Does Judaism require a leap of Faith?
Both Christianity and Islam require a leap of faith in order to believe, but this is an anathema to Judaism. We base our belief on a priori evidence and reason, in the same way that you believe the earth goes around the sun even though you have not personally witnessed it to be so.
Wow! I would say that is an oversimplification! An “anathema”? Last week on A Simple Jew’s blog there was an interesting debate between Rabbi Maroof and others along with some recap of historical answers to the question of whether reason or simple belief (i.e. although these words weren’t used, “a leap of faith”) was the best route to faith - evidence exists for both sides. I don’t think even those who opine that faith must be rooted in philosophical proof and evidence would compare religious belief with scientific claims like “the earth revolves around the sun” which can be empirically verified. 2+2=4 is an a priori truth that is justified based on reason; belief in G-d is a categorically different proposition. I personally find the assertion that faith can be grounded in pure rationalism to be overblown and fraught with its own dangers, as I previously wrote, but do believe religious belief is not counter-intuitive or unreasonable, as a Richard Dawkins or Sam Harris would claim. Exactly what the relationship between reason and belief is requires more discussion and more nuance than this simplistic answer provides.
