Nauvoo, Illinois, is a small place on an out-of-the-way bend in the Mississippi River. It rates a footnote in American history because for about four years in the mid-1800s it seemed a safe haven for persecuted members of The Church of Jesus Christ of Latter-day Saints—Mormons.

But suddenly Nauvoo is relevant again because we in America still have not learned lessons that should have been learned there in the 1840s.

Mormons had been driven from Missouri under threat of extermination, in the dead of the winter of 1838-39 with only the clothes on their backs. The mob war against them had been tacitly approved in an extermination order issued by the state’s governor. There had been murders, robberies, rapes, and beatings, including the massacre at Haun’s Mill. No one was spared—not even children. Their leader had been imprisoned on trumped-up charges for which there was no evidence.

Fleeing eastward, they found haven, and sympathetic helpers, in Illinois. They built up the new city of Nauvoo, and members began to gather there. But by 1844 their relationship with neighbors had gone sour again. The reasons were social and political as well as religious. Politicians began to fear the power of Mormons voting as a bloc. Their Christian religious beliefs were unorthodox. Among other things, some of them practiced polygamy, believing they were following a command of God given through a prophet. Much of the information that was circulated about them was false—lies concocted by people who were

ignorant of their doctrine but wanted to turn public opinion against them. Their leader, Joseph Smith, was assassinated by a mob.

I have been reading a lot about Nauvoo lately because my wife and I will be spending some time there as missionaries. In a country that proclaims religious freedom, there is plenty of room for differing views on doctrine. Many Christians find reason not to accept LDS doctrine, and I would defend their right to do so. But facts from history leave little room to doubt that what happened to the Mormons of Nauvoo was unjust and criminal.

The federal government failed to protect them and their rights. State governments failed to protect them. They were driven out of the then-United States to the Great Salt Lake Valley. When that territory was annexed by the United States a short time later, the persecution over their beliefs continued until—again by the command of a prophet who received a revelation from God—they abandoned the practice of polygamy. Before that happened, enemies tried to destroy the Church with laws targeting their beliefs (beliefs that seem relatively tame now, in an era when courts are dealing with issues of same-sex marriage and gender by choice).

But all that persecution is past now, right?

Or does some of this sound familiar in light of current events?

Today, we still have religious minorities under attack because their beliefs are different. Demagoguery and unsubstantiated, bigoted rhetoric has given the hate-mongers in our society license to go after people they fear or dislike.

Christians, including Mormons, who hold to the belief that marriage is a sacred relationship between a man and a woman are under attack by those who see themselves as more enlightened and more sensitive to acceptable social norms. Many people cite religious freedom as they reject traditional beliefs about morality, yet they are willing to violate the freedom of others by trying to force them to accept ideas repugnant to their consciences.

People who hate don’t seem to need a reason to attack Judaism, and haters attack Muslims based on half-truths or falsehoods. What little I know of Islam suggests it is a religion of peace whose name has been hijacked by remorseless and sadistic criminals. In any case, barring or booting people from the United States based on the fact that they come from a predominantly Muslim country does not live up to the ideal of religious freedom we hold up for the world. Never mind that Christians are not given tolerant treatment or religious freedom in Muslim countries; this country espouses a higher standard. Let’s live up to it.

An attack on the religious freedom of any minority is an attack on the religious freedom of all of us. We do not have to agree on doctrine to agree that we each deserve the right to worship according to our own faith. Whether we call him God or Heavenly Father, Yahweh or Allah, our obligation of faith and obedience is to Him, and no one should interfere with that so long as our worship does not hurt anyone else.

One basic Mormon tenet is this: “We claim the privilege of worshipping almighty God according to the dictates of our own conscience, and allow all men the same privilege, let them worship how, where, or what they may” (Articles of Faith). No one need be a Mormon to accept that this is a fair expectation of religious freedom. I can easily live and work alongside those who believe and worship differently than I. We will no doubt find that we have much more in common than we knew.

So, back to the lessons of Nauvoo. Mormons were victimized, persecuted, and driven out in Missouri, then Illinois ostensibly over religious differences. Has that kind of persecution stopped in this country? No, not for religious minorities whose views are seen as incorrect by self-appointed arbiters of social norms, and not for those who are the targets of hate.

Neither those who hate nor those who impose politically correct theology actually believe in religious freedom. Their view is that it should apply to those who see things their way, or those who share their ethnic heritage or skin color. The haters and the politically correct are often in the same camp. In the name of orthodoxy or racial and ethnic purity, they are willing to forego tolerance. They let themselves believe that people who do not share their philosophy or their heritage don’t deserve or can’t be trusted to handle freedom of choice.

It’s time for those who truly cherish religious freedom to say, “Enough.”

It is long past time for those who say—with fingers crossed—that America stands for religious freedom to act like they really mean it.

It is time for religious freedom without qualifications—without this mental reservation: “if they believe and worship as I do.”
