I think this chapter explained something which has struck me as strange for a long time:

If the killing curse can be stopped by love, how come only Harry ever survived? Its not like Lilly is the only person who ever loved anyone, nor the only person who would sacrifice themselves to save another.

Maybe the Potters possessed a new, experimental deathly hallow, one capable of stopping the killing curse (or, alternativly, an old one whoes purpose has been forgotton). It must have limits on its power, otherwise James and Lilly would have lived, and probably wouldn't have been tested thoroughly, otherwise Lilly wouldn't have seemed to panic so much (unless she was acting to stop Voldemort guessing).

This could be the stone which glowed, and it may or may not require a love/sacrafice to power it.

I thought about this for a while too, more than five whole minutes by the clock, and eventually I came up with a possible explanation.

It's not that Lily sacrificed herself for her child. As you and uncountable other people pointed out, that must have happened innumerable times throughout history, even just among the witches and wizards. It's that she sacrificed herself for her child when she could have lived.

Think of the oddness of the situation. The murderer arrives to kill the child, but not the mother. How often is that the case, historically? Then the murderer offers the mother a chance to live when she gets in his way, which is still stranger. When she rejects the offer to try to save her child, he does not bother to subdue her, but then chooses to kill her, which invalidates basically all of the explanations that I could think of that fit the above two criteria.

It's not that she sacrificed herself for her child--it's that the killer came with the express purpose of killing the child but sparing the mother, and she deliberately threw away that chance for her child. It never would have worked if he had come with the intent to kill her as well.

Which implies that Snape's request was what was needed to give Lily that opening. Which further implies that Snape really did save Wizarding Britain, if accidentally.

I don't believe I've shared the theory here before, I look forward to seeing if there are holes in the story that I have not yet discovered.
