Diocese of Concordia-Pordenone
diocese of the Catholic Church in Italy
The Diocese of Concordia-Pordenone (Latin: Dioecesis Concordiensis-Portus Naonis) is a Latin diocese of the Catholic Church situated in northeastern Italy, at the northern end of the Adriatic Sea, between Venice and Udine. Since 1818, Concordia Veneta, has been a suffragan of the Archdiocese of Venice. Bishop Andrea Casasola attended the Provincial Council of the Provincia Veneta in October 1859 as a suffragan of the Patriarch of Venice, Cardinal Giuseppe Luigi Trevisanato. The name of the diocese was changed to its present form in 1971.
History
Concordia is an ancient Venetian city, called by the Romans Colonia Julia, and is situated on the Lemene River, between the Rivers Tagliamento and Livenza, two miles south of Portogruaro, not far from the Adriatic. Today there remain of the city only ruins and the ancient cathedral. The eighty-nine martyrs of Concordia, who were put to death under Diocletian, are held in veneration; their cult is recent, however, and based on late and dubious material.
The monk, author, and controversialist, Tyrannius Rufinus (345–411), was born in Concordia, but was baptized in Aquileia, where he became a monk.
During the fifth century the city was destroyed by Attila.
The first known bishop of Concordia is Clarissimus, who, at a provincial synod of Aquileia in 579, helped to prolong the Schism of the Three Chapters; this council was attended by Augustinus, later Bishop of Concordia, who in 590 signed the petition presented by the schismatics to Emperor Mauricius.
