The Defence of the Seven Sacraments (in Latin, Assertio Septem Sacramentorum) is a theological treatise from 1521, written by King Henry VIII of England. Henry started to write it in 1519 while he was reading Martin Luther's attack on indulgences. By June of that year, he had shown it to Thomas Wolsey, but it remained private until three years later, when the earlier manuscript became the first two chapters of the Assertio, the rest consisting of new material relating to Luther's De Captivitate Babylonica. It is believed that Thomas More was involved in the composition of the piece. Author J. J. Scarisbrick describes the work as "one of the most successful pieces of Catholic polemics produced by the first generation of anti-Protestant writers." It went through some twenty editions in the sixteenth century and, as early as 1522, had appeared in two different German translations. It was dedicated to Pope Leo X, who rewarded Henry with the title Fidei Defensor (Defender of the Faith) in October 1521 (a title revoked following the king's break with the Catholic Church in the 1530s, but re-awarded to his heir by the English Parliament).

The Defence of the Seven Sacraments (in Latin: Assertio Septem Sacramentorum) is a theological treatise published in 1521, written by King Henry VIII of England, allegedly with the assistance of Thomas More. The extent of More's involvement with this project has been a point of contention since its publication.Henry started to write it in 1519 while he was reading Martin Luther's attack on indulgences. By June of that year, he had shown it to Thomas Wolsey, but it remained private until three years later, when the earlier manuscript became the first two chapters of the Assertio, the rest consisting of new material relating to Luther's De Captivitate Babylonica.Author J. J. Scarisbrick describes the work as "one of the most successful pieces of Catholic polemics produced by the first generation of anti-Protestant writers."[1] It went through some twenty editions in the sixteenth century and, as early as 1522, had appeared in two different German translations.It was dedicated to Pope Leo X, who rewarded Henry with the title Fidei Defensor (Defender of the Faith) in October 1521 (a title revoked following the king's break with the Catholic Church in the 1530s, but re-awarded to his heir by the English Parliament).Luther's reply to the Assertio (Against Henry, King of the English) was, in turn, replied to by Thomas More, who was one of the leaders of the Catholic humanist party in England (Responsio ad Lutherum).

For writing this book, King Henry VIII was named Defender of the Faith by Pope Leo X. When out of lust, Henry fell into schism from the Catholic Church he unjustly retained the title of defender of a faith he had now abandoned. In this book he defends the seven sacraments, now diluted by the Anglican Church he had started. He also defends the primacy of the Roman Pontiff, he who was soon to refuse to obey in a matter of morals in regard to the Sacrament of Matrimony.

In 1588, the Spanish Jesuit Pedro de Ribadeneyra published a history of the English Reformation, which he continued to revise until his death in 1611. Spencer J. Weinreich’s translation is the first English edition of the History, one fully alive to its metamorphoses over two decades. Weinreich’s introduction explores the text’s many dimensions—propaganda for the Spanish Armada, anti-Protestant polemic, Jesuit hagiography, consolation amid tribulation—and assesses Ribadeneyra as a historian. The extensive annotations anchor Ribadeneyra’s narrative in the historical record and reconstruct his sources, methods, and revisions. The History, long derided as mere propaganda, emerges as remarkable evidence of the centrality of historiography to the intellectual, theological, and political battles of early modern Europe.
