Furthermore, the Catholic partner in a mixed marriage is obliged, not only to remain steadfast in the faith, but also, as far as possible, to see to it that the children be baptized and brought up in that same faith and receive all those aids to eternal salvation which the Catholic Church provides for her sons and daughters.
The problem of the children's education is a particularly difficult one, in view of the fact that both husband and wife are bound by that responsibility and may by no means ignore it or any of the obligations connected with it. However the Church endeavors to meet this problem, just as she does the others, by her legislation and pastoral care.
Accordingly, in order that ecclesiastical discipline on mixed marriages be more perfectly formulated and that, without violating divine law, canon law should have regard for the different circumstances of married couples, in accordance with the mind of the Second Vatican Council expressed especially in the decree Unitatis Redintegratio [AAS 57 (1965), pp. 90-112.] and in the declaration Dignitatis Humanae, [AAS 58 (1966), pp. 929-946.] and also in the Synod of Bishops, we, by our own authority, and after mature deliberation, establish and decree the followings norms:
1. A marriage between two baptized persons, of whom one is a Catholic, while the other is a non-Catholic, may not licitly be contracted without the previous dispensation of the local Ordinary, since such a marriage is by its nature an obstacle to the full spiritual communion of the married parties.
2. A marriage between two persons of whom one has been baptized in the Catholic Church or received into it, while the other is unbaptized, entered into without previous dispensation by the local Ordinary, is invalid.
3. The Church, taking into account the nature and circumstances of times, places and persons, is prepared to dispense from both impediments, provided there is a just cause.
4. To obtain from the local Ordinary dispensation from an impediment, the Catholic party shall declare that he is ready to remove dangers of falling from the faith. He is also gravely bound to make a sincere promise to do all in his power to have all the children baptized and brought up in the Catholic Church.
5. At an opportune time the non-Catholic party must be informed of these promises which the Catholic party has to make, so that it is clear that he is cognizant of the promise and obligation on the part of the Catholic.
6. Both parties are to be clearly instructed on the ends and essential properties of marriage, not to be excluded by either party.
