Catholic and protestant dating
The Catholic person must uphold the obligation to preserve his or her own faith and “ensure the baptism and education of the children in the Catholic Church,” (Catechism of the Catholic Church, 1635).One of the reasons that the Church exists is to safeguard the souls of those in its care.In the above example the two people are baptized Christians of different confessions (or denominations), but a non-baptized person is not a part of the Christian family.When it involves someone who has not been baptized then the marriage requires an express dispensation from the bishop in order for the union to be considered valid.For a mixed-marriage between a Catholic and a non-Catholic to work well it is important that the couple embraces what is common between their respective faith traditions and “to learn from each other the way in which each lives in fidelity to Christ,” (Catechism of the Catholic Church, 1634).This can be very difficult and trying, but can be overcome by mutual respect.
In either case the disparities between faiths can lead to tension and gradually religious indifference.Even if a marriage is presumed valid, it is not also sacramental sacramental marriage until proven otherwise.Since sacraments cannot be broken, non-Catholic Christians need to have their prior unions investigated and their marriage bonds declared null to be free to validly marry again within the Catholic Church.The matter of mixed marriages has become a burning issue between Protestants and Roman Catholics in recent months.
Several leading representatives of twentieth-century Protestantism have publicly taken a strong stand against the papal policy which to all intents and purposes say, "We make all the rules for any marriage in which a Roman Catholic is a party." Most important among the published statements on such marriages is the 24-page tract, of August 2, 1945, carried a fine article, 'This Matter of Mixed Marriages," by Frank C. Lieutenant Colonel Ridecitif is a retired chaplain of the United States Army.
The short answer is that any time one man and one woman of legal age exchange consent (I do), the marriage is assumed to be valid until proved otherwise (even if neither is baptized) since we believe that "natural marriage" is written deep in the hearts of all men and women.
