Anna Marina, ... remembering a case long ago... A pretty, young sister in my congregation, a daughter in a large JW family, fell in love with a “worldly boy”. They committed fornication, but wanted to be married. She confessed and repented, intending to marry him after confessing to the elders. The elders consulted the Society. The elders were willing to accept her repentance on condition that she not marry the “worldly boy”. Well... no. They were madly in love and wanted to be married. She married the young “worldly boy” and was immediately disfellowshipped for at least a year.
She wouldn’t otherwise have been disfellowshipped for marrying a “worldly boy”. But the Watchtower Society leveraged her sin of fornication into a way to keep her from marrying the “worldly boy”. When that didn’t work, they disfellowshipped her. Watchtower’s control over its members is complete. I, along with the rest of the congregation, didn’t speak to her until she was reinstated.
