A truth claim is an assertion held to be true in a religious belief system; however, it does not follow that the assertion can be proven true.
For example, a truth claim in Judaism is that only one God exists, while other religions are polytheistic.
Conflicting truth claims between different religions can be a cause of religious conflict.
The theory of truth claims has been advanced by John Hick.
