As a behavioral/social scientist I decided the words attributed to Jesus, "love your neighbor as yourself" (a.k.a. the golden rule) is the salvation of human society. Not because it came from "god", but because it was figured out by wise humans looking at the "big picture" long before Jesus time (if he existed). "Salvation" (maximising our existence) comes by taking care of (loving) ourselves, and doing what we can to help others do the same. Thinking about WE, not just ME. It is at the core of major world religions.
