From Unitarian Roots to Multifaith Vision: Four Historical Highlights Between HDS and Unitarian Universalism

As the American Unitarian Association marks its 200th anniversary, a look at the deep and evolving ties between Unitarian Universalism and Harvard Divinity School. 

Since its founding in 1816, Harvard Divinity School (HDS) has been closely intertwined and shaped by many of the same figures, ideas, and commitments that defined the early Unitarian movement in the United States.  

In April 2026, the Harvard Divinity School Library hosted a panel discussion marking the 200th anniversary of the American Unitarian Association (AUA), one of the founding organizations that shaped the Unitarian Universalist Association today, bringing together faculty, students, and staff to reflect on this history.  

From their Unitarian origins to their present-day multifaith identities, HDS and Unitarian Universalism (UU) have developed in parallel—what Dan McKanan, Ralph Waldo Emerson Unitarian Universalist Association Senior Lecturer in Divinity, describes as a “sibling relationship that has taken new form in every generation.” 

Liberal Religion and the Founding of HDS

In the early nineteenth century, liberal religious thought was already gaining influence at Harvard. The 1805 election of Henry Ware Sr., a minister in the tradition that would soon be known as Unitarianism, signaled a shift toward a more open and less doctrinal approach to theology. That shift deepened in 1810, when John Thornton Kirkland—who preached a nondogmatic, ethical religion—became president of Harvard University.

In 1816, HDS was established as the first non-denominational divinity school in the United States. Though the new school was formally committed to free inquiry, it was shaped in its early years by Unitarian leadership, funding, and students preparing for ministry. As McKanan notes, the founders shared a commitment to a “learned ministry,” grounded in deep intellectual training and open to change over time.

Even as it took shape, HDS existed in a creative tension between nonsectarian ideals and Unitarian influence. The School was never under direct denominational control, and many of its founders—most notably William Ellery Channing—were ambivalent about formal denominational structures and committed to a broader vision of religious inquiry.

Challenging Tradition and Expanding Possibility

In 1838, Ralph Waldo Emerson delivered his Divinity School Address in Divinity Hall, often seen as a turning point in both Unitarianism and the history of HDS. His critique of “historical Christianity” challenged the tradition and, over time, helped reshape approaches to theological education. As Emerson argued in the address, “The intuition of the moral sentiment is an insight of the perfection of the laws of the soul.”

According to McKanan, Emerson’s ideas also clarified that a divinity school need not prepare students for a single professional path—a vision that continues to shape the wide range of vocations HDS students pursue today.

Broadening the School’s Religious Landscape

In the years following the Civil War, HDS began to expand in new directions. Unitarian minister Henry Whitney Bellows reorganized the denomination and led the School’s first major capital campaign, an effort that had lasting institutional impact.

As McKanan explains, the campaign helped make HDS more pluralistic by funding new professorial chairs held by scholars trained in other traditions, including a Southern Baptist seminary. Their work, in turn, contributed to the expansion of Jewish studies at Harvard, signaling a broader shift in the School’s intellectual and religious scope.

By the turn of the twentieth century, HDS continued to broaden its reach. Charles Eliot’s long tenure as Harvard president coincided with his son Samuel Atkins Eliot II’s leadership of the American Unitarian Association. Though both were deeply rooted in Unitarianism, they also sought to bridge divisions with other Protestant traditions.

Their efforts helped lead to the construction of Andover Hall (now Swartz Hall) in 1911 and to an increase in mainline Protestant students at HDS, further diversifying the School’s community.

A Shared History, A Multifaith Present

In 1967, the Harvard Divinity School Library became the official archive for the archives of the Unitarian Universalist Association, the Unitarian Universalist Service Committee, and Beacon Press. This development reflected the enduring institutional connection between HDS and Unitarian Universalism. Today, the Library’s collections continue to draw scholars from around the world, making HDS a central site for the study of Unitarian Universalism.  

According to McKanan, “both HDS and Unitarian Universalism embraced a multifaith identity around the turn of the twenty-first century,” a shift that continues to shape both institutions today. Just as HDS prepares students for scholarship and leadership across religious traditions, many UU congregations include Buddhists, pagans, Jews, humanists, and liberal Christians alongside one another.  

When McKanan was named the inaugural Ralph Waldo Emerson Unitarian Universalist Association Chair of Divinity in 2008, the appointment reflected the ongoing relationship between the School and the UU tradition. The “sibling relationship” between HDS and Unitarian Universalism, he says, continues to take new forms in every generation.
