Absoluteendangermentof spirituality also provides a basis for separation. The believer in a religiously divided home should do everything possible to take advantage of God’s spiritual provisions. But separation is allowable if an unbelieving mate’s opposition (perhaps including physical restraint) makes it genuinely impossible to pursue true worship and actually imperils the believer’s spirituality. Yet, what if a very unhealthy spiritual state exists where both mates are believers? The elders should render assistance, but especially should the baptized husband work diligently to remedy the situation. Of course, if a baptized marriage partner acts like an apostate and tries to prevent his mate from serving Jehovah, the elders should handle matters according to the Scriptures. If disfellowshipping takes place in a case involving absolute endangerment of spirituality, willful nonsupport, or extreme physical abuse, the faithful Christian who seeks a legal separation would not be going against Paul’s counsel about taking a believer to court.—1 Corinthians 6:1-8.
