A few dozen people sit quietly for the hourlong service. Music is played, announcements are made and scholars wax poetic about the importance of compassion and community.

Outsiders could be forgiven for believing this service, with its homilies, its passing of the plate, its uplifting songs, belongs in a church.

If so, it’s a church without one big player: God.

Sunday’s congregation in Cambridge is a meeting of the Humanist Community at Harvard University and the brainchild of Greg Epstein, the school’s Humanist chaplain.

A longtime advocate for community building, Epstein and his group of atheists have begun to build their Cambridge community and solemnize its Sunday meetings to resemble a traditional religious service.

To Epstein, religion is not all bad, and there is no reason to reject its helpful aspects.

“My point to my fellow atheists is, why do we need to paint things with such a broad brush? We can learn from the positive while learning how to get rid of the negative," he said.
