John Nienstedt, the archbishop of Saint Paul & Minneapolis, has denied allegations that he's gay or has engaged in sexual acts with other men.

“I'm not gay,” Nienstedt told the Star Tribune. “And I'm not anti-gay.”

The archdiocese hired an outside law firm to investigate “multiple allegations” against Nienstedt of inappropriate sexual conduct with seminarians, priests and other men. Church officials said the investigation is ongoing.

Nienstedt played a key role in Minnesota's marriage equality debate, spearheading an effort for a constitutional amendment to ban such unions in 2012.

He told the paper that he was arguing that marriage should be a heterosexual union: “It wasn't to put down people with same-sex attractions.”

His rhetoric, however, included calling marriage equality the Devil's handiwork.

“Today many evil forces have set their sights on the dissolution of marriage and the debasing of family life,” Nienstedt wrote in an op-ed published in Legatus Magazine. “Sodomy, abortion, contraception, pornography, the redefinition of marriage, and the denial of objective truth are just some of the forces threatening the stability of our civilization. The source of these machinations is none other than the Father of Lies. Satan knows all too well the value that the family contributes to the fabric of a good solid society, as well as the future of God’s work on earth.”
