About one in four Americans (27%) is intentionally sharing their married life with someone whose religious belief system is different from their own. If difference within traditions like Protestantism is included, the number jumps to 37%. This emerging trend is consistent with the generally agreed-upon trajectory of our culture. We are moving into a period of intense plurality. Difference—in all its forms—is pushing its way into the lives, churches, schools, and neighborhoods of Americans.
As people face these new experiences they often look for resources to help them navigate their new reality. This has produced what the Huffington Post calls a “mini-boom of guides to interfaith marriage and family.” A case in point is J. Dana Trent’s recently released book, Saffron Cross: The Unlikely Story of How a Christian Minister Married a Hindu Monk.
Trent’s book describes how she—a Baptist minister—met and fell in love with Fred Eaker, a practicing Hindu. The rapid increase in interfaith marriage poses a significant pastoral challenge for the Christian church. It’s important to remember that this is not the first time in which the Christian church has had to engage in pastoral and theological reflection on the nature of marriage and of marriage to those who are outside the household of faith.
The early church developed in the context of a pluralistic culture where, much like today, the cardinal virtue was theistic inclusivity. Greco-Roman culture was willing to welcome new gods as long as they could be incorporated into the already recognized deities. We see from St. Paul’s interaction with the people of Athens that the Greeks were eager to learn of this “foreign deity” and this “new teaching” (Acts 17: 18, 19). Early Christianity was quite comfortable in communicating the message of Christ to those who had yet to experience it.
As Paul addressed problems that arose in the churches under his apostolic care, he found it necessary to give the following counsel to the church at Corinth, “Do not be mismatched with unbelievers. For what partnership have righteousness and iniquity?” (2 Co. 6:14ff.).
This verse is often used to warn against the dangers of marrying someone of another faith. And the warning is likely well heeded. Yet, it’s also likely that Paul here is speaking more broadly than simply of matrimony.
