Publication of Encyclical Testem Benevolentiae Nostrae

Pope Leo XIII
Time Period
In 1899, Pope Leo XIII issued the encyclical Testem Benevolentiae Nostrae, which was addressed to Cardinal James Gibbons of Baltimore and condemned the heresy of Americanism. The immediate cause of the encyclical was a French translation of a biography of American priest Isaac Hecker. Tensions between American and European church leaders, however, reached back further. Pope Leo criticized the supposed Americanist notions that the church should adapt to the times and that individual conscience should be the sole guide of people’s actions. The encyclical argued that Catholicism in the United States was not unique and that the church was changeless. Although not mentioned by name, it is evident that the theological and social thought of modernist-leaning clerics such as Isaac Hecker and John Ireland was being questioned by the Vatican. These modernists were quick to disclaim any of the condemned ideas, while their conservative opponents in the church praised the encyclical.
