Until recently, the Richland, Washington, shop was better known for its artistic arrangements than its stance on same-sex marriage.

But in March, Barronelle Stutzman, the shop’s 68-year-old proprietress, refused to provide wedding flowers for a longtime customer who was marrying his partner. Washington state legalized same-sex marriage in December.

An ardent evangelical, Stutzman said she agonized over the decision but couldn’t support a wedding that her faith forbids.

“I was not discriminating at all,” she said. “I never told him he couldn’t get married. I gave him recommendations for other flower shops.”

Washington state Attorney General Bob Ferguson disagreed, and filed a consumer protection lawsuit against Arlene’s Flowers. The ACLU also sued on behalf of the customer, Robert Ingersoll, who has said Stutzman’s refusal “really hurt, because it was someone I knew.”

Among conservative Christians, Stutzman has become a byword - part cautionary tale and part cause celebre.
