From Pope St. John Paul II’s Apostolic Exhortation Familiaris Consortio (1981):
The growing number of mixed marriages between Catholics and other baptized persons also calls for special pastoral attention in the light of the directives and norms contained in the most recent documents of the Holy See and in those drawn up by the Episcopal Conferences, in order to permit their practical application to the various situations.
Couples living in a mixed marriage have special needs, which can be put under three main headings.
In the first place, attention must be paid to the obligations that faith imposes on the Catholic party with regard to the free exercise of the faith and the consequent obligation to ensure, as far as is possible, the Baptism and upbringing of the children in the Catholic faith.178
There must be borne in mind the particular difficulties inherent in the relationships between husband and wife with regard to respect for religious freedom: this freedom could be violated either by undue pressure to make the partner change his or her beliefs, or by placing obstacles in the way of the free manifestation of these beliefs by religious practice.
With regard to the liturgical and canonical form of marriage, Ordinaries can make wide use of their faculties to meet various necessities.
In dealing with these special needs, the following points should be kept in mind:
- In the appropriate preparation for this type of marriage, every reasonable effort must be made to ensure a proper understanding of Catholic teaching on the qualities and obligations of marriage, and also to ensure that the pressures and obstacles mentioned above will not occur.
- It is of the greatest importance that, through the support of the community, the Catholic party should be strengthened in faith and positively helped to mature in understanding and practicing that faith, so as to become a credible witness within the family through his or her own life and through the quality of love shown to the other spouse and the children.
Marriages between Catholics and other baptized persons have their own particular nature, but they contain numerous elements that could well be made good use of and developed, both for their intrinsic value and for the contribution that they can make to the ecumenical movement. This is particularly true when both parties are faithful to their religious duties. Their common Baptism and the dynamism of grace provide the spouses in these marriages with the basis and motivation for expressing their unity in the sphere of moral and spiritual values.
For this purpose, and also in order to highlight the ecumenical importance of mixed marriages which are fully lived in the faith of the two Christian spouses, an effort should be made to establish cordial cooperation between the Catholic and the non-Catholic ministers from the time that preparations begin for the marriage and the wedding ceremony, even though this does not always prove easy.
With regard to the sharing of the non-Catholic party in Eucharistic Communion, the norms issued by the Secretariat for Promoting Christian Unity should be followed.179
Today in many parts of the world marriages between Catholics and non-baptized persons are growing in numbers. In many such marriages the non-baptized partner professes another religion, and his beliefs are to be treated with respect, in accordance with the principles set out in the Second Vatican Council’s Declaration Nostra ætate on relations with non-Christian religions. But in many other such marriages, particularly in secularized societies, the non-baptized person professes no religion at all. In these marriages there is a need for Episcopal Conferences and for individual Bishops to ensure that there are proper pastoral safeguards for the faith of the Catholic partner and for the free exercise of his faith, above all in regard to his duty to do all in his power to ensure the Catholic baptism and education of the children of the marriage. Likewise the Catholic must be assisted in every possible way to offer within his family a genuine witness to the Catholic faith and to Catholic life.
