Amoris Laetitia
Vatican II - citing Evangelii Guadium - the Gospel message should always resound; the core of that message, the kerygma, is what is "most beautiful, most excellent, most appealing and at the same time most necessary."(50)
St. JPII's Familiaris Consortio - the call and demands of the Spirit resound in the events of history...the Church can also be guided to a more profound understanding of the inexhaustible mystery of marriage and the family (8)
Pope Benedict's Dues Caritas Est - Doesn't the Church...blow the whistle just when the joy which is the Creator's gift offers us a happiness which itself a certain foretaste of the Divine? (142)
