From Pope St. John Paul II’s Apostolic Exhortation Familiaris Consortio (1981):
The sacrament of marriage is the specific source and original means of sanctification for Christian married couples and families. It takes up again and makes specific the sanctifying grace of Baptism. By virtue of the mystery of the death and Resurrection of Christ, of which the spouses are made part in a new way by marriage, conjugal love is purified and made holy: “This love the Lord has judged worthy of special gifts, healing, perfecting and exalting gifts of grace and of charity.”138
The gift of Jesus Christ is not exhausted in the actual celebration of the sacrament of marriage, but rather accompanies the married couple throughout their lives. This fact is explicitly recalled by the Second Vatican Council when it says that Jesus Christ “abides with them so that, just as He loved the Church and handed Himself over on her behalf, the spouses may love each other with perpetual fidelity through mutual self-bestowal. . . . For this reason, Christian spouses have a special sacrament by which they are fortified and receive a kind of consecration in the duties and dignity of their state. By virtue of this sacrament, as spouses fulfill their conjugal and family obligations, they are penetrated with the Spirit of Christ, who fills their whole lives with faith, hope and charity. Thus they increasingly advance towards their own perfection, as well as towards their mutual sanctification, and hence contribute jointly to the glory of God.”139
Christian spouses and parents are included in the universal call to sanctity. For them this call is specified by the sacrament they have celebrated and is carried out concretely in the realities proper to their conjugal and family life.140 This gives rise to the grace and requirement of an authentic and profound conjugal and family spirituality that draws its inspiration from the themes of creation, covenant, cross, resurrection, and sign, which were stressed more than once by the Synod.
Christian marriage, like the other sacraments, “whose purpose is to sanctify people, to build up the body of Christ, and finally, to give worship to God,”141 is in itself a liturgical action glorifying God in Jesus Christ and in the Church. By celebrating it, Christian spouses profess their gratitude to God for the sublime gift bestowed on them of being able to live in their married and family lives the very love of God for people and that of the Lord Jesus for the Church, His bride.
Just as husbands and wives receive from the sacrament the gift and responsibility of translating into daily living the sanctification bestowed on them, so the same sacrament confers on them the grace and moral obligation of transforming their whole lives into a “spiritual sacrifice.”142 What the Council says of the laity applies also to Christian spouses and parents, especially with regard to the earthly and temporal realities that characterize their lives: “As worshippers leading holy lives in every place, the laity consecrate the world itself to God.”143
