410 Part Two gives them the strength to take up their crosses and so follow him, to rise again after they have fallen, to forgive one another, to bear one another’s burdens, to “be subject to one another out of reverence for Christ,” 150 and to love one another with supernatural, tender, and fruitful love. In the joys of their love and family life he gives themhere on earth a foretaste of the wedding feast of the Lamb: How can I ever express the happiness of a marriage joined by the Church, strengthened by an offering, sealed by a blessing, announced by angels, and ratified by the Father? . . . How wonderful the bond between two believers, now one in hope, one in desire, one in discipline, one in the same service! They are both children of one Father and servants of the same Master, undivided in spirit and flesh, truly two in one flesh. Where the flesh is one, one also is the spirit. 151 V. T he G oods and R equirements of C onjugal L ove 1643 “Conjugal love involves a totality, in which all the ele- ments of the person enter—appeal of the body and instinct, power of feeling and affectivity, aspiration of the spirit and of will. It aims at a deeply personal unity, a unity that, beyond union in one flesh, leads to forming one heart and soul; it demands indissolubility and faithfulness in definitive mutual giving; and it is open to fertility. In a word it is a question of the normal characteristics of all natural conjugal love, but with a new significance which not only purifies and strengthens them, but raises them to the extent of making them the expression of specifically Christian values.” 152 The unity and indissolubility of marriage 1644 The love of the spouses requires, of its very nature, the unity and indissolubility of the spouses’ community of persons, which embraces their entire life: “so they are no longer two, but one flesh.” 153 They “are called to grow continually in their communion through day-to-day fidelity to their marriage promise of total mutual self-giving.” 154 This human communion is confirmed, pu- rified, and completed by communion in Jesus Christ, given through the sacrament of Matrimony. It is deepened by lives of the common faith and by the Eucharist received together. 150 Eph 5:21; cf. Gal 6:2. 151 Tertullian, Ad uxorem. 2, 8, 6-7: PL 1, 1412-1413; cf.
