This depends on several factors. First, what are the other alternatives? Second, can the parents home educate their children, which we believe to be God's way? Third, if home education is not an option for some reason, is the Catholic school a better learning envronment than the local public schools? Fourth, are there any other Christian schools or private schools that could be considered.
As we have said, we believe that God's plan is for parents to educate their children. But in the event that this is not possible, there could be situations where the Catholic school is the best option. The parents, however, must be diligent at helping their children sort through whatever false doctrine they may be taught.
