The word 'liberal' has lost its original meaning and usage today. It's because of how Christ's enemies have slowly stained it to include ideas that allow the sinner to continue in sin and to hate the idea of a ruling class, and in general, the idea of 'authority'.
At one time it was a term associated with the ruling nobility who oversaw the health and care of their subjects living on the lands they were entrusted with by the royal monarch, while they recognized and subjected themselves to the divine authority of the ruling monarchy. (See Jane Eyre's Pride and Predjudice for an example of this, which is often protrayed negatively by liberals, especially in Hollywood. Whole volumes could be written of the positive associations the nobles and aristocracy had with the care and health of their subjects during those periods of western history, yet most of the history we are fed about that era leans towards the revolutionist's view).
With the French Revolution of the 1780's, which ended the reign of the French monarchy and noble ruling class, its changed meaning took off, with French Revolution phrases like 'Fraternity, Equality, Liberty, Brotherhood'. That's when ideas of revolution became strongly associated with ideas of Liberty and thus Liberalism.
Because of the French Revolution, some in England then coined the term 'conservative' to represent those who still supported the right of divine reign by the royal monarchy, along with its traditional institutions, which included The Church.
So the idea of a liberal used to mean one of noble character who dealt well with the care of those they were entrusted to rule over, but now has become a word associated with the negative thinking of overthrowing... rule and authority with the idea that we don't need any... ruling class over us. And the tenets of Communism adopted the French Revolution ideas of overthrow of divine monarchs, even with murdering the monarchs of Russia, the Czar Nicolas II and Alexandria in the October Revolutiion of 1917. The Marxist philosphy that produced Communism stated that eventually, Communist society would no longer have need of any... ruling class over the people.
When our Lord Jesus Christ returns, He's going to settle this matter, as He will be The Ruling Monarch KING over us ALL, and His princes will rule in judgment.
Isa 32:1-8
1 Behold, a king shall reign in righteousness, and princes shall rule in judgment.
2 And a man shall be as an hiding place from the wind, and a covert from the tempest; as rivers of water in a dry place, as the shadow of a great rock in a weary land.
3 And the eyes of them that see shall not be dim, and the ears of them that hear shall hearken.
4 The heart also of the rash shall understand knowledge, and the tongue of the stammerers shall be ready to speak plainly.
5 The vile person shall be no more called liberal, nor the churl said to be bountiful.
6 For the vile person will speak villany, and his heart will work iniquity, to practise hypocrisy, and to utter error against the LORD, to make empty the soul of the hungry, and he will cause the drink of the thirsty to fail.
7 The instruments also of the churl are evil: he deviseth wicked devices to destroy the poor with lying words, even when the needy speaketh right.
8 But the liberal deviseth liberal things; and by liberal things shall he stand.
(KJV)
