"Being rooted in the personal and total self-giving of the couple, and being required by the good of the children, the indissolubility of marriage finds its ultimate truth in the plan that God has manifested in His revelation: He wills and He communicates the indissolubility of marriage as a fruit, a sign and a requirement of the absolutely faithful love that God has for man and that the Lord Jesus has for the Church." Oct. 15, 2000

Excerpts Pontifical Council for the Family "Children, Springtime of the Family and Society"
What is needed then is for human societies, and the families who live within them, often in a context of struggle between the civilization of love and its opposites, to seek their solid foundation in a correct vision of man and of everything which determines the full "realization" of his humanity. Opposed to the civilization of love is certainly the phenomenon of so-called "free love"; this is particularly dangerous because it is usually suggested as a way of following one's "real" feelings, but it is in fact destructive of love. How many families have been ruined because of "free love"! To follow in every instance a ‘real’ emotional impulse by invoking a love "liberated" from all conditionings, means nothing more than to make the individual a slave to those human instincts which Saint Thomas calls "passions of the soul". "Free love" exploits human weaknesses; it gives them a certain "veneer" of respectability with the help of seduction and the blessing of public opinion. In this way there is an attempt to "soothe" consciences by creating a "moral alibi". But not all of the consequences are taken into consideration, especially when the ones who end up paying are, apart from the other spouse, the children, deprived of a father or mother and condemned to be in fact orphans of living parents.

Being rooted in the personal and total self-giving of the couple, and being required by the good of the children, the indissolubility of marriage finds its ultimate truth in the plan that God has manifested in His revelation: He [GOD] wills and He communicates the indissolubility of marriage as a fruit, a sign and a requirement of the absolutely faithful love that God has for man and that the Lord Jesus has for the Church."
