The order was given the name of "Regular Clerics of St. Paul" (Clerici Regulares Sancti Pauli). In 1538 the grand old monastery of Saint Barnabas by the city wall of Milan was given to the congregation as their main seat, and thenceforth they were known the popular name of "Barnabites". After the death of Zaccaria in 1539, the congregation was favored and protected by Archbishop Charles Borromeo of Milan and later by Francis de Sales because of their successful missionary work in Upper Italy. Charles Borromeo presided, in 1579, as Cardinal Protector, over the commission which wrote the Constitutions of the Order. The General Chapters of the Order were regularly held at Milan until the reign of Pope Alexander VII (1655–67), who ordered them to convene in Rome. Pope Innocent XI (1676–89), however, finally decreed that they should be held in Rome and Milan alternately.
