From G. K. Chesterton in The Everlasting Man:
We can say that the family is the unit of the state; that it is the cell that makes up the formation. Round the family do indeed gather the sanctities that separate men from ants and bees. Decency is the curtain of that tent; liberty is the wall of that city; property is but the family farm; honour is but the family flag.
If we are not of those who begin by invoking a divine Trinity, we must none the less invoke a human Trinity; and see that triangle repeated everywhere in the pattern of the world. For the highest event in history, to which all history looks forward and leads up, is only something that is at once the reversal and the renewal of that triangle. …The old Trinity was of father and mother and child and is called the human family. The new is of child and mother and father and has the name of the Holy Family. It is in no way altered except in being entirely reversed; just as the world which is transformed was not in the least different, except in being turned.
