Waton, glad you're not having bed room issues. You can be certain the meaning the author intended is 'corrupted'.
raymond franz....No. Your logic is flawed. Notice 19:2 used the same word gēn when condemning Rome's corruption/ruining of the earth. Further, your parsing of definitions between oikoumeni (3625) and gen are overly literal and limiting. Oikoumeni simply means land that is inhabited. It does not mean the people apart from the land. Gen and oikoumeni are interchangeable in most contexts. Go consult with your Greek professor. Better yet get yourself a good novel and step away from the apocalypse stuff for a while.
