“Your mother died to save you. If there is one thing Voldemort cannot understand, it is love. He didn't realize that love as powerful as your mother's for you leaves its own mark. Not a scar, no visible sign… to have been loved so deeply, even though the person who loved us is gone, will give us some protection forever. It is in your very own skin. Quirrel, full of hatred, greed, and ambition, sharing his soul with Voldemort, could not touch you for this reason. It was agony to touch a person marked by something so good.”
“He didn't realize that love as powerful as your mother's for you leaves its own mark.”
“If there is one thing Voldemort cannot understand, it is love.”
“That which Voldemort does not value, he takes no trouble to comprehend. Of house-elves and children’s tales, of love, loyalty, and innocence, Voldemort knows and understands nothing. Nothing. That they all have a power beyond his own, a power beyond the reach of any magic, is a truth he has never grasped.”
“And his knowledge remained woefully incomplete, Harry! That which Voldemort does not value, he takes no trouble to comprehend. Of house-elves and children's tales, of love, loyalty, and innocence, Voldemort knows and understands nothing. Nothing. That they all have a power beyond his own, a power beyond the reach of any magic, is a truth he has never grasped...”
“You do not seek to kill me, Dumbledore?' called Voldemort, his scarlet eyes narrowed over the top of the shield. 'Above such brutality, are you?''We both know that there are other ways of destroying a man, Tom,' Dumbledore said calmly, continuing to walk towards Voldemort as though he had not a fear in the world, as though nothing had happened to interrupt his stroll up the hall. “Merely taking your life would not satisfy me, I admit —''There is nothing worse than death, Dumbledore!' snarled Voldemort.'You are quite wrong,' said Dumbledore, still closing in upon Voldemort and speaking as lightly as though they were discussing the matter over drinks. 'Indeed, your failure to understand that there are things much worse than death has always been your greatest weakness'.”
“Lily and James only made you Secret-Keeper because I suggested it,” Black hissed, so venomously that Pettigrew took a step backward. “I thought it was the perfect plan... a bluff... Voldemort would be sure to come after me, would never dream they’d use a weak, talentless thing like you... It must have been the finest moment of your miserable life, telling Voldemort you could hand him the Potters.”
