⌠Whereas Instituted has no period (unless you leave formation in the case of a Seminarian or step down in the case of a Layman)âŚ
Can you substantiate the âunlessâ.
Obviously if a seminarian is ordained he becomes an ordained minister stops being a layman and instituted minister.
But otherwise I would see the institution as permanent, short of a tribunal punishment of excommunication or âloss of officeâ. Given what has happened to porters, there could be another Motu Proprio abolishing the instituted ministries.
But leaving formation for the priesthood does not change the fact that someone has been instituted and is an instituted minister.
Some documents emphasising the permanence of the instituted ministries, with my
bold highlights:
Catechism of the Catholic Church, n 903:
âLay people who possess the required qualities can be admitted
permanently to the ministries of lector and acolyte. [Footnote 436: Cf. CIC, can. 230.1].â
Catechism of the Catholic Church, 1671: âCertain blessings have a
lasting importance because they consecrate persons to God, or reserve objects and places for liturgical use. Among those blessings which are intended for persons - not to be confused with sacramental ordination - are the blessing of the abbott or abbess of a monastery, the consecration of virgins and widows, the rite of religious profession and the blessing of certain ministries of the Church (
readers, acolytes, catechists, etc.).â
Ceremonial of Bishops, n. 790: âUnless they have already done so, candidates for ordination are to receive these ministries âŚâ. The permanent nature of institution is clear, since it is not to be performed on someone a second time.
Canon 1050, 3°: âfor those to be promoted to the diaconate, certificates of the reception of baptism, of confirmation and of the ministries mentioned in Canon 1035.â
This indicates that there should be a certificate for the institution of a lector and acolyte, emphasizing its permanence.
Canon 230.1: âLay men whose age and talents meet the requirements prescribed by decree of the Bishopsâ Conference, can be given the** stable ministry **of lector and of acolyte âŚâ.
The Rite of Institution of Readers, n 5: âThen all stand, and the bishop, without his miter, invites the people to pray: Brothers and sisters, let us ask God our Father to bless these servants who have been chosen for the ministry of reader. Let us pray that they may be faithful to the work entrusted to them âŚâ.
