It is the moral responsibility of every adult to report the sexual abuse of children directly to the authorities so that a proper investigation can begin by the police or CPS. This reporting should be direct. It improves the investigation when the reporting is unfiltered. In many states it is a legal requirement that anyone who suspects abuse should report it. It is up to these authorities to investigate and in-house investigations often muddy the waters and sometimes even allow the molestation to continue.
ITA. I also understand what southsleuth was saying. IMO, the definition of a cult is subjective, and any institution with a legal process that operates apart from society's could validly be viewed as a cult.
I say this from experience. I once belonged to a church that I discovered had long been hiding abuses by the ministry and elders. Some former members were exposing these abuses, and several ministers and elders who had molested children were finally reported to authorities and brought to justice. But, historically, the abuses were silenced or, when brought to the attention of higher-ups, the offenders were simply sent to other states where they continued their abuse with new victims.
While most members of that church, including ministers, are good people with good intentions, the structure of that church is conducive to such abuses. Some people, though, prefer to throw doubt on abuse allegations rather than have their idealistic view of their church, or a minister or elder, tarnished.
IOW, any institution with an organizational structure that includes its own "judicial" system can unwittingly allow criminals to flourish within the organization.
