One of the shorter documents of
Vatican II,
Perfectae Caritatis was titled the
Decree on the Adaptation and Renewal of Religious Life, referring to
Roman Catholic religious orders. Approved by vote of 2,321 to 4 of the bishops assembled at the council, the decree was promulgated by
Pope Paul VI on
October 28,
1965. As is customary for such documents the title is taken from the first words of the decree, "perfect charity" in
Latin.
