When is a Religious Belief Delusional?

[Amarok]

That is true. To the degree that a new doctrine or revelation is being introduced it should be viewed skeptically. That is why I admitted that the internal safe-guards include consistency with prior teachings and would add that this safeguard is more of a warning sign than a test. A new doctrine could be a further clarification of prior revelations and historically these have not always been accepted. That is why there are still religious Jews and why Christians do not convert to Islam.

Your last statement is false and the rest is just nonesense

I do not consider the practice of prayer, in and of itself, evidence of delusion. 

Nobody does 

The idea that there is a level of reality deeper (or higher depending on your perspective) and more fundamental that what is currently known does not seem on its face to be irrational. After that, it is more a difference of degree than of kind by which we evaluate its reasonableness.
