Reading today, I happened upon a passage that strikes me as very appropriate for the feast of Epiphany. From Exploring Reality: The Intertwining of Science and Religion by John Polkinghorne, pp. 95-96:
If the quantum world requires its own form of logic, one might anticipate that everyday habits of thought may also require some revision when one engages in the task of seeking to understand divine reality. In addition to that general consideration, there are also particular limitations to be expected in the degree of success attainable in the specific case of theology. The infinite nature of God is never going to be exhaustively contained in the finite categories of human thought. The mysterious ineffability of the divine, emphasised by what is called apophatic theology, must always be borne in mind in the course of honest enquiry. Yet the mystery card should be the last one to be played in theological discussion, for Christians believe that God has acted to make the divine nature known in humanly accessible ways, particularly in the life, death and resurrection of Jesus Christ.
