“Body and soul, it taught, were one and jointly responsible for sin, therefore jointly punishable. This became an important distinction between Christianity and Judaism. The Christian idea that, by weakening the body through mortification and fasting, you strengthened the soul, was anathema to Jews. They had ascetic sects as late as the first century AD, but once rabbinical Judaism established its dominance, the Jews turned their backs forever on monasticism, hermitry and asceticism. Public fasts might be commanded as symbols of public atonement, but private fasts were sinful and forbidden. Abstaining from wine, as the Nazarites did, was sinful, for it was rejecting the gifts God has provided for man’s necessities. Vegetarianism was rarely encouraged.”
― Paul Johnson, History of the Jews
