Is Buddhism a religion without God? In a recent article titled "America’s New Religions
" which is concerned with political fundamentalism, the respected American journalist Andrew Sullivan  makes a passing remark that "Buddhism’s genius is that it is a religion without God". How appropriate is that statement?

I think it's more a comment about other religions than about Buddhism, i.e. it's saying that:


Some people find other religions unsatisfactory
Part of that dissatisfaction is with religions' doctrines about God


As an aside I think that some of the same people may disparage, resist, or ignore elements of Buddhism which say seem supernatural or requiring faith, including e.g. rebirth, karma, psychic powers, other realms.

Some people find a lack of religion unsatisfactory too, e.g.  that might imply immorality or what people disparage as moral relativism, and various other missing doctrines.

Conversely I don't think it's especially Buddhism's being without God that is its genius -- I think it's its being beneficial, practical, perhaps humanistic, offering hope, and so on.

Actually maybe "hope" isn't a standard Buddhist doctrine (i.e. "faith, hope, and charity" are overtly Christian, rather, and part of Buddhism may be to lose unwarranted hope in the wrong sort of thing, to become disenchanted) -- instead Buddhism might say something more like this about its own doctrine, i.e. that it is "visible in this life", "timeless", "conducive (to the cessation of suffering)", and "for the wise to know for themselves".

Of course that's not the only thing that Buddhism (e.g the Buddha) says about the Dhamma, e.g. another formula (i.e. description of it) is "good in the beginning, good in the middle, and good in the end" (see also e.g. this answer).
