Well, that's it in the Greek...Should we check the English to see if we get a connotation that's acceptable to you???
You are telling us words. I am quite good with Greek myself, but thanks.
Both "flesh" and "corruption" are used by the inspired authors primarily as references to the temptation, sin, and death as consequence of sin. None of your quotes are a physiology manual from which we are to deduce the fact that ordinarily, people experience physical death and their flesh decays. Nor does any Catholic dispute these facts of life.
Go troll someplace else.
