Assertio Septem Sacramentorum (Defense of the Seven Sacraments)

Summary

Henry VIII's *Assertio Septem Sacramentorum* defends the Catholic Church's seven sacraments against Martin Luther's criticisms, asserting the validity of each as divine institutions. The central thesis is that the seven sacraments (Baptism, Confirmation, Holy Eucharist, Penance, Extreme Unction, Holy Orders, and Matrimony) are indeed divinely instituted and essential for salvation. Henry argues that Luther's reduction of sacraments to only Baptism and the Eucharist is erroneous and undermines the authority of the Church and established doctrine.

The book's main ideas include theological arguments for the scriptural and traditional basis of each sacrament, detailed refutations of Luther's specific points, and a defense of the priesthood and the Eucharist as central to Christian life. Readers gain an understanding of the theological controversies of the Reformation from a pro-Catholic, royal perspective and witness Henry VIII's early defense of traditional doctrine before his break with Rome.
