so if I own an animal I can torture it and that would be moral in your eyes?
The issue of slavery, man stealing i.e. slave trading, servitude, voluntary or involuntary, in both the ancient world and modern, by it's very nature excludes it from being able to be fully appreciated in one or two posts.
Whole volumes and literally thousands of articles, essays, books and other types of literature have been written by theologians and secular authors and researchers about this eclectic and multi-faceted issue.
The little known fact that North Carolina (the state in which I reside) is number 10 in America on the list of states where sex-traffiking (which is a form of slavery) is a booming mulit-million dollar underground industry is evidence that this issue is far more wide spread and complex than what is generally believed.
One simply cannot make accurate statements about slavery in the Bible without taking into account every aspect related to this issue. The following is a list off of the top of my head of these aspects:
1. The nature of ancient civilizations and or societies specifically regarding their economic infrastructure.
2. The nature of ancient civilizations and or societies and how they related to one another i.e in matters of war, in matters of forming alliances to build city-states etc. etc.
3. The nature of ancient civilizations and or societies and their view on what it meant to be a human being.
4. The nature of ancient civilizations and or societies on how they defended themselves from foreign invaders and how they positively sought to strengthen their territioral claims by invading other lands.
5. The nature of ancient civilizations and or societies and the laws they proscribed to be adhered to and the penalties and reprocussions of violating said laws with regards to the institution of indentured servitude.
6. The nature of ancient civilizations and or societies and how they viewed the most basic group within their society i.e. the family.
All of these and many more aspects must be thouroughly understood within their context of time, location, and to whom these aspects would be applicable to if we desire to be qualified in making assertions about slavery and it's morality or immorality as it relates to it's existence in Biblical times.
