Two French Protestant refugees in eighteenth-century Amsterdam gave the world an extraordinary work that intrigued and outraged readers across Europe. In this captivating account, Lynn Hunt, Margaret Jacob, and Wijnand Mijnhardt take us to the vibrant Dutch Republic and its flourishing book trade to explore the work that sowed the radical idea that religions could be considered on equal terms.

Famed engraver Bernard Picart and author and publisher Jean Frederic Bernard produced The Religious Ceremonies and Customs of All the Peoples of the World, which appeared in the first of seven folio volumes in 1723. They put religion in comparative perspective, offering images and analysis of Jews, Catholics, Muslims, the peoples of the Orient and the Americas, Protestants, deists, freemasons, and assorted sects. Despite condemnation by the Catholic Church, the work was a resounding success. For the next century it was copied or adapted, but without the context of its original radicalism and its debt to clandestine literature, English deists, and the philosophy of Spinoza.

Ceremonies and Customs prepared the ground for religious toleration amid seemingly unending religious conflict, and demonstrated the impact of the global on Western consciousness. In this beautifully illustrated book, Hunt, Jacob, and Mijnhardt cast new light on the profound insight found in one book as it shaped the development of a modern, secular understanding of religion.

In the late 1800s, as Japanese leaders mulled over the usefulness of religion in modernizing their country, they chose to invite Unitarian missionaries to Japan. This book spotlights one facet of debates sparked by the subsequent encounter between Unitarianism and Buddhism—an intersection that has been largely neglected in the scholarly literature. Focusing on the cascade of events triggered by the missionary presence of the American Unitarian Association on Japanese soil between 1887 and 1922, Michel Mohr’s study sheds new light on this formative time in Japanese religious and intellectual history.

Drawing on the wealth of information contained in correspondence sent and received by Unitarian missionaries in Japan, as well as periodicals, archival materials, and Japanese sources, Mohr shows how this missionary presence elicited unprecedented debates on “universality” and how the ambiguous idea of “universal truth” was utilized by missionaries to promote their own cultural and ethnocentric agendas. At the turn of the twentieth century this notion was appropriated and reformulated by Japanese intellectuals and religious leaders, often to suit new political and nationalistic ambitions.
