Roman Catholic Diocese of Montalcino

[4] In 1528, Pope Clement VII separated the two dioceses of Montalcino and Pienza into two episcopal jurisdictions with two bishops.

[5] On 15 June 1772, Montalcino gained territory from the Diocese of Chiusi and from the Diocese of Pienza[6][2] The cathedral was originally a collegiate church, dedicated to the Holy Saviour (San Salvatore) The cathedral was staffed and administered by a Chapter, composed of four dignities (the Archdeacon, the Archpriest, the Provost, and the Primicerius) and nine Canons.

There were in addition four honorary Canons [7] The Second Vatican Council, in order to ensure that all Catholics received proper spiritual attention, decreed the reorganization of the diocesan structure of Italy and the consolidation of small and struggling dioceses.

Based on the revisions, a set of Normae was issued on 15 November 1984, which was accompanied in the next year, on 3 June 1985, 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.
