Janiak's resignation follows accusations made in a documentary about his handling of two abuse cases.

The documentary "Playing Hide and Seek" was posted online in May this year. The film exposed two cases of pedophile priests that Janiak failed to take action against.

The film featured court testimony about Janiak's role in helping transfer one priest from Wroclaw to another diocese; something which happened even after a criminal investigation had begun.

The priest was subsequently convicted and defrocked.

The film also documented an alleged sex abuse cover-up relating to another priest during Janiak's time as Kalisz bishop, a position he held since 2012.

In June this year, Pope Francis ordered Janiak to leave Kalisz. He forbade the bishop from having any influence on how the diocese is run pending the investigation.

The film was the second focused on Polish clergy abuse to be made by brothers Tomasz and Marek Sekielski.

Their first film last year, "Tell No One," addressed clerical abuse in Poland. The film has been viewed almost 24 million times on YouTube.

The Polish bishops conference reported the news on its website on Saturday. It posted a statement from the Vatican ambassador to Poland simply saying that Janiak had resigned.

The statement noted the archbishop of Lodz, Grzegorz Rys would be the "apostolic administrator" of Kalisz until the position is permanently filled.

A spokesman for the Polish Bishops' Conference said: "It is understandable that such information arouses numerous social reactions and evokes emotions among the faithful. Currently, we are waiting for a reliable explanation of the media reports on this event, which — once again — should never take place, especially among the people of the Church."

However, in putting forth his beliefs about the psychology of paedophile priests, he has ventured outside his area of expertise ("'Give me the boy at seven' ... look where that led us", March 2-3.)

As a clinical psychologist who has spent over 33 years treating adult survivors of childhood sex crimes, I am no expert on the law.

I have also never treated paedophile priests.

However, I am an expert on what the victims of paedophile priests experienced as children.

Paedophile priests are not, as Robertson suggests, merely hapless emotionally weak, immature victims of celibacy.

Working with survivors of clerical sexual abuse, it has become clear that the pattern of these crimes is consistent with highly organised serial predation, not one-off moments of weakness.

My patients have been the victims of serial predators whose modus operandi fits the profile of the worst kind of sociopath.

Let's not confuse a pathological and criminal absence of conscience and moral compass with "immaturity" and "weakness".

Priests do not become paedophiles due to immaturity, weakness and sexual frustration. Paedophiles become priests because it gives them easy access to trusting children, families and communities where they will be respected and obeyed without question.

The sad fact is that the priesthood is the perfect job and the perfect cover for a paedophile with no scruples.

The natural solution to sexual frustration is not paedophilia.

Celibacy does not cause men to become attracted to children.

According to my patients, paedophile priests display and utilise the full suite of sociopathic behaviours to plan, execute and cover up their crimes.

This includes threat, blackmail, intimidation and manipulation of children and their families.

They are experts in using their extraordinary power and influence to systematically and efficiently exploit a child's innocence, obedience, love of God, fear of the devil and their instinct to protect their loved ones. Continue reading
