Do you have an unbelieving spouse?
Whereas, in times past persons have been permitted to gather with the Saints at Nauvoo, in North America—such as husbands leaving their wives and children behind; also, such as wives leaving their husbands, and such as husbands leaving their wives who have no children, and some because their companions are unbelievers. All this kind of proceedings we consider to be erroneous and for want of proper information. And the same should be taught to all the Saints, and not suffer families to be broken up on any account whatever if it be possible to avoid it. Suffer no man to leave his wife because she is an unbeliever. These things are an evil and must be forbidden by the authorities of the church or they will come under condemnation; for the gathering is not in hast nor by flight, but to prepare all things before you, and you know not but the unbeliever may be converted and the Lord heal him; but let the believers exercise faith in God, and the unbelieving husband shall be sanctified by the believing wife; and the unbelieving wife by the believing husband, and families are preserved and saved from a great evil which we have seen verified before our eyes. Behold this is a wicked generation, full of lyings, and deceit, and craftiness; and the children of the wicked are wiser than the children of light; that is, they are more crafty; and it seems that it has been the case in all ages of the world.
And the man who leaves his wife and travels to a foreign nation, has his mind overpowered with darkness, and Satan deceived him and flatters him with the graces of the harlot, and before he is aware he is disgraced forever; and greater is the danger for the woman that leaves her husband. The evils resulting from such proceedings are of such a nature as to oblige us to cut them off from the church.
And we also forbid that a woman leave her husband because he is an unbeliever. We also forbid that a man shall leave his wife because she is an unbeliever. If he be a bad man (i.e., the believer) there is a law to remedy that evil. And if the law divorce them, then they are at liberty; otherwise they are bound as long as they two shall live, and it is not our prerogative to go beyond this; if we do it, it will be at the expense of our reputation.
These things we have written in plainness and we desire that they should be publicly known,
