Myth is a lie told to reveal a truth.
Deception is a truth told to conceal a lie.
I love Christianity as mythology, like St. George the dragon slayer, but not only the fanciful stories of the saints, but also the stories directly from the Bible.
When you drop the does-this-make-sense, does-this-contradict-anything, and is-killing-everyone-with-an-epic-flood-a-good-use-of-divine-power questioning attitude and just look at the stories themselves; the characters, their choices, their emotions, etc., often they speak to different aspects of our lives that we can relate to, even thousands of years later.
Perhaps that's why I still enjoy a good sermon. To me, a good sermon tells a good story, and provokes some self-reflection.
But one of my biggest gripes with Christianity is that it is not written like Mythology. Although there are mystics and progressive Christians which would like to suggest otherwise, the Gospels are written as though they are literal truth. Yet comparing one Gospel to another reveals them to be false, or, at the very least, not completely true.
And that's one of the big reasons why I have a gripe with Christianity. It is told as truth when it clearly is not. While I love the mythology, I despise the deception, because it is this deception of truth which emboldens people to act like the southern half of a north-bound horse towards their neighbors when they don't happen to believe the same things, and it is this deception which claims the lives and resources of the pious prematurely and disproportionately.
Keep the Myth. Keep the self-reflection and stories. But let's ditch the false truth.
...now that that's settled, how do we go about getting people to do that? ;-)
