In LDS theology, we talk about “redeeming the dead.” I think at least a portion of this means that we undo their errors and create a better world on the foundation–but also the ruins–of what they’ve left to us. Sometimes, we simply rearrange the ruins like a puzzle which makes a different kind of sense in a different kind of world. They bequeath both a legacy and a burden–and we are called to responsibility.
I love this perspective on redeeming the dead, and I pray that my own descendants will redeem me in exactly this manner. To do so, they will have to see me as redeemable, even if some of my beliefs seem ignorant (or even abominable) in the lens of 20/20 hindsight 150 years later. I pray they use that hindsight charitably and realize I was doing the best I could with what I know, just as they will be doing as they look back at me and forward to the judgment of their own descendants.
