There is a difference between "truth" and "factual truth". The latter implies something that is verifiably objective, and I don't know of any reasonable religion that makes any such claim.
They all do, at least the major ones.
All religion openly claims a need for faith, belief, enlightenment, etc..
Sure, but they don't do so out of a sense of some fundamental doctrinal insecurity or doubt.
For example, Catholics don't call for faith in the divinity of Jesus because they would have doctrinal doubts about whether Jesus was divine or not.
Doctrianlly, the matter is settled, and Jesus is considered divine.
Faith (in the cognitive sense of acting positively despite feelings of uncertainty) is only called for when a particular person has doubts about the divinity of Jesus.
Regardless of the usual verbiage, how are any of these to be considered objective? The Absolute is necessarily an idealist abstraction, which cannot be verified in a finite, relative world.
I didn't get the impression that the major religions have a verificationist or experimental approach to what they teach. Ie., they don't make statements to the effect of "Let's test the doctrinal claims to see whether they are true or not."
IOW, religion doesn't seem to be about verification.
So how do you expect to adjudicate something which cannot be objectively examined? Should these religio-spiritual organizations just assume any claim of failure is de facto valid?
If a person attended church services, prayed and performed the prescribed practices, but continues to feel unsure about the doctrine and practices, then we can say they have failed.
For example, as another poster mentioned above, if a person attends Pentecostal services but doesn't feel the Holy Spirit, then such a person has failed.
These failures are evident: a person either begins or continues to feel unsure about the doctrine and practices; and/or the person does not display changes of thinking, feeling, speaking and acting that are otherwise the norm in said religious/spiritual organization.
And why should such failure, relying solely upon widely asserted personal subjectivity (faith, etc.), be any responsibly of any other group or persons?
Because asserting to know the Absolute Truth comes with absolute responsibility.
Of course, if we reduce religious/spiritual pursuits and conceive of them as merely subjective or culture-specific, then there is no point in talking about the Absolute Truth and the responsibility that would come with proclaiming to know it.
But suppose we take at face value religious/spiritual organizations and their claims to know the Absolute Truth - suppose we take them seriously.
What implications does that have? Like I said, on principle, someone proclaiming to know the Absolute Truth would also have absolute responsibility for anyone who hears said person.
Seems the possibility for fraud would quickly leave any such organization committing more time and resources to this than its original purpose. Perhaps that's your intent.
If they really know the Absolute Truth, then there would be no danger of fraud or misuse of resources.
