First, you have to look at our way of thinking compared to those in biblical times...They did not see it as morally wrong at all...Thus every nation had slaves...They did not think like we do now AT ALL...Intellectualism has given rise to debate over whether slavery should be considered moral and outlawed...A HUGE portion of this debate has to do with our constitution and interpreting the law which states all men are created equal...You see, it wasn't based on the Bible that Christians decided slavery was not moral, it was based on our constitution...Christ also taught to submit yourselves to those in power and to the laws which are in place...At the time, no laws were established condemning slavery no matter how bad you thought it was...In recent times we HAVE established laws stating that slavery is outlawed and thus as Christians we must follow the laws of our land...
