You can find his article here. It is well worth the read, and has many interesting points and thoughts to ponder over.
".... those who have an unquestioning faith in the correctness of the moral teachings of their religion are a problem: If they haven't conscientiously considered, on their own, whether their pastors or priests or rabbis or imams are worthy of such delegated authority over their lives, then they are taking a personally immoral stand.
That is perhaps the most shocking implication of my inquiry into the role religion plays in our lives, and I do not shrink from it, even though it may offend many who think of themselves as deeply moral. It is commonly supposed that it is entirely exemplary to adopt the moral teachings of one's own religion without question because — to put it simply — it is the word of God (as interpreted, always, by the specialists to whom one has delegated authority). I am urging, on the contrary, that anybody who professes that a particular point of moral conviction is not discussable, not debatable, not negotiable, simply because it is the word of God, or because the Bible says so, or because "that is what all Muslims (Hindus, Sikhs...) believe, and I am a Muslim (Hindu, Sikh...)" should be seen to be making it impossible for the rest of us to take their views seriously, excusing themselves from the moral conversation, inadvertently acknowledging that their own views are not conscientiously maintained and deserve no further hearing."
