Big picture, it would be hard to over-state the impact of the U.S. Supreme Court’s legalization of same-sex marriage upon believers who uphold longstanding religious tradition. The resulting soul-searching is a theme worth careful journalistic treatment going forward.

One fruitful avenue would be seeking reactions from prime sources to three future options proposed by a package of articles in the current issue of Christianity Today, the influential evangelical monthly.

The cover offers a degree of optimism: “Have No Fear: How to Flourish in a Time of Cultural Weakness.”

That’s the tone of the lead article by two authors better known for politics than religion, Washington Post columnist Michael Gerson and Peter Wehner of the Ethics and Public Policy Center. Both were speechwriters and then top policy advisors in the George W. Bush White House. Armed with a foundation grant, they interviewed many evangelical writers, academicians and non-profit leaders, with varied reactions, then drew their own conclusions.

Gerson and Wehner scan history, noting how rarely authentic Christians have exercised full political power. Key quote: “When Christians find themselves on the losing side of Supreme Court decisions, it isn’t cause for despair. Nor does it preclude them from doing extraordinary things.”

Realistically, they say, believers must simply adjust to a world of same-sex marriage. Any bids to reverse this culture shift “will be spectacularly unsuccessful.” But “this does not mean they have to endorse gay marriage.” Traditionalists must remain vigilant in protecting “vital religious liberty,” which is a mark of the healthy society.
