I’m non dénominationel Christian and id be interested by any kind of christianity inspired works, be they catholic or protestant or whatever.
Same for all religions: buddhism, islam, anything religious.
If not religious but spiritual and exceptionnal like PKD’s gnosticism, Im also curious. Not only for the gnosticism, but the whole doubting if some things experienced during psychosis are not all batshit-land, so I’ve also put Jung in my to read list, but let’s keep it sci-fi.


I’m not 100% sure, but you could try Brandon Sanderson’s “Skyward” and other books/stories in what’s apparently called “Cytoverse” series. I didn’t read them yet, that’s why no promises, but I’ve read his “Cosmere” books - those are not really sci-fi though, more fantasy/steampunk (depending on sub-series) - and I found a lot of Christian themes in there. To the extent that I sincerely found some to be helpful for my faith development (even if I’m of a different denomination). I wouldn’t be surprised if he put some such themes in his other books too.
As for CS Lewis, I had no idea he has any sci-fi books - I’ll have to find them now! He’s definitively a very Christian topics writer.
Will have a look TY.
Lewis 's space trilogy is a masterpiece.
