There are many things we can “judge” (discern) as Christians, but we cannot judge if someone has lost their salvation, nor can we pronounce punishments as though they have.
We are allowed to punish bad behavior and to excommunicate people who appear to have crossed such lines, though.
Regardless, our vow to God remains if we were Christian.
If you’re spouse leaves you and shares a bed with another there is *zero* Biblical evidence binding you to that person there is, however, some Biblical indication that you are free to move on with your life..
Christian or not if a spouse leaves and weds another remarriage is Biblical. Prove me wrong...
