Is it still a religion if it doesn't believe in anything?

I'm not surprised any longer, but it still hurts to see things like this.. At Trinity United Methodist Church in Austin, Texas:

For the congregation of the church, at 600 E. 50th St., a witch leading worship isn't scandalous. It isn't even that unusual. Trinity members have hosted American Indian shamans, Buddhist priests and other faith leaders, including Wiccans, before. They even practice their own pagan-inspired rituals at services. "It's not my way or hell," said Trinity member Linda Eldredge. "All are welcome here. Everybody's got something to offer."

Are these church members Christian? That's God's call. Is this church Christian? Not even close. Is it anything? Rev 3:15-16?
