This question is no longer as hypothetical as it used to be for Americans.
Here are three helpful resources:
- D. A. Carson, “The SBJT Forum: To handle certain categories of divorce and remarriage cases within the congregation, some churches have established a kind of ‘ecclesiastical court.’ What biblical warrant, if any, exists for this practice?” The Southern Baptist Journal of Theology 6, no. 1 (2002): 104–7. See point 1 on pp. 105–6.
- D. A. Carson, “Counsel to a Young Church Planter on Marriage” (December 5, 2009). See point 5.
- Collin Hansen, ed., “TGC Asks: Should pastors separate the Christian wedding ceremony from the civil rite?” (August 6, 2010). Four pastors weigh in: Steve Dewitt, Ryan Kelly, Jay Thomas, and Bob Bixby.
