12. The Sacred Ecumenical Council confirms and approves the ancient discipline of the sacraments existing in the Oriental Churches, as also the ritual practices connected with their celebration and administration and ardently desires that this should be re-established if circumstances warrant it.

13. The established practice in respect of the minister of Confirmation that has obtained from most early times in the Eastern Church should be fully restored. Therefore, priests validly confer this sacrament, using chrism blessed by a patriarch or a bishop.14

14. All Eastern Rite priests, either in conjunction with Baptism or separately from it, can confer this sacrament validly on all the faithful of any rite including the Latin; licitly, however, only if the regulations both of the common and the particular law are observed.15 Priests, also, of Latin Rite, in accordance with the faculties they enjoy in respect of the administration of this sacrament, validly administer it also to the faithful of Eastern Churches; without prejudice to the rite, observing in regard to licitness the regulations both of the common and of the particular law.¹⁶

15. The faithful are bound to take part on Sundays and feast days in the Divine Liturgy or, according to the regulations or custom of their own rite, in the celebration of the Divine Office.17 That the faithful may be able more easily to fulfill their obligation, it is laid down that the period of time within which the precept should be observed extends from the Vespers of the vigil to the end of the Sunday or the feast day.¹⁸ The faithful are earnestly exhorted to receive Holy Communion on these days, and indeed more frequently-yes, even daily.¹⁹

16. Owing to the fact that the faithful of the different individual churches dwell intermingled with each other in the same area or Eastern territory, the faculties for hearing confessions duly and without restriction given to priests of any rite by their own hierarchs extend to the whole territory of him who grants them and also to the places and faithful of any other rite in the same territory, unless the hierarch of the place has expressly excluded this for places of his rite.20

17. In order that the ancient established practice of the Sacrament of Orders in the Eastern Churches may flourish again, this Sacred Council ardently desires that the office of the permanent diaconate should, where it has fallen into disuse, be restored.21 The legislative authorities of each individual church should decide about the subdiaconate and the minor orders and the rights and obligations that attach to them.²²

18. To obviate invalid marriages when Eastern Catholics marry baptized Eastern non-Catholics and in order to promote fidelity in and the sanctity of marriage, as well as peace within the family, the Sacred Council determines that the canonical "form" for the celebration of these marriages is of obligation only for liceity; for their validity the presence of a sacred minister is sufficient, provided that other prescriptions of law are observed.23
