So a bit of random (extremely niche) topic I recently delved into. The pre-existence of human souls is an idea officially condemned in the canonical tradition of the Church both East and West:
https://silouanthompson.net/2019/09/anathemas-against-origen/
But the very same idea appears to be affirmed in the rabbinical traditions of the Midrash and Talmud:
https://prophetictelegraph.co.uk/chapter-20-ancient-jewish-beliefs/
https://www.sefaria.org/Chagigah.12b.15?lang=en
https://www.myjewishlearning.com/article/body-soul/
https://www.jewishencyclopedia.com/articles/12340-preexistence-of-the-soul
These appear at first glance to be irreconcilable. But the seventh century Church Father Maximus the Confessor might offer a key to harmonizing them. He distinguishes between the literal human soul and a “logos” of a person that pre-exists in the mind and foreknowledge of God:
It should be pointed out that having an “existence” in the mind of God is something far and above having an “existence” in the mind of a human being, in the pages of a book, or in the databanks of a computer. This could theoretically allow for phenomena such as children reported memories of being in heaven waiting to be born (believe it or not, this is an actual thing: https://www.bethimmanuel.org/audio/anatomy-soul-kids-say-darndest-things ) It therefore suggests that rabbinical discourse on the topic actually speaks in a broad sense that tends to conflate the human soul itself with the logos from which it was created. This appears to be corroborated by the medieval Jewish philosopher Moses Maimonides:

It's also worth point out that Midrashim in particular are written in highly metaphorical and symbolic language that is not meant to be taken in a strictly literal sense:

I’m highly suspecting that Christian and Jewish discourse on this particular topic actually uses two different languages to describe the same thing…
