I read an article on Challies Dot Com about the increasing influence of mysticism on Evangelicalism (http://www.challies.com/articles/the-boundaries-of-evangelicalism). The author is concerned about this influence, given that the two ought to be opposed.
I find the attempt to distinguish between Christianity and mysticism interesting, because one thing that becomes readily apparent when one studies Judaism is that Christianity is mysticism. That is, the topics that form the core of Christian belief are, in Judaism, the material of mysticism: heaven and hell, the nature of G-d, the nature of the soul, the Devil, the supernatural understanding of history. The idea of Jesus dying on the cross for sins is a mystical concept. So is the idea of becoming part of his body. And so is the idea of the trinity.
Core Judaism isn’t as worried about making sure your beliefs on hell, or the structure of G-d, or whatever, are correct. In Judaism, you don’t follow the Law so that you don’t go to hell. You follow the Law because you’re a Jew, and the Law is what Jews do. G-d founded the Jewish nation, yes, and you’re obeying Him by following the Law, yes, but at the end of the day, the Law is proscriptive. You’re supposed to do–why isn’t as important. (To be fair, due to the influence of Chassidism, this description isn’t entirely accurate.)
Christianity is mystical to its core. Its main concerns are the nature of G-d in the Trinity, the meaning of Jesus’s death on the cross (understood as the ultimate victory), and eternal reward or punishment in heaven or hell. As a whole, it rejects the idea of following the Law. Some parts (Protestantism) even reject the idea that doing anything has any importance. Everything happens via the vehicle of the mystical Grace of G-d for the purpose of the Glory of G-d, and the only proper goal of life is the understanding that everything that exists is only an emanation of that Grace. The goal is understanding, not action–that’s mysticism.
What’s really interesting is that for some reason (or reasons), much of Christianity has felt the need to see itself as non-mystical. Thus came the “canon law” of the Catholic Church, that tried to essentially become a new law-based religion while still rejecting Judaism. So also comes the article at the beginning, trying to strictly and logically define what is proper, based on rules and guidelines–including rules for the proper way to feel awe at a sunset! It is certainly a curious experiment: making a practical religion out of a mysticism.
