[2] Tradition claims that St. Paul the Apostle established the diocese of Malta in the year 60 A.D when he ordained the Roman governor, Saint Publius, as the first bishop of Malta and saint.

The Diocese of Malta was made a suffragan diocese to the Metropolitan Archdiocese of Palermo[3] by a Papal Bull of Pope Adrian IV on 10 July 1156 and confirmed by Pope Alexander III on 26 April 1160.

The Catholic Caritas Malta, one of the best-known civil-society organisations in the country, was founded in 1968 at the initiative of Archbishop Mikiel Gonzi and Bishop Nikol Cauchi.

[4] There are two cathedrals in the diocese: The Metropolitan Cathedral of Saint Paul, in Mdina, and the Co-Cathedral of Saint John the Baptist, located in Valletta.
