Most Protestant churches do not have a “church policy” regarding child protection.
That’s unfortunate, because it can have serious consequences. If an incidence of child molesting hits your church, be sure that a lawsuit is likely to hit the church. That "hit" could be a crippling financial blow that might destroy it. It does not have to be that way, if the church would take certain steps to protect itself legally. Those steps necessarily involve the protection of the children in the care and custody of the church.
