ROME (AP) — The Vatican has essentially slapped a retired U.S. bishop on the wrist for “flagrant” imprudent behavior with teenagers, even though a diocesan review board determined a half-dozen allegations of sexual abuse against him were credible.

The Vatican’s Congregation for the Doctrine of the Faith cleared retired Cheyenne, Wyoming Bishop Joseph Hart of seven accusations abuse, determined that five others couldn’t be proven “with moral certitude” and that two cases involving boys, who were 16 and 17, couldn’t be prosecuted given the Catholic Church didn’t consider them minors at the time of the alleged abuse, the diocese reported Monday. Another allegation wasn’t addressed in the decree.

Hart, 89, had long maintained his innocence and denied all allegations of misconduct.

The Vatican decision clearly disappointed Hart’s successor, Bishop Steven Biegler, who stressed that the Vatican’s findings didn’t mean Hart was innocent, just that the Holy See determined that the high burden of proof hadn’t been met.

Biegler has previously stood by the findings of his review board, and a diocesan statement noted the qualifications of its members: “law enforcement; school administration; a doctor of psychology; a pediatrician; a psychotherapist, who treats sexually abused children; and a judge, who was a criminal prosecutor for 13 years involving crimes against children, primarily child sexual abuse.”

On the other hand, the Vatican’s Congregation for the Doctrine of the Faith, or CDF, relies on the judgment of priests and bishop canon lawyers, and ultimately the pope. The Vatican for decades has been blasted by victims’ groups for giving bishops a pass when they have been accused of sexual abuse themselves or of covering it up.

A few exceptions have been made in recent years, most famously in the case of ex-Cardinal Theodore McCarrick, who was defrocked after the CDF determined he had abused minors as well as adults, including during confession — essentially the same allegations against Hart.

As a result, the sentence showed the arbitrary nature of Vatican’s canonical sex abuse judgments, which aren’t public. Hart’s previous diocese of Kansas City-St. Joseph reached court settlements years ago with at least 10 victims. But Wyoming criminal prosecutors also decided last year not to proceed with charging Hart.

In its decree, the CDF rebuked Hart “for his flagrant lack of prudence as a priest and bishop for being alone with minors in his private residence and on various trips which could have been potential occasions endangering the ‘obligation to observe continence’ and that would ‘give rise to scandal among the faithful,’” the diocese said.

Hart was also rebuked for failing to observe previous Vatican restrictions prohibiting him from having contact with minors and seminarians and from participating in public engagements, the diocese said, adding that those restrictions remain in place.

“Today, I want the survivors to know that I support and believe you” Biegler said in a statement. “I understand that this announcement will not bring closure to the survivors, their family members, Bishop Hart and all those affected.”

Hart was a priest in Kansas City, Missouri, for 21 years before moving to Wyoming, where he served as auxiliary and then full bishop from 1976 until his retirement in 2001. The first known allegations against Hart dated to the early 1960s and were made in the late 1980s. At least six men came forward in the past few years to say Hart abused them in Wyoming.
