Hm. I didn't see the full context.

If by mythical you mean he is full of wonder and mystery, captivates the imagination and provides explanations for the unexplained, then sure, he is "myth became fact" as Lewis (and Vos) talked about. He was crucified "under Pontius Pilate," in a specific time and place. That's just historical fact.

But if you mean mythical in the more simplistic sense of being fictional, then that's inane.

Jesus came not to abolish the law but to fulfill it. The law (i.e. 10 Commandments) presupposes private property at every point -- which is the basis of what we call free market capitalism. Charity is also a moral (not political) command that rules out involuntary collectivism (taxation / forced income redistribution) by definition.

Anyone who thinks Jesus can be marshaled for their collectivist cause is ignoring the clear teaching of Scripture and making another god in their own image.
