islam could be seen as cults. Judaism, on the other hand, pre-dated Christianity and is a valid religion in its own right. That doesn't even begin to address that it was instituted by God Himself.

I'm sure the author is talking about the murder, mayhem, and prejudice directed toward Jews....pogroms, holocausts, anti-Jewish laws, etc.

Those things you mention: justification, evangelization, and spirituality are not "practical" issues within Christianity. They are directly addressed, biblical, doctrinal issues. These are things that MUST be taught.

Persecution of Jews, on the other hand, is not a Christian doctrine.
