And frankly, the postmodern culture adds to this a disservice by selling the public on the idea that you are the maker of your own truth. Because if that is so, then there can never be a genuine exchange of ideas, simply because you can never get outside of your self-administered cultural context. And without a meaningful exchange of ideas, communication breaks down and relationships fail.
(I have a lot to say on that last point but I'll save it for later.)
Being raised in a strict Christian faith I was definitely taught, to the point that it was unquestionable, that the only "objective truth" was God and what Christianity teaches. It feels so very good at this point in my life to know that there are many "objective truths" that are irreligious.
