It was the feast of St. Mary, Mother of the Church, so writer Leah Libresco and some friends decided to have a traditional procession through their neighborhood, while praying the Rosary out loud.

"I live in New York City, where this was still not the weirdest thing that anyone would see that day," said Libresco, speaking earlier this winter at the Catholic Information Center in Washington, D.C.

The procession received some puzzled looks along Broadway, near Lincoln Center. Their images of St. Mary sure didn't match the vision of womanhood seen in advertisements they passed.

This wasn't a public statement. All these New Yorkers were doing was celebrating the feast together, creating a face-to-face community with faith, food and fellowship. There's more to life than sitting at home, firing tweets and text messages at the world.

Long ago, Libresco explained, ascetic monks called "stylites" believed they should spend their lives fasting and praying while living atop pillars. This kind of solitude, obviously, was not for the average believer.

Today, many Americans have become "accidental stylites," she said. They are isolated from one another by jammed schedules, job demands and all those digital devices that were supposed to aid communication.

"A lot of folks wind up living hermetic lives, living their faith alone -- nakedly before God -- without the assistance of a monastic superior, or a community or anything else," she said. While monks carefully choose lives of solitude, that path would be "a terrible idea for the rest of us."

Once known as a popular atheist blogger, Libresco began exploring spiritual disciplines after converting to Catholicism in 2012. Her new book is called "Building the Benedict Option: A Guide to Gathering Two or Three Together in His Name." The title is a reference to journalist Rod Dreher's bestseller "The Benedict Option," which challenged modern believers to build local support networks -- involving education, the arts, even small businesses -- in an increasingly post-Christian America. Dreher (a friend of mine for 20 years) wrote the foreword for Libresco's book.

Building on Dreher's manifesto, Libresco wants to encourage Christian hospitality in settings more intense than young-adult gatherings offering shallow chitchat over wine and cheese.

"My goal, always, in building the Benedict Option, is not to turn away from the world," she wrote. "Feeling the need for the thicker community of the Benedict Option … isn't the same as rejecting the world or fearing it. … A claustrophobic feeling can creep into your spiritual life when you practice it alone."
