Members of the society of the Catholic Apostolate, founded at Rome in 1835 by St. Vincent Pallotti (1795-1850). Their purpose is to preach and teach the faith among Christians and non-Christians, and to co-operate among the faithful in the Catholic apostolate. The Pallottines, according to Pope Pius XI, were the forerunners of modern Catholic Action. There are also Pallottine Sisters, founded by St. Vincent in 1843 as a separate congregation. One of their main interests is to foster reunion of the Oriental separated Christians with Rome.
