Catholic inheritance
Rome’s visible religious identity is Roman Catholic.
Rome’s early Christian history predates later Catholic–Protestant divisions, but the city’s modern public religious landscape is overwhelmingly Roman Catholic: parishes, basilicas, shrines, institutions, feasts, and the presence of the Vatican. That inheritance deserves accurate description. It does not, by itself, tell us what an individual believes or whether that person practices the Catholic faith.
