Brigham Young teaches that a religion that does not govern its members in their politics is "a very poor religion"; the Gospel unites people from different political backgrounds.

When we see a religion, and one which is claimed to be the religion of Christ, and it will not govern men in their politics, it is a very poor religion, it is very feeble, very taint in its effects, hardly perceptible in the life of a person. The religion that the Lord has revealed from heaven unites the hearts of the people, and when they gather together, no matter where they are from, they are of one heart and one mind. Those who have no idea of the effects of the Gospel attribute the oneness it produces to the influence of individuals now living on the earth, instead of giving God the glory, praise and honor.
The religion of heaven unites the hearts of the people and makes them one. You may gather a people together, and no matter how widely they differ in politics, the Gospel of Jesus Christ will make them one, even if among them were found members of all the political parties in the country, I do not know how many different political parties now exist in the country. There used to be only Federals and Democrats, then Whigs, Republicans, Locofocos, Barn-burners, and Free-soilers. Then the "Know Nothings" sprang into existence. I believe the Ku-Klux is a new political organization; and I have heard that, in the City of Washington, the Anti-Ku-Klux, another political party, has recently been organized. If members of all these various organizations were to obey the Gospel and gather together, the religion of heaven would clear their hearts of all political rubbish and make them one in voting for principles and measures, instead of men, and I think that any religion that will not do this is very feeble in its effects. The Christian religion, or what is called so, has failed to subdue the world; but what will the Gospel of Jesus Christ do? If the Gospel that we preach, and which we are trying to set before priest and people—for we want all to know and understand it—if it does not have the effect of convincing men and women of the truth sufficiently to induce them to yield obedience to its ordinances and to embrace the doctrine of life and salvation, and accept the overtures of mercy, learn Christ and obey him, it will drive them to the wall of infidelity. Do we believe this? It must be so. Do others believe it? No, they do not. The Christian world do not know that they are infidels in their belief in regard to the character of the Father and the Son, and the Holy Priesthood and its laws and requirements. If a man does not believe that he ought to be baptized for the remission of his sins, he is an infidel to baptism. My definition of the term infidel is that if any principle or doctrine is set before me, and I say I disbelieve it, I am neither more nor less than an infidel to that principle or doctrine. Are the sectarian world infidels according to this definition? Yes, and if we had time we would take some passages of Scripture and prove it. Take, for instance, the character of the Savior, and the sectarian world are infidel on this point. What do they believe about it? I do not know what they believe, and they do not know themselves. Many of them do not know that they believe anything. They would he glad to believe if they knew what to believe. But not knowing what to believe, they say, "We do not know, we do not understand, we cannot tell. We understand some things by reading the Scriptures; but the ministers tell us they have a spiritual meaning." Now what does this favorite saying of the ministers—"a spiritual meaning"—convey to the mind? Something or other that you and I do not understand, that is all.
