Truth is what is most true
Truth is what the most truths affirm about that truth
In the Jordan Peterson ‘true at the most levels’ sense
Truth, so far as we are capable of seeing, because God exists in inapproachable light
Truth in the lines-of-evidence sense
Truth is like light split through a prism
All truths trace back to a source truth
The source truth traces forward to constituent truths
Pilate asked Jesus this question but didn’t wait for the answer
But Jesus did not condemn him for asking, either
Asking what truth is, is a somewhat forbidden question, a faux pas of sorts, yet asking it and providing as truthful an answer as you can give can be very helpful assessing all truth claims.
