CINCINNATI—Priests should not kiss, tickle or wrestle children, the Roman Catholic Archdiocese of Cincinnati says in its most detailed list yet of behaviors deemed inappropriate for staff members.

The newest version of the Decree on Child Protection also prohibits bear hugs, lap-sitting and piggy-back rides, among other interactions between its clergy and children. Handshakes, high-fives, shoulder-to-shoulder hugs and pats on the back are still acceptable.
