The state of society was left to Caesar; the state of your soul was in your hands alone.
As postmodernism has eroded the concept of personal sin and hence guilt - (by arguing that morality is culturally relative and not universal, and that traditional social mores were repressive and needed to be overthrown) - they were replaced by collective guilt: society was guilty of certain "sins"; therefore society had to be changed "for the better"; hence the core moral argument for progressivism".
Liberalism in general- and its bastard sons progressivism and leftism - solve the problem of collective guilt. Individuals don't have to behave in a traditionally upright moral manner as long as they support to collective's agenda to rids society as a whole of its sins.
These sins are racism, sexism, colonialism, capitalism, and traditional Judeo-Christianity.
Today, one can personally be guilty of any traditional sin, and even be guilty of personally transgressing a collective sin, but be absolved of these sins if one also supports the liberal agenda.
And the agenda doesn't even have to be effective at changing society for the better for it to be able to assuage the guilt of the liberal who transgresses.
This is how limousine liberals who jet around all the time and own huge homes and rent ginormous yachts and otherwise have enormous carbon footprints still see themselves - and are seen by other liberals - as climate crusaders.
This is how they can support and want to mainstream all sorts of salacious libertinage that have been seen as anarchistic by most cultures fr mist of human history.
This is the basis of liberation theology - a religion that puts the emphasis on the collective.
This is why liberals have blamed society for the cries criminals choose to commit.
This is what motivates liberals to want to take over healthcare, energy, CO2, H2O, and regulate all commerce and trade: they see the side-effects of fluid social systems operating as marketplaces creating winners and losers and instead of assigning blame to the individuals, they blame society and therefore argue only a collective overhaul commanded from on high can fix things, ("things" being what individuals do on their own in their own interest).
The goal of the liberal is not personal salvation; it is utopia... a sort of collective heaven here on Earth.
History has shown that these liberal collective policies inevitably create a hell on Earth.
So, why do liberals persist in advocating them?
They persist because it makes them feel good about themselves - regardless of what they do personally to positively effect the problems they see and regardless of how abominably they behave in their private lives.
I think Bill and Hillary Clinton epitomize this at the current time.
Liars, cheaters, thieves who see themselves and are seen by many liberals as great people.
But truly evil.
One of the few truly collective responsibilities we have as a nation is national defense: individually we cannot defend our nation from external threats.
And it is no coincidence that liberals always attack this common cause.
Anything that perpetuates our nation also perpetuates the West and Judeo-Christian Civilization.
And a cornerstone of this civilization - and the system of government it gave rise to after thousands of years of struggle, self government - is individualism.
And nothing is more threatening to a collective hell-bent on creating a utopia on Earth than the individual who wants to live his own life in accordance with eternal, traditional and times-tested values.
Salvation is personal.
Unless you are a liberal.
Obama knows this and has spoken about it:
This is why fighting liberalism is not just a fight for our nation, for the West and the Free World or Judeo-Civilization; it is a fight for you soul.
If you give into the left, then you have surrendered your own soul.
