the sheerest of mortal pretense

Does "the sheerest of mortal pretense" mean "the deadliest hypocrisy"?

---------------------------
Liberals and moderates, on the other hand, refuse to draw any conclusions whatsoever about God from his works. God remains an absolute mystery, a mere source of consolation that is compatible with the most desolating evil. In the wake of the Asian tsunami, liberals and moderates admonished one another to look for God "not in the power that moved the wave, but in the human response to the wave." I think we can probably agree that it is human benevolence on display—not God's—whenever the bloated bodies of the dead are dragged from the sea. On a day when over one hundred thousand children were simultaneously torn from their mothers' arms and casually drowned, liberal theology must stand revealed for what it is: the sheerest of mortal pretenses. The theology of wrath has far more intellectual merit. If God exists and takes an interest in the affairs of human beings, his will is not inscrutable.
