"False irenicism" or "false eirenism" is an expression used in certain 20th-century documents of the Catholic Church to criticize attempts at ecumenism that would allow Catholic doctrine to be distorted or clouded. Documents using the term include the encyclical "Humani generis", promulgated by Pope Pius XII in 1950, the Second Vatican Council's 1964 Decree on Ecumenism, "Unitatis Redintegratio," and Pope John Paul II's 1984 post-synodal apostolic exhortation, "Reconciliatio et paenitentia". Modern positive examples of Catholic non-false irenicism can be seen in the Document on Human Fraternity joint declaration of Pope Francis and Sheikh Ahmed el-Tayeb, and of Pope Benedict XVI's reported request for the Catholic church to participate in celebrations of the 500th anniversary of the Protestant Reformation in 2017.
