The Archdiocese of Saint Paul & Minneapolis has confirmed that it is conducting an independent investigation into allegations against Archbishop John Nienstedt of inappropriate sexual conduct with seminarians, priests and other men.

According to Commonweal Magazine, the archdiocese has hired an outside law firm to investigate “multiple allegations.”

Jennifer Haselberger, the archbishop's former top canon lawyer, quit in protest last year.

“I believe that the investigators have received about ten sworn statements alleging sexual impropriety on the part of the archbishop dating from his time as a priest in the Archdiocese of Detroit, as Bishop of New Ulm, and while coadjutor and archbishop of St. Paul and Minneapolis,” Haselberger told Commonweal.

“He also stands accused of retaliating against those who refused his advances or otherwise questioned his conduct,” she added.

Nienstedt denied the charges in a blog post.

“These allegations are absolutely and entirely false,” he said. “The allegations do not involve minors or lay members of the faithful, and they do not implicate any kind of illegal or criminal behavior. The allegations involve events alleged to have occurred at least a decade ago, before I began serving in the Archdiocese of St. Paul and Minneapolis.”

Nienstedt played a key role in Minnesota's marriage equality debate, calling such unions 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.”
