When is a Religious Belief Delusional?

[Neo-Scholastic]

History is a hard area for me to think about in these terms.  Confirmation bias is always in play.

Fair enough. It seems implausible to me that all the NT scholars, such as N. T. Wright, who do know history and remain Christians are suffering from delusions. It seems to me that a reasonable person, such as yourself, would be willing to condemn the incendiary rhetoric of those who claim all religious beliefs are delusions.

And yes, confirmation bias is indeed something everyone should guard themselves against, believers and skeptics alike.
