You asked, “What systems did the diocese have in place to prevent this or encourage people who know of it to go to the authorities?” The mother of the minor reported it to the police and not to any cardinal, bishop, or priest. The diocese immediately acted on it after they found out about the complaint. The rest is in the news article.
To address in general,
Yes, we detest all clerical abuse especially on innocent children.
Yes, we hope that there is a more definitive, an aggressive way to eradicate all these abuses but even in industrial countries like the United States with its laws and enforcement plus ammunition, crimes still prevail to this day.
Yes, we need to prevent pedophiles/criminals from finding opportunities in the habit. There are those who suggest a stricter screening of seminarians. Seminary applicants today undergo screenings like psychological tests and intensely personal interviews. Yes, these screenings may, in a way, prevent, but where there is already a shortage of priests, we tend to embrace those who enter.
Many of these abuses are decades old. Initially, according to Thomas Plante of Stanford University, it appeared to be reasonable to cure erring priests through counseling, and return them to priestly duties. He said that in hindsight, it was a tragic mistake. The Bishops, who were accused of covering up these abuses, must have acted in such leniency to preserve the number of clergy due to the shortage, but oh, the consequences…
Is the Vatican under the Papacy of Francis doing something about this?
Pope Francis created the Pontifical Commission for the Protection of Minors. Some members were themselves victims of abuse.
Pope Francis regularly spoke sternly against these abuses.
Pope Francis humbly acknowledged grave mistakes in the handling of a sexual abuse crisis in Chile, saying he felt shame and inviting victims to Rome to seek their forgiveness personally.
Pope Francis accepted without delay the resignations of cardinals, bishops, and priests who were proven guilty of abuse or were guilty of cover ups.
Will these abuses immediately go away? We must understand that these problems are a result of decades of inaction. Pope Francis is doing the best he can. He inherited a Church mired with many problems…sexual abuse is one of them…
