The intellectual legacy of Manuel Lacunza rests upon an expansive theological treatise that circulated clandestinely across two continents long after the author’s death. Born in Santiago in 1731, this Chilean Jesuit philosopher spent his final years in Italian exile, producing dense arguments regarding biblical prophecy that defied the institutional constraints of the eighteenth-century Catholic Church.
Early Life and Academic Formation
Born into a family of merchants, Lacunza underwent his primary education at the Convictorio Carolino between 1741 and 1747. He joined the Society of Jesus in 1747 and later served as a professor of philosophy and grammar from 1755 to 1768. Following his ordination in 1766, he gained recognition in the Chilean capital as a skilled pulpit orator before political events forced his permanent relocation.

The 1767 expulsion of the Jesuits from Spanish territories by King Charles III sent Lacunza to Cádiz and eventually to Imola, Italy. Stripped of his priestly status by the 1773 papal bull Dominus ac Redemptor, he lived in isolation, supported by a companion he referred to as his good mulatto. This period of withdrawal facilitated an intensive, focused study of biblical prophecy and the Church Fathers, moving away from his previous academic pursuits.
The Millenarian Manuscript
By 1790, Lacunza completed his primary work, The Coming of the Messiah in Glory and Majesty. Written under the pseudonym Juan Josafat Ben-Ezra, the text challenged prevailing interpretations regarding the end of the world. Lacunza argued that the material earth would not perish, but rather undergo a transition into a thousand-year reign of peace. His failure to secure royal patronage for official publication did not stop the manuscript from circulating throughout South America.
Prohibition and Publication
The Inquisition repeatedly attempted to suppress Lacunza's writings, denouncing his millenarian views. Despite these efforts, unauthorized editions appeared in Cádiz, London, Paris, and Mexico between 1810 and 1826. In 1824, Pope Leo XII formally placed the work on the Index of Prohibited Books, citing concerns over its influence on the clergy. Lacunza died in 1801, his body discovered in a pit near Imola, seemingly following a solitary walk.
