Re they "lived in sexual sin" during Rutherford's era.
Wonder how they, GB, are going to handle the current Australian law whereby couples can merely register their relationship. No ceremony, just a signing of names etc. The result being a legal relationship with all entitlements to property etc.
My guess is that most Jw's will still opt for the traditional wedding but the odd one or two may take the current option.
