To answer your concern, just compare this lawsuit to any successful lawsuit filed in the United States.
There are more “Christians” in prison than those unaffiliated with a religious organization.

On average, the chaplains surveyed say that Christians as a whole make up about two-thirds of the inmate population in the facilities where they work.
A church has never been held responsible for the actions of any given member that held no leadership position or special assignment (that indicated some trustworthiness on his or her part) with a very few exceptions.
The only time an organization has ever been held accountable for the actions of a miscellaneous member that held no leadership position, is if they allowed a person with a history of abuse to volunteer in activities sponsored for children or if there was a lack of supervision in such activities.

Within the Jehovah's Witnesses faith, there is no "Sunday School," "church camp," or other children's activities in which children are separated from their parents. The parents of children in the congregation are expected to guide, direct and attend to the needs of their children. The elders are there to give spiritual guidance and direction and any other practical assistance possible, but the parents are there to monitor and discipline their children. Jehovah 's Witness children are not separated from their parents for any spiritual programs or activities.

This is an action by which the plaintiff, an 11-year-old girl, sued the defendant, Renee Der-Ohanian, also known as Renee K. Arakelian, doing business as Happy Valley Ranch, operator of a camp for children, for injuries and damages sustained by her through sexual abuse by an unknown person when she was a visitor at the camp.
The two little girls were assigned to a room in one of the barracks-like buildings, and no adult or supervisor was placed in the room with them. In fact, there was a decided shortage of proper supervision, and this forms the essential ground for the claim that respondent was negligent. The action is premised upon the lack of proper care for the plaintiff.
Outside of this premise, no organization has ever been held responsible for child abuse. This is why the case is being appealed.

Discussion of Liability Issues
Settlement Issues
If Plaintiff was abused, it was committed by Kendrick, a third party not under the control or supervision of the Church Defendants. Kendrick denies abusing Plaintiff. Further, even if, arguendo the jury should find that Kendrick abused Plaintiff in the Kingdom Hall by hugging her and having her sit on his lap while her parents were present, the damages for that alleged conduct would be minimal at best. Also, if the jury finds the Church Defendants liable for abuse of Plaintiff off of Kingdom Hall property (such as in Kendrick's private home), the Church Defendants will have little option except to appeal such a verdict. The Church Defendants could not let such a potential precedent go unchallenged. Finally, Plaintiffs description of the location, nature, and extent of her alleged abuse is contradicted by, among other things, her parents and the elders and thus lacks credibility. No demand for a settlement has yet been made by Plaintiff; however, the Church Defendants will participate in the mandatory settlement conference in good faith.
In the civil courts, a person/organization doesn't even have to violate an established statute to stand trial or a statute like "a legal duty of care" can mean anything a judge and jury wants it to during a proceeding. This is the only reason a case like this was accepted into the legal system in the first place.
This appellant court may uphold the jury verdict because the lower court carries some momentum, but I don't see how the highest court can uphold the jury verdict without expanding liability issues to an unprecedented decree.
