There are few relationships in the world of mainstream religion that are more private, and often mysterious, than the bonds between a priest and a penitent who comes to Confession.

This is especially true when the priest hears the same person’s Confessions over and over for years — even taking on the role of people a believer’s “spiritual father” and guide in life.

So what happens when a priest becomes a bishop? Bishops, cardinals and even popes need to go to Confession and some may even retain ties with their “spiritual fathers” as they climb the ecclesiastical ladder.

Why do I bring this up?

I do so because of a fine detail way down in an Associated Press report that — for a moment, forget teens in MAGA hats and Twitter storms by journalists — may turn out to be a crucial turning point in the complicated story of Pope Francis and wayward bishops involved, in various ways, with sexual abuse.

We will get to the Confessional in a moment. Here is the long, but crucial AP overture:

The Vatican received information in 2015 and 2017 that an Argentine bishop close to Pope Francis had taken naked selfies, exhibited "obscene" behavior and had been accused of misconduct with seminarians, his former vicar general told The Associated Press, undermining Vatican claims that allegations of sexual abuse were only made a few months ago.

Francis accepted Bishop Gustavo Zanchetta's resignation in August 2017, after priests in the remote northern Argentine diocese of Oran complained about his authoritarian rule and a former vicar, seminary rector and another prelate provided reports to the Vatican alleging abuses of power, inappropriate behavior and sexual harassment of adult seminarians, said the former vicar, the Rev. Juan Jose Manzano.

The scandal over Zanchetta, 54, is the latest to implicate Francis as he and the Catholic hierarchy as a whole face an unprecedented crisis of confidence over their mishandling of cases of clergy sexual abuse of minors and misconduct with adults. Francis has summoned church leaders to a summit next month to chart the course forward for the universal church, but his own actions in individual cases are increasingly in the spotlight.

The pope's decision to allow Zanchetta to resign quietly, and then promote him to a new No. 2 position in one of the Vatican's most sensitive offices, has raised questions again about whether Francis turned a blind eye to the misconduct of his allies or dismissed allegations against them as ideological attacks.

Yes, “naked selfies” in a Vatican story. Were these photos sent to others or kept for — oh well, whatever, never mind.
