Fisherman - "And US High Courts will vindicate it."
I don't think so. That is wishful thinking. Clergy-penitent privilege already does not apply in several states when it concerns child abuse.

This privilege, however, is not absolute. While clergypenitent privilege is frequently recognized within the reporting laws, it is typically interpreted narrowly in the context of child abuse or neglect. The circumstances under which it is allowed vary from State to State, and in some States it is denied altogether. For example, among the States that list clergy as mandated reporters, Guam, New Hampshire, and West Virginia deny the clergy-penitent privilege in cases of child abuse or neglect. Four of the States that enumerate “any person” as a mandated reporter (North Carolina, Oklahoma, Rhode Island, and Texas) also deny clergy-penitent privilege in child abuse cases.
