A 17-year-old Roman Catholic teen in Minnesota has been denied confirmation over his support for gay marriage.

Lennon Cihak was denied the religious rite after the Rev. Gary LaMoine at the Assumption Church in Barnesville, Minnesota found a pro-marriage equality post on Cihak's Facebook page.

Lennon posted a photo of himself holding a defaced Minnesota for Marriage sign supporting passage of a failed constitutional amendment limiting marriage to heterosexual couples. The word “NO” was written over “YES,” and the phrase “Marriage One Man, One Woman” was replaced with “Equal Marriage Rights One [blank], One [blank].”

According to the AP, Lennon was denied confirmation in mid-October.

“You kind of know the Catholic beliefs, but I never thought they would deny somebody confirmation because you weren't 100 percent,” said Lennon's mother, Shana Cihak. “I guess that's what shocks me.”

Mrs. Cihak said her son had prepared for his confirmation this year by going to church every week and volunteering around the community.

Lennon said others in his confirmation class had “liked” the photo without facing retribution.

“I just thought it was wrong to single him out,” Mrs. Cihak said.

Mr. Cihak said the family has been told it can no longer participate in Communion at the church.

Lennon supported his faith, saying it was LaMoine who was being too strict.

“He won't loosen up about things,” he said.
