If an individual is disfellowshiped, but continues in quiet attendance at the Kingdom Hall, is it proper for that one’s marriage mate to sit with such a one during the meetings?—J. F., Switzerland.
With a view to helping sincerely repentant ones to get back into proper relationship with Jehovah God and his organization, it has been the policy of the Society to permit disfellowshiped persons to be present at all meetings at the Kingdom Hall that are open to the general public. For married persons Jesus set out the proper viewpoint when he said: “Did you not read that he who created them at the beginning made them male and female and said: ‘For this reason a man will leave his father and his mother and will stick to his wife, and the two will be one flesh’? So that they are no longer two, but one flesh. Therefore, what God has yoked together let no man put apart.” (Matt. 19:4-6) This rule would seem to apply at the Kingdom Hall as well as elsewhere. In view of this it would seem to be improper to force a separation between a man and his wife even if one or the other is disfellowshiped. This is not having fellowship spiritually on the part of the faithful one with the disfellowshiped partner. However, it would be wrong for the individual who is in good standing to try to force the company of the disfellowshiped mate upon the other brothers and sisters in the congregation in the endeavor to have them recognize the disfellowshiped one and have communion with that one.
