I think many orders have a psych eval for tell tale signs. Things about their upbringing, their past, etc.
But before the priest scandals, going way back in time:
Saints, and I mean many of them were grave sinners. Some owned slaves. Some abused people. Some killed. Some had children and never married. And the list goes on and on and on…Why? Because we’re all sinners. The saints were sinners.
So, what can we tell about a person who is about to become a priest? Can we tell they will fall, fail, and commit a sin? Even the most atrocious one? And the answer fairly/simply is, no. You can do your best to prevent it. But idoesn’t stop it. Heck, if the litigants and lawsuits arise trying to protect children, then why do they continue to hand condoms to children, while teaching them how to have sex in public education? It’s not to side track the responsibility in the Church for what happened. But the same populace,when it comes to abuse, do not rail against and up the education system. Or any of the wonderful hightlights of the erotic imagery industry, or eve prostitution rings where many children fall into. It does show a motivated bias, though be what was done is terribly wrong and shameful. But nevertheless, the convenient ignorance people have towards all the surrounding circumstances where their children are more vulnerable than with a priest, is abhorrent. I also add, many of the priests who abused children, were doing that during the wonderful free-expression-of-love 60’s/70’s. The sexual revolution, and telling the Church to change her view on sexuality, was a cover for these men who had predatorial infatuations for children. And that was around that time, it catapulted. People who come at the Church are no different than Napoleon who shot fire at a Hospital in Malta, while trying to battle the Turks at the sametime. Church, as many of the Saints and Pope’s have expressed is like a Hospital. But everyone keeps firing on it. People trying to change laws/rules how the Church is governed in her Magisterium. And in addition, how she view morality, especially with regards to sex. And now she is posed to deal with a problem of abuses, wherefore she was supposed to change her view of sexual morality. Pretty glaringly obvious this war hasn’t stopped either.
