I've seen two schools of thought on this. One says that there should be a visible repentance of cohabitation before a pastor officiates over the marriage ceremony. Others maintain that it would be unlawful to forbid marriage from the couple, since doing so is not instructed explicitly in Scripture nor in the Confession. I'd like to get your input on this, as I have an unsaved couple requesting that I officiate at their wedding. Up until now, for couples in this circumstance, my wedding policy has asked for a time of evidential repentance of the sin of cohabitation. However, I want to rethink this and make sure that I am not exceeding Scripture and Confession. Thanks!
