What I gather from the Bible is that more is expected from mankind after Jesus' coming than before. That is why the definition of adultery was broadened to include lusting after a woman not just sexual relations, murder is no longer defined as just the act, but also the hate found in our hearts for another, and why we are now commanded to not just love our neighbor any longer--now we are to love our enemies too etc......
As far the definition of "marital unfaithfulness", I have never spent time researching it as it has not pertained to my life at this time and I am prayerful that it never will. I am only familiar with the traditional definition, but will not state that that is the only possible definition.
My sole point was to explain to this young man is the biblical reason I am confident in that allows for divorce and remarriage when two Christians are involved. I am not confident in any other reasons, so I will not explore any other reasons with him. If anyone else is confident in other reasons, feel free to explore them with this young man.
Since I have been married to the same man for 20 years, and it is both our first marriages, I have no personal need to research this subject at great length.
