3An internationally respected Roman Catholic leader on the mystery-sacrament of marriageMarriage and the family are at the forefront of the burning questions being debated by civil society and the church today. Cultural changes in our increasingly secularized society have dire consequences in the family sphere, requiring a Christian response that is faithful to the Church's tradition, says Marc Cardinal Ouellet.In Mystery and Sacrament of Love Ouellet clearly expounds a theology of marriage and the Catholic Church's understanding of the sacrament celebrated between spouses and God. Developed with influences from Pope Francis, the theological intuitions of Vatican II, the contributions of Saint John Paul II (the "pope of the family"), and the innovative thought of Hans Urs von Balthasar, Ouellet's study lays the foundations for a faithful resurgence of well-being for families in our contemporary day and age.
