Beautifully put, JP.
Just to explain why I call them Cathedral Moments - I realized one day that I felt like I was in church when I was out in nature. That was the day I realized I was a Pantheist. To me, nature is my church, thus, when I am blessed with the opportunity to see something truly special, I think of the grandest church, a cathedral.
One moment I will never forget was a walk I took during lunch. I walked around Jacob's Pond over in the town I grew up in. There was a large, moss-covered log blocking my path. As I looked to go around it, I realized there were rays of sun shining down on the little clearing I was in - one was highlighting the top of the log. Hovering over that log, highlighted in the sun, was the most beautiful iridescent bee-like creature, just hanging there, in the perfect light....I have no idea what the 'bee' was, but it was truly a beautiful moment, something even the best camera couldn't catch.
