Semper Gumby!
According to the venerable academic source of all things accurate, Semper Gumby is an unofficial motto for the United States 
Marine Corps, Navy fast attack submariners, Navy Seabees, USCG personnel, and the Civil Air Patrol. It is a play on the official motto Semper Fidelis, usually abbreviated Semper Fi, which means “Always Faithful”, and that of the US Coast Guard, Semper Paratus, meaning “Always Ready.” Semper Gumby, referring to the cartoon character Gumby, means “Always Flexible.”
Personally, I think it is the vital attitude for anybody that intends to survive the transition from more traditional church forms to the “hang on to your hat” world of the simple church. As far as that goes, it needs to be the attitude of anyone in the house church community.
