The vocation of deacon was gradually transformed in the first centuries of Christian history from an office exercised permanently by men and, more rarely, women into a temporary office reserved to those who were candidates for ordination as priests and therefore reserved to men. Deacons were then ordained as "transitional deacons" with the understanding that they would eventually receive priestly ordination. Participants in the
Second Vatican Council recommended the restoration of the ancient permanent diaconate with votes taken in October 1963 and September 1964. The Council's
Dogmatic Constitution on the Church (
Lumen gentium) said that with papal approval territorial groups of bishops could "restore" the diaconate "as a proper and permanent rank of the hierarchy". The role could be "conferred upon men of more mature age" even if married and upon young men bound by "the law of celibacy".
Pope Paul VI adhered to the Council's understanding when he authorized the establishment of a ministry of permanent deacons in 1967, restricted to men and allowing for married men. Relating these permanent deacons to the pre-existing status of transitional deacons, he provided for both permanent and transitional deacons to belong to a single order in the hierarchy of Church offices and both were to be ordained according to the same rite. A 2002 report by the
International Theological Commission, an advisory body to the
Congregation for the Doctrine of the Faith, examined the question of women deacons. The result of a five-year effort, it was called "From the Diakonia of Christ to the Diakonia of the Apostles". Cardinal
Joseph Ratzinger, later Pope Benedict XVI, chaired the all-male ITC committee that produced the report. Its conclusions did not absolutely exclude the possibility of women deacons but took a more nuanced stance. The ITC’s general secretary, Father Georges Cottier, later a cardinal, said the study's consideration of women deacons did “tend to support the exclusion of this possibility". On 26 October 2009,
Pope Benedict XVI modified
canon law to clarify the distinction between deacons and priests, writing that only priests act "in the person of Christ", that the diaconate and priesthood are specific ministries rather than stages within the sacrament of order. Archbishop
Paul-André Durocher of
Gatineau, Canada, raised the idea of ordaining women as deacons when speaking to the
Synod on the Family in 2015, and continued to raise the issue following the synod. A few senior prelates took opposing positions on the possibility of a female diaconate, including Cardinals
Walter Kasper and
Gerhard Müller. Some bishops support the ordination of women as deacons. In a May 2016 audience with women religious at the triennial assembly of the
International Union of Superiors General (UISG), Pope Francis was asked about whether women could be included in the permanent diaconate, and was asked about the possibility of establishing an official commission to study the matter. Francis responded that the history was "obscure" and that it was not clear what role
deaconesses played or whether they were ordained, and added: "It seems useful to me to have a commission that would clarify this well." Vatican spokesman
Federico Lombardi subsequently said that Francis "did not say he intends to introduce a diaconal ordination for women and even less did he speak of the priestly ordination of women." ==First Commission==
