Does Everyone Have a Religion? Even Atheists?

Andrew Sullivan opines,

Everyone has a religion. It is, in fact, impossible not to have a religion if you are a human being. [. . .]

By religion, I mean something quite specific: a practice not a theory; a way of life that gives meaning, a meaning that cannot really be defended without recourse to some transcendent value, undying “Truth” or God (or gods).

Which is to say, even today’s atheists are expressing an attenuated form of religion.

Sully is not being specific enough. Consider Communist ideology. It is a practice, not just a theory. It is a way of life that gives meaning. It appeals to values that transcend the current situation such as the value of a classless society free of exploitation and alienation, a society with no need of the illusory consolations of religion, a society in which that opiate will not be needed because each will realize himself to the fullest in the here and now. Pie here below will obviate the hankering for pie in the sky. It is easy to see how so many millions in the 20th century could be recruited to the Communist cause. 

On Sully's definition, godless communism is a religion that rejects religion, which is to say: it is not a religion on any appropriate understanding of that term. Sully's definition is not specific enough, sullied as it is by being too broad.

Sullivan ought to say something sensible. I suggest the following. Human beings have very strong worldview needs.  Doxastic security needs, I call them. It is impossible not to have some worldview or other, tacit or explicit, unexamined or examined, uncritically imbibed from one's social environment or worked out for oneself. No human being lives, or can live, adoxastos, without beliefs, and in particular without action-guiding beliefs, beliefs that direct, as well as overarching beliefs that orient us in the scheme of things. Not even the Pyrrhonian can pull it off.

Now, in the genus worldview, distinguish two species: religious and non-religious.  Communism, being militantly atheistic and anti-religious, is a non-religious worldview. By contrast, Catholicism is a religious worldview.

At this point you ought to ask me for the specific difference.  If rationality is what distinguishes human from non-human animals,  what property or set of properties distinguishes religious from non-religious worldviews?  My answer in The Essence of Religion.

No good purpose is served by calling atheism a religion. It is a cheap piece of journalistic sloppiness too often maintained, too infrequently reflected upon.
