Moses wrote the Torah. The New Testament was written mostly by the original disciples and Paul. The Koran was dictated to the prophet Mohammed. And in Islam, after that, Revelation was sealed. Meaning has not been finally captured.
Nothing is complete, and thus nothing is exempt from criticism. . .
At best, our symbols of communication are only referents and do not capsule reality. Events of word, deed, and nature are not sealed. . . They point always beyond themselves. More simply, truth is always evolving. We are always learning new truths, from science, from new religious writings, from nature, from events in the world.
