The Journey Continues
When I did my first baptism as a priest, we had a minor crisis. As I poured water on the baby girl’s head, she began to cry. That’s when I realized that the water was cold. She did not stop crying until we were able to get a blanket over her head again and warm her up. At my second baptism, I tried to avoid the same mistake, and, because we were renting a community hall at the time, I heated up some water on the stove in the kitchen, and hoped that it wouldn’t cool off too much before the service. Just before the baptism, I checked the water, and it was a beautifully nice temperature. When I began pouring the water over the baby girl’s head, guess what? She began to cry. I decided that there were probably two explanations for this: 1) baby girls don’t like me, or 2) baby girls don’t like having water poured on their heads when they are comfortably resting in their mothers arms, half asleep. I prefer the second explanation.

The Way Home
So, to me, for someone to say that they are “spiritual, but not religious,” means that they are saying something to the effect of “I’m a human being.”
Of course, I’m being deliberately obtuse with my own question, because what people generally want to convey with that statement is that they simply do not subscribe to any form of organized religion, and prefer to find their own method of making sense of the world; that they do not find any meaning in the structures others have created, but prefer to create their own order within the chaos.
