Although the Bible makes a clear distinction between true and false teachings, God allows each person the freedom to choose how he or she will respond. (Deuteronomy 30:19, 20) No one should be forced to worship in a way that he finds unacceptable or be made to choose between his beliefs and his family. Does study of the Bible lead to family breakup? No. In fact, the Bible encourages a husband and wife who practice different religions to remain together as a family.—1 Corinthians 7:12, 13.
This only applies to 'other' religions of coarse. Don't you love Satan's, I mean the GB's, concluding spindoctoring phrase about breaking up families. Even though this is geared towards those who are of other faiths who have heard that joining JW's means no more associating with non jw relatives, no holidays, or shunning those who leave, they say no we don't break up familes, if 2 are married they are to remain married. The snake like GB know full well they are being deceptive.
