It's written in response to the (in)famous Letter to a CES Director, and I think the author (Adam S. Miller, who I've referenced often on this blog) hits the nail on the head.

If we look for Mormonism we will not find it; if we look to the grace that Mormonism aims us to, we will find both grace and Mormonism to boot.
