Living Mythologically

To be truly comfortable as an OPer, I think you really have to be comfortable with mythology. I know some people who are totally like that, but they tend to be touchy feely types. Ex Chareidim or rationalist MO types have a much harder time of it. It's strange though, because as a RWMOer, I never had a problem saying Kiddush ( for example), and saying God created the world in 6 days and rested on the seventh, even though I knew that wasn't literally true. But saying Elokay avrohom while knowing that Breishis is legend is somehow harder. I guess it's whatever you are used to. Chareidim meanwhile freak out at the thought of an ancient earth, they can't imagine being able to say Kiddush without it being literally true. So what's the secret? How does one get comfortable with myth? It's not easy.
