I agree with Jor-el that the word "Christian" means something specific in belief, and that without a sin in Genesis as he refers to, you are not a Christian. You are trying to dilute meaning of the word.
I find it interesting that the evolution-believing writers who criticise Jor-el probably also argue that an animal "kind" is not specific enough in scientific circles as a "species."
In Islam faith some believers interpret meanings of verses differently, as in all religions. However, there are some fundamental beliefs that a Muslim must have to properly be called Muslim. If you do not believe Muhammad was a prophet, you are not a Muslim. It sounds like with your loose meanings that you could simultaneously be Christian and Muslim at the same time.
