The Diaconate was restored as a permanent order of ministry by the Second Vatican Council as part of a renewed vision.
The Permanent Diaconate office assist the bishop in the care, guidance, and support of deacons. The Dicaonate office helps with the planning, supervision, and the formation of diocesan deacons.
The Diaconate flourished in the western church up to the fifth century. For various reasons, it experienced a slow decline and ended up surviving only as a transition stage for candidates preparing for priestly ordination.
On June 18, 1967, Pope Paul VI implemented the recommendations of the Second Vatican Council and restored the Permanent Diaconate.
