Which papal weapon suspended all church service within a kingdom or region?

Answer 1

Roman Catholic AnswerYou are asking about an interdict. An interdict is not a weapon, nor is it strictly papal. It is a censure forbidding the faithful the use of certain sacred privileges, such as Christian burial, some of the sacraments, and attendance at liturgical services. It may be imposed as a vindictive penalty for a fixed period because of some grave act against the common good of the Church. In this case religious services are curtailed, although sacraments may be given to the dying, marriages celebrated, and Holy Communion may be administered IF the interdict is general not personal. A general interdict may be inflicted only by the Holy See, Parishes and persons may be interdicted only by the local Ordinary - usually the Ordinary is the Bishop.
