ELEANOR’S QUESTION:

Is it sinful for Catholics to attend a wedding between a Catholic and a Jew, performed by a rabbi?

THE RELIGION GUY’S ANSWER:

No.

But there’s much more to be said about how Catholicism views interfaith marriages. (The church is more open on this than those who adhere to Jewish tradition, as we’ll discuss below.)

An official U.S. Catholic website says that until recent decades “the idea of a Catholic marrying outside the faith was practically unheard of, if not taboo,” and such ceremonies never occurred publicly in a church sanctuary. Yet today, in some parts of the U.S. up to 40 percent of Catholics are in “ecumenical marriages” between Christians of differing affiliations, or “interfaith marriages” with non-Christians.

The site says “because of the challenges that arise, . . . the church doesn’t encourage” interfaith marriage but does seek to support such couples and “help them to meet those challenges with a spirit of holiness.” Under the law code that covers all Catholics worldwide, says a Canon Law Society of America commentary, there’ve been “extensive changes” in the direction of leniency in marriage rules since the Second Vatican Council (1962-65) and mixed marriages have become “more commonplace and socially acceptable.”

In Catholic belief, a marriage between a Catholic and a Jew (or someone from another non-Christian religion) is not a “sacrament.” Importantly, this doesn’t mean the church questions that the couple is truly married as a civil matter, nor does it express any disrespect toward Judaism, with which Christianity has such great affinity.

The technical term used in marriages with non-Christians is “the impediment of disparity of cult.” If an interfaith couple wishes a wedding in a Catholic church, canon law prescribes that the local bishop must issue a “dispensation” on the basis of “just and reasonable cause,” which occurs far more routinely than in past times.
