Disagree. His ideas may have been radical to the establishment, but the Master was the ultimate in conservative. To realize this, you must consider His ultimate goal: that of reconciling man to God. Basically, a return to a singular principle of denying self in favor of God.
Liberalism is the polar opposite.
Liberalism is quintessentially “worldliness”, being a friend of the world (and the father of this world - Satan).
James 4:4
Adulterers and adulteresses! Do you not know that friendship with the world is enmity with God? Whoever therefore wants to be a friend of the world makes himself an enemy of God.
But since Jesus is the antithesis of Evil, he cannot be a Liberal (in the Democrat Party sense). Liberals require a compromise with, or outright submission to Evil, and I don't remember Jesus being big on the whole “compromising beliefs” thingy.
Yes, radical, and also very liberal in contrast to the establishment.
His ultimate goal: that of reconciling man to God.
Agreed, and he'd probably be shocked at a good portion of organized Christianity today.
