3. Jesus, in assuming human love, also perfected it (cf. GS, 49),
giving man and woman a new manner of loving, which has its
foundation in the irrevocable faithfulness of God. In light of this, the
Letter to the Ephesians has identified in the married love between a
man and a woman, “the great mystery” which makes present in this
world the love between Christ and the Church (cf. Eph 5:31-32). A
married couple possesses the charism (cf. 1 Cor 7:7) of building up
the Church with their spousal love and the task of the procreation and
rearing of children. United in an indissoluble sacramental bond, the
spouses live the beauty of love, fatherhood and motherhood and the
dignity of participating, in this way, in God's creative work.
