Here is a version of that meme, from Dawkins:
Well, science is not religion and it doesn't just come down to faith. Although it has many of religion's virtues, it has none of its vices. Science is based upon verifiable evidence. Religious faith not only lacks evidence, its independence from evidence is its pride and joy, shouted from the rooftops. Why else would Christians wax critical of doubting Thomas? The other apostles are held up to us as exemplars of virtue because faith was enough for them. Doubting Thomas, on the other hand, required evidence. Perhaps he should be the patron saint of scientists.
It seems to me that the existence of a book like Evidence that Demands a Verdict refutes this version of the meme. Christians do claim that they have evidence, the don't typically shout from the rooftops that they don't have any and it shouldn't matter. That doesn't mean that they might not have misunderstood the idea of evidence, or that there isn't a lot of popular fideism out there. Discussions here between Dawkins defenders and others have often involved the claim that Christians think they have evidence when they really don't, that to have evidence you have to have thus and so, and McDowell and those like him don't have that. But Dawkins isn't even saying that. This is either ignorance on a massive scale of what Christians have been saying, or intellectual dishonesty. Or since it's coming from and Oxford professor, both.
Here is Lewis on Doubting Thomas:
The saying "Blessed are those that have not seen and have believed" has nothing to do with our original assent to the Christian propositions. It was not addressed to a philosopher enquiring whether God exists. It was addressed to a man who already believed that, who already had long acquaintance with a particular Person, and evidence that that Person could do very odd things, and who then refused to believe one odd thing more, often predicted by that Person and vouched for by all his closest friends. It is a rebuke not to skepticism in the philosophic sense but to the psychological quality of being "suspicious." It says in effect, "You should have known me better." There are cases between man and man where we should all, in our different way, bless those who have not seen and have believed. Our relationship to those who trusted us only after we were proved innocent in court cannot be the same as our relation to those who trusted us all through."
