Roman Catholic Diocese of Caiazzo

[2][3] According to legend, Christianity was introduced into Caiazzo by Priscus, one of the seventy-two disciples of Jesus, first Bishop of Capua.

[7] The cathedral was consecrated on 23 July 1284, by Cardinal Gerardo Bianchi, Bishop of Sabina and papal Legate in Sicily.

[8] The cathedral was staffed and administered by a corporate body, the Chapter, composed of three dignities (the Archdeacon, and two Primicerii) and twenty Canons (two of whom are designated Theologus and Primicerius, in accordance with the decrees of the Council of Trent).

Pope Pius VII, in the bull "De Utiliori" of 27 June 1818, chose to unite the two dioceses of Calvi and Teano under the leadership of one bishop, aeque principaliter.

On 18 February 1984, the Vatican and the Italian State signed a new and revised concordat, which was accompanied in the next year by enabling legislation.

According to the agreement, the practice of having one bishop govern two separate dioceses at the same time, aeque personaliter, was abolished.
