This one just blows me away:

The couple:
- Travel overseas to raise funds for a hospital
- Spend 50 years in Africa helping those in poverty
- Build five schools and four hospitals
- Feed and clothe thousands
- Attribute their success to God
- Live their entire life by the Golden Rule
- Acknowledge their works are done for God
- Help people lead better lives
- Sacrifice everything to serve people in God's name
- Do everything they can to help poor people
- Trust that their good works will please God and get them into Heaven
The man:
- Kills another man in a drunken brawl
- Acknowledges that Jesus is his Saviour
God sends the couple to Hell and the man to Heaven solely based on their respective last points. How do people honestly accept that as the actions of a benevolent and just being?
The Reformation was an interesting memetic development. Previously, what caused people to flock to Christianity was their good works -- some of the earliest known references mention how they care for the old and sick with no concern for their own welfare.
But, once established, and, worse, having more or less "mandatory volunteerism" integrated (modern socialists, are you paying attention to history?) into the religion itself, it became a duty, and thus distasteful.
"Lead by example", the best possible way to sway people to your side, became "Do as I say", which, as we skeptics all know, totally sucks when you're trying to convince people of something. (Still paying attention?)
Keep your mouth closed, and do your thing, and people will see you as Win rather than Fail, and will look positively. They see Success, and have evolved to ape it, because it is Success and not death and misery and starvation.
Anyway, back to the memetic shift. So the "good works" have turned into a duty. A Christianity variant mutates, shucking it off, to be rid of the "do as I say" aspect.
"Surprisingly", it is popular.
The mutated meme did very well to reproduce from that point forward. It didn't kill off the outdated meme, which had begun to spread to different continents, but in Ye Olde Europa, it did just fine, especially in the north, further from the center of empire.
So here we are, hundreds of years later, with the meme having buffed and polished its rationalizations. It is doing what it is designed* to do: Spread, by inducing behaviors that engender its spread, independent of whether the meme is "true" or not.
* Oops, I violated skeptic rule number 3: Never say "designed" when talking about evolution.
