During the
French Third Republic, which began in 1870, the power and influence of French Catholicism steadily declined. The French government passed laws bearing more and more stringently on the Catholic church, and the majority of French citizens did not object. Indeed, they began to look toward legislators and not to the clergy for guidance. Observing this, and encouraged by the action of
Pope Leo XIII, who in 1892 called on French Catholics to accept the Republic, several young French priests set themselves to stop the decline in church power. They determined that because the church was predominantly sympathetic to the monarchists and hostile to the Republic, and because it held itself aloof from modern philosophies and practices, people had turned away from it. Some progressive priests believed that the church had not adapted to modern needs. They began a domestic apostolate which had for one of its rallying cries, ("Let us go to the people"). They agitated for social and philanthropic projects, for closer contacts between priests and parishioners, and for general cultivation of personal initiative, both in clergy and in laity. They looked for inspiration to America, where they saw a vigorous church among a free people, with priests publicly respected, and with a note of aggressive zeal in every project of Catholic enterprise. Hecker had sought to reach out to Protestant Americans by stressing certain points of Catholic teaching, but Pope Leo XIII understood that effort as a watering down of Catholic doctrine. Hecker also had used terms such as "natural virtue", which to the pope suggested the
Pelagian heresy. Because members of the
Paulist Fathers took promises but not the vows of religious orders, many concluded that Hecker denied the need for external authority. The French liberals particularly admired Hecker for his love of modern times and modern liberty and his devotion to liberal Catholicism. Indeed, they took him as a kind of patron saint. Inspired by Hecker's life and character, the activist French priests undertook the task of persuading their fellow-priests to accept the political system, and then to break out of their isolation, put themselves in touch with the intellectual life of the country, and take an active part in the work of social
amelioration. In 1897, the movement received a new impetus when
Denis J. O'Connell, former rector of the
Pontifical North American College in Rome, spoke on behalf of Hecker's ideas at the Catholic Congress in
Fribourg.
Arthur Preuss (1871–1934), the foremost German American Catholic intellectual in the United States, was an outspoken enemy, filling his scholarly journal
Fortnightly Review with criticisms of Americanist theology. Many powerful Vatican authorities also opposed the "Americanist" tendency. Pope
Leo XIII was reluctant to chastise the American Catholics, whom he had often praised for their loyalty and faith. In 1899 he wrote Cardinal Gibbons, "It is clear ... that those opinions that, taken as a whole, some designate as 'Americanism' cannot have our approval." ==Suppression==
