Conservative opponents of same-sex marriage have long used the slippery-slope argument: If states are permitted to let two men or two women marry, then what’s to stop them from giving the same privilege to two men and one woman, or two women and one man? Or six? Or 12? Once you legitimize same-sex marriage, sociologist Peter Berger wrote on his blog in 2011, “you open the door to any number of other alternatives to marriage as a union of one man and one woman: polygamous (an interesting question for Muslims in Germany and dissident Mormons in Arizona), polyandrous, polygenerational – perhaps polyspecies?” The Unitarians are so liberal that they’re playing right into conservative hands.

 
The joke about Unitarians is that they’re where you go when you don’t know where to go. Theirs is the religion of last resort for the intermarried, the ambivalent, the folks who want a faith community without too many rules. It is perhaps no surprise that the Unitarian Universalist Association is one of the fastest-growing denominations in the country, ballooning 15 percent over the past decade, when other established churches were shrinking. Politically progressive to its core, it draws from the pool of people who might otherwise be “nones” – unaffiliated with any church at all.

But within the ranks of the UUA over the past few years, there has been some quiet unrest concerning a small but activist group that vociferously supports polyamory. That is to say “the practice of loving and relating intimately to more than one other person at a time,” according to a mission statement by Unitarian Universalists for Polyamory Awareness (UUPA). The UUPA “encourages spiritual wholeness regarding polyamory,” including the right of polyamorous people to have their unions blessed by a minister.

UUA headquarters says it has no official position on polyamory. “Official positions are established at general assembly and never has this issue been brought to general assembly,” a spokeswoman says.

But as the issue of same-sex marriage heads to the Supreme Court, many committed Unitarians think the denomination should have a position, which is that polyamory activists should just sit down and be quiet. For one thing, poly activists are seen as undermining the fight for same-sex marriage. The UUA has officially supported same-sex marriage, the spokeswoman says, “since 1979, with tons of resolutions from the general assembly.”
