The priests, bishops, and other members of the Church who have sexually assaulted, abused, or harassed those whom they were supposed to protect should be held accountable for their actions. Their victims are many: the people they directly assaulted, their friends and loved ones who might not have known the cause but knew that something was wrong, the priests and other members of the Church who had no part or knowledge of these abuses but who now have to deal with the continual suspicion, and the many people who have turned away from God because of these assaults. Thankfully, the Church is taking steps to address the problem.
This is going to take some time. The total population of Roman Catholics around the world is over 1.2 billion. If that population was a country, it would be the third largest in the world. There are only about half a million priests to serve all of those people. For comparison, the United States has a population of around 325 million (around 70 million of them Catholic) for which it has around 23 million governmental employees to serve them (we can discuss oversized bureaucracies some other time). Any human organization of with that level of population, spread throughout the world, will have problems that it needs to overcome. Hopefully, we will continue to do and make the Church, and the world a better and safer place.
