There was also a predecessor in the form of a Diocese of Lipari, which appears to have become extinct, perhaps due to Saracen raids in the 9th century.[6] The bishops known by name are:
The importance of Patti grew, however, when Duke Robert Guiscard and Count Roger I founded on the island of Lipari Patti a Benedictine abbey, dedicated to Saint Bartholomew, in c. 1085;[8] the abbey was joined to the Abbey of S. Salvatore when it was founded in 1094.[9] On 14 September 1131 Anacletus II, the pope from the double election of 1130 who was recognized in the Kingdom of Sicily, made the monastery of S. Bartholomew in Patti an episcopal see, and at the same time made the Abbey of Lipari an episcopal seat, uniting them in the person of one bishop, who would be consecrated by the Archbishop of Messana.[10] The new See was endowed by King Roger II of Sicily, making it richer than the long established See of Syracuse.[11]Pope Eugenius III in 1157 confirmed the action of Anacletus II.
Frederick III of Sicily (1295–1337) devastated Patti because the town was a supporter of his Angevin rivals, Robert and Philip of Naples.[12] The French Pope John XXII, who supported the Angevins, laid all of Sicily under an interdict, which lasted from 1321 to 1335, causing severe problems between the Sicilian episcopate and the monarchy.
On 18 April 1399, Lipari and Patti were separated,[13] and the first bishop of the separate see of Patti was Francesco Hermemir. His predecessor, Francesco Gaptulus, continued as Bishop of Lipari.
The Cathedral of S. Bartolommeo in Patti had a chapter consisting of five dignities and nine canons.[14]
In 1827 the bishopric gained territory from the Metropolitan Archdiocese of Messina. On 20 May 1844 the diocese exchanged territory with the bishopric of Cefalù.
The diocese had in the early 20th century 49 parishes, 20,000 inhabitants, 5 religious houses of men, and 15 of sisters, conducting 4 institutes for girls and several schools.

^Paulinus was Bishop of Tauriana in the Abruzzi, and was ordered by Pope Gregory I to administer the diocese of Lipari and live there. In 597 Pope Gregory instructed the Bishop of Reggio and the Bishop of Lipari to come to Rome. Whether this was Paulinus, or a successor in the diocese of Lipari, is unknown.
