Introduction
When married love is lived in its most authentic nature, it is expressed in all life situations, becoming a witness, proclaiming and realizing the Kingdom of God: "It is in married and family love... that the Christian family's participation in the prophetic, priestly and kingly mission of Christ and his Church finds expression and realisation. Therefore, love and life constitute the nucleus of the saving mission of the Christian family in the Church and for the Church"(Familiaris Consortion [FC].50). The conjugal love of the spouses is fully expressed in fatherhood and motherhood, the fruit of their love, which makes them co-responsible for the gift of life, by protecting, developing, educating and evangelizing: "Christian couples are, for each other, for their children and for their relatives, co-operators of grace and witnesses of the faith. They are the first to pass on the faith to their children and to educate them in it. By word and example they form them to a Christian and Apostolic life"
