If you were trying to come up with a definition of misplaced intellectual arrogance, you could not do better than having the planet’s most famous atheist issuing diktats on who does and doesn’t count as a proper Christian. Prof Dawkins then announced, triumphantly, that an “astonishing number [of Christians] couldn’t identify the first book in the New Testament”.

Fraser: Richard, if I said to you what is the full title of The Origin Of Species, I’m sure you could tell me that.

Dawkins: Yes I could.

Fraser: Go on then.

Dawkins: On the Origin of Species…Uh…With, oh, God, On the Origin of Species. There is a sub-title with respect to the preservation of favoured races in the struggle for life.

It was a golden minute of radio. But as well as being hilarious, it was hugely symbolic. In The Daily Telegraph yesterday, Baroness Warsi highlighted the militant secularism on the march in Britain. But as Dr Fraser revealed, the atheist army is led by an embarrassingly feeble general. The arrogance and intolerance of the atheists, exemplified by Prof Dawkins, is their Achilles’ heel.

Here’s a sign of Dawkins’ arrogance, also from this column:

The statistics purport to show that most people who identify themselves as Christian turn out, when questioned on what they actually think, to be “overwhelmingly secular in their attitudes on issues ranging from gay rights to religion in public life”. Dawkins’s conclusion is that these self-identified Christians are “not really Christian at all”.

So: Dawkins declares who is and isn’t a Christian. If a Christian believed the things Dawkins says Christians believe, then they are, in Dawkins’ view, fools. But if they don’t believe what Dawkins says they should believe, then they aren’t really Christians. There’s no way to win.
