Asked about “freedom to remarry” for the “guilty” or “innocent” party after a divorce for sexual sin, Dr. Don Carson responds:
“There are some people that say that only the innocent party does have the right to remarry. I find it difficult to think of a Biblical text that sanctions that. That is to say, when the sexual union is broken, the sexual union is broken. And history that’s been a pretty centrist position, too. John Murray, for example, insists on that. So you still want to make sure there’s repentance, that there’s genuine conversion and all, yeah, yeah, yeah, I understand all that. But at the same time I don’t think that remarriage after ‘pornea‘ is a concessive option only for the so-called ‘non-guilty’ party. I don’t think that correct.”
