Heterodoxy as Compelling Analogy:

Samuel Gregg's article blasting liberation theology illustrates why heterodoxy will always make for a compelling analogy.

He writes:

As time passes, liberation theology is well on its way to being consigned to the long list of Christian heterodoxies, ranging from Arianism to Hans-Küngism. But as Benedict XVI understands, ideas matter – including incoherent and destructive ideas such as liberation theology. Until the Catholic Church addresses the legacy of this defunct ideology – to give liberation theology its proper designation – its ability to speak to the Latin America of the future will be greatly impaired. [Bold mine.]

I am not pro-liberation theology (I am a pretty doctrinaire capitalist.) However, were I, and I saw that comparison to the Arian heresy, I could respond, "you mean liberation theology is as bad as the Christianity that Milton, Newton, Locke, Clarke, Price, Mayhew and many of America's Founding Fathers believed in"? All of the aforementioned names either were or likely were Arians.
