Ok. Absolute values - unconditional values - are by definition not possible to prove using reason logic. The area of knowledge beyond reason/logic is religious. One needs to understand the terms here to continue; absolute = self-evident = inherent = intrinsic...
So these beliefs, in this example, beliefs about values, are beyond the sphere of reason/logic and in the sphere of religion.
Quick example: kindness is better than cruelty.
IF kindness has inherent value for you, has value all other things being equal, then this is a belief in the sphere of religion.
Perhaps kindness is not one of your religious beliefs. Maybe truth is. Or love. Or life.
Whatever you believe has intrinsic value, value all on its own, that is a religious belief.
It may even include why you get up in the morning. What your purpose in life is - as you believe it.
