Secularists don’t usually proselytize, but a group of Calgary non-believers is on a mission to spread doubt about the existence of God.

About a dozen people came to Sunday’s gathering of the Calgary Secular Church.

The church aims "to provide fellowship, community and enlightenment to the [secular, atheist or humanist] community," says its website.

According to Korey Peters, who co-founded the church, issues of mortality and the meaning of life are talked about from a non-religious perspective.

"If you do have faith when you come here, we're not going to kick you out — but your faith will be challenged. It does not get a free ride," he said.

Church-goer Keir Wright said that comes as a relief.

"When I get here I just find a bunch of like-minded people who believe in the same things that I believe in, and the conversation is absolutely stimulating," he said.

Peters said he grew up an evangelical Christian, and later lost his faith. But he still believes in "the power of assembly," he said.

"I want it to be OK for people who don't have faith and don't have religion to have that same community."

The church holds meetings on the last Sunday of the month at 10:30 a.m. at the Green Fools Theatre at 2404 Erlton Road S.W.
