Under what specific circumstances does a bishop give consent to disparity of cult marriages?

Excellent question! For context, the “disparity of cult” in question here refers to when two people of different faiths attempt to get married. The term refers very specifically to when a Catholic wishes to marry an unbaptized non-Christian (a Muslim, a Hindu, an atheist, etc.). When a Catholic attempts to marry a baptized person who is not Catholic, the Church refers to this as a “mixed marriage.” Mixed marriages require the bishop to give permission, but they do not require a dispensation.

The difference between marrying a baptized non-Catholic and an unbaptized non-Christian is pretty significant in the eyes of the Church. Although we have differences in belief with other Christians, their Baptism is still (generally) valid, so although they are not Catholic, they are still fellow members of the Body of Christ (albeit lacking the fullness of the faith and the sacraments which we possess as Catholics). When it comes to those of entirely different faiths, however, they are not members of the Body of Christ through Baptism. This does not mean they lack the same human dignity we all share as human beings, but receiving the grace of the sacraments (marriage and otherwise) requires the sacramental grace of Baptism. Put simply, unbaptized persons cannot receive grace from the sacraments. That means that under normal circumstances, if a couple had disparity of cult (also called “disparity of worship”) and attempted marriage, the marriage would be invalid. This doesn’t mean it was just a marriage without the Church’s approval (that would just be illicit, meaning “not in accord with the Church’s law”). An invalid marriage means that no sacrament of marriage took place at all. Why? Because, as mentioned, an unbaptized person cannot receive the sacraments!

This explains why there is more caution and discernment when a couple with a disparity of cult approaches the Church and asks for marriage. Marriage is a serious commitment in the eyes of the Church because it is a sacrament which is directed toward the eternal salvation of the husband and the wife. It is also directed toward the upbringing of their children in the faith. When there is a disparity of cult, both of these objectives become more challenging. The Church wants couples discerning marriage to understand that seriousness–and therefore requires that the bishop give a dispensation to a couple with this disparity.

There is not a specific list of circumstances where a bishop will approve or disapprove this kind of dispensation. It is more guided by the principles we mentioned above. Some helpful questions here would be:

• Are both husband and wife serious about their marital commitment?
• Does the non-Christian party understand the meaning of marriage in a Catholic sense as a lifelong and unbreakable commitment?
• Does the non-Christian party pledge to let the children be raised in the Catholic faith?
• Is it clear that this marriage is for the good of both spouses?

These are the kinds of questions that a bishop would want to have answers for. Bishops frequently rely on help from a priest counseling the couple or sometimes a marriage tribunal for more feedback. The Church does not want to deny marriage to anybody, but she also doesn’t want to allow a marriage that will not be fruitful for the spouses!

All of this should highlight the sacredness of marriage in the Catholic Church. The Church gives freedom to everyone to discern their vocation; however, the Church also has a responsibility to care for each person’s spiritual well-being. A marriage to a non-Catholic (and even more so to a non-Christian) comes with its own challenges. That does not diminish the love the couple shares with one another, but it is so important that the couple understands the seriousness of what they are asking and what it means for the future they desire to share.
