Liberty, the Family, and Morality

I recently read The Divine Institution of Marriage and one of the most insightful paragraphs reads as follows:

Finally, throughout history the family has served as an essential bulwark of individual liberty. The walls of a home provide a defense against detrimental social influences and the sometimes overreaching powers of government. In the absence of abuse or neglect, government does not have the right to intervene in the rearing and moral education of children in the home. Strong families are thus vital for political freedom. But when governments presume to redefine the nature of marriage, issuing regulations to ensure public acceptance of non-traditional unions, they have moved a step closer to intervening in the sacred sphere of domestic life. The consequences of crossing this line are many and unpredictable, but likely would include an increase in the power and reach of the state toward whatever ends it seeks to pursue.

I then recalled something that John Adams said regarding the necessity of morality to ensure liberty:

Statesmen, my dear Sir, may plan and speculate for liberty, but it is religion and morality alone, which can establish the principles upon which freedom can securely stand. The only foundation of a free Constitution is pure virtue, and if this cannot be inspired into our People in a greater Measure than they have it now, they may change their rulers and the forms of government, but they will not obtain a lasting liberty.

By supporting Proposition 8 we defend traditional marriage and morality, both of which are necessary to secure liberty.
