I don't see why any president has to talk about his belief in God.

If you believe in what I do, which is secular humanism, I would find it extremely difficult to live with someone - not to love someone - but to live with somebody and build a life of someone who disagreed with me on something so fundamental.

Atheism is not a religion. One of the things, in fact, that atheism lacks are the kinds of rituals that religion does provide and I would be the first to say that.

The biggest religious wars and persecutions in history occur when religions, each claiming their own absolute truths, come into conflict.

There could be no more powerful argument against mixing religion and government than the success of independent African American churches in placing racial segregation and discrimination on a reluctant nation's social agenda. Would black churches have been able to take the lead in the struggle had they been dependent on funds doled out for 'faith-based initiatives' . . . ?

Throughout the three decades preceding the Civil War, the anticlerical ethos of the radical abolitionists was used against them by religious opponents of emancipation, who . . . even described abolitionism itself as an atheist plot.
