As ever, absolute moral authority only belongs to those who preach civility and compassion for others -- while ramming their own policy preferences and values down our throats.
She makes a valid point point. Once we divorce ourself from the Creator, there is no transcendent anchor and moral truth becomes subject to our capricious, changing whims; it literally becomes whatever we fancy. Of course this tendency is not restricted to progressive leftists. It originated long ago with the rebellion of Satan when he decided to appropriate for himself that which is the purview of God alone. This lie was then propagated into Eden with catastrophic results for mankind. From there it spread over the whole Earth. A moral cancer, it infects entire cultures and governments. Indeed, everyone without exception is born with this tendency. Left unchecked, this moral relativism always leads to misery and ruin ... and ultimately destruction.
There is a deadly link between moral relativism and the theory of evolution - i.e., since humanity evolved from lesser to greater biological organisms, the same process must be in play for moral truth. In other words, there can be no absolute or fixed moral truth which must always be constantly "evolving" to accommodate changing circumstances and desires. Paul Kurtz, in the book "The Humanist Alternative", sums up the logical conclusion: “If man is a product of evolution, one species among others, in a universe without purpose, then man’s option is to live for himself”. It's the age old lie from Eden.
For some time now, I've believed the moral argument is the strongest philosophical argument for the necessary existence of God. God’s image is impressed upon humanity (cf. Gen. 1:26-27) so that human beings instinctively know God’s moral law and what is right and wrong (cf. Rom. 2:14-15). People don’t have to believe in God to know His moral law; but in denying Him, we lose the critical ability to ground objective moral truth in an anchor than transcends the physical universe. Without a transcendent God, as Dostoevsky famously observed, everything becomes permissible.
If there is absolute truth, then there are absolute standards of right and wrong and we are accountable to those standards. This accountability is what people are really rejecting when they reject absolute truth. The rejection of absolute moral truth is ultimately the fatal rejection of reality. Every historical civilization, without exception, eventually disintegrated because of this. We are now witness to the tragic death throes of our own culture arrogantly led by deluded politicians, a media propaganda machine, agenda-driven public education, and pompous "entertainment" - as it arrogantly assumes absolute moral authority and collectively descends into madness.
There is a sobering warning for Christians who may be caught up in this powerful delusion and embrace manufactured truth ........
“Go out of the midst of her, my people! Let every one save his life from the fierce anger of the LORD! (Jer 51:45, ESV)
Then I heard another voice from heaven saying, “Come out of her, my people, lest you take part in her sins, lest you share in her plagues (Rev 18:4, ESV)
