Christus Dominus (Christ the Lord; abbreviation "CD") is the Second Vatican Council's "Decree on the Pastoral Office of Bishops".
The document was approved by a majority vote of 2,319 to 2[1] of the assembled bishops and was promulgated by Pope Paul VI on 28 October 1965.
[2] Christus Dominus calls for strong episcopal conferences of bishops, to set the standard for the church in their region, while fully supporting the Vatican and the Pope.
Therefore, this sacred synod considers it to be supremely fitting that everywhere bishops belonging to the same nation or region form an association which would meet at fixed times.
Thus, when the insights of prudence and experience have been shared and views exchanged, there will emerge a holy union of energies in the service of the common good of the churches.
