Francis gives the local diocsean Novus Ordo bishops the ability to grant faculties to the priests of the FSSPX to officiate at weddings under certain conditions.
As you are aware, for some time various meetings and other initiatives have been ongoing in order to bring the Society of St. Pius X into full communion. Recently, the Holy Father decided, for example, to grant all priests of said Society the faculty to validly administer the Sacrament of Penance to the faithful (Letter Misericordia et misera, n.12), such as to ensure the validity and liceity of the Sacrament and allay any concerns on the part of the faithful.
Following the same pastoral outlook which seeks to reassure the conscience of the faithful, despite the objective persistence of the canonical irregularity in which for the time being the Society of St. Pius X finds itself, the Holy Father, following a proposal by the Congregation for the Doctrine of the Faith and the Pontifical Commission Ecclesia Dei, has decided to authorize Local Ordinaries the possibility to grant faculties for the celebration of marriages of faithful who follow the pastoral activity of the Society, according to the following provisions.
Insofar as possible, the Local Ordinary is to grant the delegation to assist at the marriage to a priest of the Diocese (or in any event, to a fully regular priest), such that the priest may receive the consent of the parties during the marriage rite, followed, in keeping with the liturgy of the Vetus ordo, by the celebration of Mass, which may be celebrated by a priest of the Society.
Where the above is not possible, or if there are no priests in the Diocese able to receive the consent of the parties, the Ordinary may grant the necessary faculties to the priest of the Society who is also to celebrate the Holy Mass, reminding him of the duty to forward the relevant documents to the Diocesan Curia as soon as possible.
Certain that in this way any uneasiness of conscience on the part of the faithful who adhere to the Society of St. Pius X as well as any uncertainty regarding the validity of the sacrament of marriage may be alleviated, and at the same time that the process towards full institutional regularization may be facilitated, this Dicastery relies on Your cooperation.
The Sovereign Pontiff Francis, at the Audience granted to the undersigned Cardinal President of the Pontifical Commission Ecclesia Dei on 24 March 2017, confirmed his approval of the present letter and ordered its publication.
Rome, from the Offices of the Congregation for the Doctrine of the Faith, 27 March 2017.
