Religion is faith. Faith is belief without evidence. Belief without evidence cannot be shared. Faith is a feeling. Love is also a feeling, but love makes no universal claims. Love is pure. The lover reports on his or her feelings and needs nothing more. Faith claims knowledge of a world we share but without evidence we can share. Feeling love is beautiful. Feeling the earth is 6,000 years old is stupid.
