I didn't know that the American Christian movie industry had the resources, time or know-how to make a knockoff of Finding Nemo. I guess it makes sense considering it's the religion of choice of the settler population there and is used as a cudgel to enforce "American values" or whatever.
Foundations of Christianity by Kautsky for example. It wasn't even an exclusive christian thing, christians took that from essenes for example, and many other isolated religious sects over the world were similar. Keyword here is "primitive" communism.
