59. The Church prays for the Christian family and educates the family to live in generous accord with the priestly gift and role received from Christ the High Priest. In effect, the baptismal priesthood of the faithful, exercised in the sacrament of marriage, constitutes the basis of a priestly vocation and mission for the spouses and family by which their daily lives are transformed into "spiritual sacrifices acceptable to God through Jesus Christ."(149) This transformation is achieved not only by celebrating the Eucharist and the other sacraments and through offering themselves to the glory of God, but also through a life of prayer, through prayerful dialogue with the Father, through Jesus Christ, in the Holy Spirit.
Family prayer has its own characteristic qualities. It is prayer offered in common, husband and wife together, parents and children together. Communion in prayer is both a consequence of and a requirement for the communion bestowed by the sacraments of Baptism and Matrimony. The words with which the Lord Jesus promises His presence can be applied to the members of the Christian family in a special way: "Again I say to you, if two of you agree on earth about anything they ask, it will be done for them by my Father in heaven. For where two or three are gathered in my name, there am I in the midst of them."(150)
Family prayer has for its very own object family life itself, which in all its varying circumstances is seen as a call from God and lived as a filial response to His call. Joys and sorrows, hopes and disappointments, births and birthday celebrations, wedding anniversaries of the parents, departures, separations and homecomings, important and far-reaching decisions, the death of those who are dear, etc.-all of these mark God's loving intervention in the family's history. They should be seen as suitable moments for thanksgiving, for petition, for trusting abandonment of the family into the hands of their common Father in heaven. The dignity and responsibility of the Christian family as the domestic Church can be achieved only with God's unceasing aid, which will surely be granted if it is humbly and trustingly petitioned in prayer.
