"We are all quite familiar with this idea, that the old Jewish priesthood was a mere symbol and that Christianity is the reality which it symbolized. It is important, however, to notice what an astonishing, even impudent, claim it must have seemed as long as the temple at Jerusalem was still standing. In the temple you saw real sacrifice being offered - real animals really had their throats cut and their actual flesh and blood were used in the ritual; in Christian assemblies a ceremony with wine and bits of bread was conducted. It must have been all but impossible to resist the conviction that the Jewish service was the reality and the Christian one a mere substitute - wine is so obviously a substitute for blood and bread for flesh! Yet the Christians had the audacity to maintain that it was the other way round - that their innocuous little ritual meal in private houses was the real sacrifice and that all the slaughtering, incense, music, and shouting in the temple was merely the shadow."
