History of the term 
Stewardship originally comprised the tasks of a domestic steward. Stewardship initially referred to the household servant’s duties for bringing food and drink to the castle’s dining hall. Stewardship responsibilities were eventually expanded to encompass the domestic, service and management needs of the entire household. Commercial stewardship tends to the domestic and service requirements of passengers on ships, trains, airplanes or guests in restaurants. This concept of stewardship continues to be referenced within these specific categories. Stewardship is now generally recognized as the acceptance or assignment of responsibility to shepherd and safeguard the valuables of others.
