What is the “context” you refer to?
If you are with humans, you will run a risk of sexual abuse. I wish I could say that you are safe if you are with so and so. But I can’t. Because any organization of humans, not matter how loose or strict, carries a percentage of predators. Because the Church draws her members from human society, there will be, statistically speaking, sexual abuse. This is a fact and it is SEPARATE from the issue of morality, coverups and responses.
The reason this fact is an important piece of context is that it provides information important to understanding where to focus reform and intervention. If sexual abuse rates within society were 1% and the church was, say, 10%, it would indicate the need for further information before reforms were put into place. For instance, in this scenario, is it a problem in teachings from the pulpit or current Catholic culture that encourages the sexualization of children? Is it a known haven for predators that encourages their protection? Is there some other factor that pre-disposes the Church to have an unusually high number of sexual predators? Since the incidence of abuse by priests is not significantly different from the general population, then we know that the issue is concupiscence and not Catholic culture or teachings. This, then, leads us in the direction of looking at contemporary culture for advice from the secular culture as to how to respond to the issues and how to put regulations into place to prevent such crimes to the highest potential possible.
Of separate consideration is the issue of how credible accusations were addressed in the past. If you look into abnormal psychology trends of the past 70 years or so, you will find that the idea that pedophiles could be “cured” by a variety of therapies and interventions, including “change of location”, was prevalent. All such misconduct, be it a teacher or a parent or a relative or a social worker or a pediatrician or whatever, were mostly handled in the same manner. If they DIDN"T handle it in this way, they were open to lawsuits from priests who were “unfairly and harshly treated/unemployed”. If they DID follow the opinion of the experts, they would be less liable, as it were. These circumstances of context provide an explanation for the actions of the Church and that is also why they are important.
But, do they provide an excuse? I personally don’t think so. I think the teachings of Christ about misconduct within the Church, the pervasiveness and persistence of concupiscence and the reality of evil should have been enough to guide their actions in a different direction. Additionally, in public settings, measure of how to prevent and respond to sexual misconduct have been in place for years now. The Church should have voluntarily made available this information at that time when we began to realize that changes of scenery and a sincere talking to weren’t preventing or curing anything. But they didn’t. For that, I believe they are culpable.
