I believe you are married until death of a partner. I view divorce as an attempt to break a vow which was vowed to only be broken once dead.
We commonly vow only two things as Christians. First, we make a vow/covenant with God through Christ in accepting and following Christ as our Savior. Second, we vow/covenant to our spouse.
It says a lot about a person when they attempt to break their vows.
I agree. One of the more bizarre things to me is the development of a general acceptance of divorce in the Christian community.
I may disagree with you in that I believe the Christian marriage can be broken by infidelity as well as by death.
