Christus Dominus is the Second Vatican Council's Decree on the Pastoral Office of Bishops. It was approved by a vote of 2,319 to 2 of the assembled bishops and was promulgated by Pope Paul VI on October 28, 1965. The title in Latin means "Christ the Lord," and is from the first line of the decree, as is customary for Roman Catholic documents. (The full text in English is available from the Holy See's website.)
