In the case of where a father or mother or son or daughter is disfellowshiped, how should such person be treated by members of the family in their family relationship?-P. C., Ontario, Canada.
...
We are not living today among theocratic nations where such members of our fleshly family relationship could be exterminated for apostasy from God and his theocratic organization, as was possible and was ordered in the nation of Israel in the wilderness of Sinai and in the land of Palestine. "Thou shalt surely kill him; thy hand shall be first upon him to put him to death, and afterwards the hand of all the people. And thou shalt stone him to death with stones, because he hath sought to draw thee away from Jehovah thy God, . . . And all Israel shall hear, and fear, and shall do no more any such wickedness as this is in the midst of thee."-Deut. 13:6-11, AS.
Being limited by the laws of the worldly nation in which we live and also by the laws of God through Jesus Christ, we can take action against apostates only to a certain extent, that is, consistent with both sets of laws. The law of the land and God's law through Christ forbid us to kill apostates, even though they be members of our own flesh-and-blood family relationship. However, God's law requires us to recognize their being disfellowshiped from his congregation, and this despite the fact that the law of the land in which we live requires us under some natural obligation to live with and have dealings with such apostates under the same roof.
God's law does not allow a marriage partner to dismiss his mate because his mate becomes disfellowshiped or apostatizes. Neither will the law of the land in most cases allow a divorce to be granted on such grounds. The faithful believer and the apostate or disfellowshiped mate must legally continue to live together and render proper marriage dues one to the other. A father may not legally dismiss his minor child from his household because of apostasy or disfellowshiping, and a minor child or children may not abandon their father or their mother just because he becomes unfaithful to God and his theocratic organization. The parent must by laws of God and of man fulfill his parental obligations to the child or children as long as they are dependent minors, and the child or children must render filial submission to the parent as long as legally underage or as long as being without parental consent to depart from the home. Of course, if the children are of age, then there can be a departing and breaking of family ties in a physical way, because the spiritual ties have already snapped.
If children are of age and continue to associate with a disfellowshiped parent because of receiving material support from him or her, then they must consider how far their spiritual interests are being endangered by continuing under this unequal arrangement, and whether they can arrange to support themselves, living apart from the fallen-away parent. Their continuing to receive material support should not make them compromise so as to ignore the disfellowshiped state of the parent. If, because of acting according to the disfellowship order of the company of God's people, they become threatened with a withdrawal of the parental support, then they must be willing to take such consequences.
(Pretty scary stuff, huh?)
