I attend Catholic Mass and read the Bible regularly, but I'm not a Christian generally or a Catholic specifically.I attend Shabbat services and Torah class regularly along with a number of nontheists. It is interesting to see mball speak so confidently about areas in which he is clearly and thoroughly ignorant.
Personally, I tend to go by a person's own definition of religion: in my mind, if a person claims to be Christian, that's good enough for me; if a person claims to be Muslim, then fine - he or she is a Muslim. I'm not in a position to judge the quality of a person's religious faith or practice.
When it comes to Judaism, though, does the label apply solely to a religion? If someone says "I am a Jew", does this automatically have a religious connotation?
To look at it another way, would you be able to find two people who would both say that they are Jews, but both acknowledge that they follow different religions? Would you be able to find someone who says both that he is a Jew and that he follows no religion?
You gave a definition of religion in terms of "ultimate concern"; based on it, what perspective do you have on how to judge the line where one religion ends and another begins?What this conversation once again makes me think is that religious liberalism has become so marginalized in this society that people don't even know it exists. People have accepted the conservative doctrine that religion must be the adherence to certain beliefs and/or practices (or else one is not x) and continue to accept this doctrine even as they claim to reject the authority of the religious conservatives.
