Vatican City different from Holy See
Governance
The politics of Vatican City takes place in the context of an absolute elective monarchy, in which the head of the Catholic Church holds power. The Pope exercises principal legislative, executive, and judicial power over the State of Vatican City (an entity distinct from the Holy See), which is a rare case of a non-hereditary monarchy.Languages
Vatican City has no formally enacted official language, but, unlike the Holy See which most often uses Latin for the authoritative version of its official documents, Vatican City uses only Italian in its legislation and official communications. Italian is also the everyday language used by most of those who work in the state. In the Swiss Guard, Swiss German is the language used for giving commands, but the individual guards take their oath of loyalty in their own languages: German, French, Italian or Romansh. The official websites of the Holy See and of Vatican City are primarily in Italian, with versions of their pages in a large number of languages to varying extents.
