Back in the fall of 1993, I made — believe it or not — my first-ever trip as an adult to New York City. I had covered many important news stories in American and around the world, but had never hit the Big Apple.

I stayed in a guest room at Union Theological Seminary, since I would be attending what turned out to be, for me, a pivotal religion-beat conference at the nearby Columbia University School of Journalism. But that’s another story for another day.

Here is the story for this week’s “Crossroads” podcast (click here to tune that in), which is linked this week’s Twitter explosion in which Union Seminary students confessed their environmental sins to some plants and sought forgiveness.

On that beautiful New York Sunday morning, I decided to head to the Episcopal Cathedral of St. John the Divine. I was, at the time, an evangelical Episcopalian (with high-church sympathies) at I was trying to run into my wife’s favorite author — Madeleine L’Engle (click here for my tribute when she died). She was writer in residence at the cathedral, but later told me that she worshipped at an evangelical parish in the city.

Why did she do that? Well, in part because of services like the “Missa Gaia (Earth Mass)” I attended that Sunday. As I wrote later in a piece called “Liturgical Dances With Wolves”:

In the Kyrie, the saxophonist and his ensemble improvised to the taped cry of a timber wolf. A humpback whale led the Sanctus.

Skeptic Carl Sagan preached, covering turf from the joyful “bisexual embraces'' of earthworms to the greedy sins of capitalists. The earth, he stressed, is one body made of creatures who eat and drink each other, inhabit each other's bodies, and form a sacred “web of interaction and interdependence that embraces the planet.'' … The final procession was spectacular and included an elephant, a camel, a vulture, a swarm of bees in a glass frame, a bowl of blue-green algae and an elegantly decorated banana.

The key moment for me?

Before the bread and wine were brought to the altar, the musicians offered a rhythmic chant that soared into the cathedral vault. … “Praises to Obatala, ruler of the Heavens. Praises to Obatala, ruler of the Heavens. Praises to Yemenja, ruler of the waters of life. Praises to Yemenja, ruler of the waters of life. Praises to Ausar, ruler of Amenta, the realm of the ancestors. Praises to Ra and Ausar, rulers of the light and the resurrected soul.” …

Then the congregation joined in and everyone sang “Let all mortal flesh keep silence.' “
