The family is the nucleus of society, and is the first hierarchical order in all of human history, established by Almighty God Himself, inscribed into the very Natural Law.
As such, the father, as head of the household, is a figure of God Himself - the Source of all authority. This should be obvious especially to us Catholics - we call priests "Father," we call the Pope the "Holy Father;" and the First Person of the Blessed Trinity is not merely "the Head" or "the First," but The Father - the Father par excellence whence all fatherhood and paternal authority is derived.
The enemies of the Church themselves recognize this in their own wicked way. Freud twisted this self-evident truth into the notion that God is a mere psychological / sociogigcal construct that amounts to little more than a primitive, childish memory of one's father, and the sound of his authoritative voice ringing in the ears throughout one's life (and the life of man as a whole). This, incidentally, is proof of the diabolism of these materialist hucksters - they, like their father the devil - take the truth, invert it, and sell it back to us.
Likewise, the sodomite "marriage" agenda; feminism; divorce; pornography; the general mockery of men in popular culture - all of these are, to one degree or another, attacks on fatherhood, and an attack on fatherhood is always an attack on Almighty God Himself. It's only natural that all manner of evils should result from these attacks, the first and foremost being that abominable, unnatural rejection of God Almighty, fount of all Fatherhood - atheism.
