I recently attended a community Torah study hosted by a Reform rabbi. As we were discussing the weekly Torah portion, many of those in attendance (Reform Jews) kept referring to "the men" who wrote the Torah.
As someone who believes in the concept of Torah mi-Sinai, I am at a loss as to how Reform faith works. If the Torah was written by men, even if inspired by G_d, then it is still a man-made document. For many, including myself, Maamad Har Sinai is a historically central event in Jewish history and the basis of Orthodox emunah. What then is the Reform concept of emunah based upon? In other words, is a human authored document the basis of their faith?
