One of the issues before the WC's General Conference is whether to expand its membership boundary on divorce to allow for divorce in the case of spousal abuse. I don't know which way the wind will blow, but I did think I would sketch what I see the main options are:
1. The Legal Vote
Those who approach the biblical text more in terms of specific instructions will tend not to support the change because the New Testament does not mention spousal abuse as an appropriate basis for divorce. Mark gives no exceptional circumstance for divorce, and Matthew gives only one (sexual immorality), so the legal approach to the Bible would not likely allow for any additional reasons.
2. The Principle Vote
Those who approach the biblical text more in terms of general principles rather than specifics might put the Bible's teaching on divorce into the context of loving one's neighbor (in this case, one's spouse) and therefore not throwing your spouse away. If this is the reason for the prohibition (rather than violation of some abstract law), then it would at least seem that divorcing a truly abusive spouse does not in any way violate the principle of love of one's neighbor.
3. The Slippery Slope View
This view doesn't necessarily have a problem with allowing divorce in the case of true spousal abuse. It's problem is with the next exception that might come up at the next General Conference. There might also be the sense that some will claim spousal abuse to get out of marriage when in fact they're not really being abused.
4. The Practical Repercussions View
The slippery slope view would fall into this category. Someone might also argue that allowing for divorce in this case would have bad practical repercussions in some way. How hard would it be legally to defend removing someone from the membership rolls if they took you to court because a church did not truly believe a spouse was being sufficiently abused? Maybe someone would argue that it can't be allowed to maintain the integrity of the "pro-marriage system," regardless of how justified it might be in an individual situation.
Those are the different angles I thought of. Can you think of other positions?
