The apostle Paul was never married, yet gave marital advice.
it reminds me of the GB, who, for the majority, don't have children, yet give advice on child rearing. They also give advice on field service when they themselves rarely go, if ever.
headship, submission -- bah! As a female totally-believing-it-all good little JW, all it made me do was learn how to be manipulative and passive-aggressive with my dear husband, who, thankfully, was much more balanced than I was in the JW world. I was a self righteous little bitch who controlled the tv, the family's recreation, anything we chose to read, watch, or do... All "submissively"' of course.
