Reason for converting Good Christians

[AtheistPhil]

3)AFAIK(I am not from the US), the people who liberated the blacks are Christians.

While nearly all Modern Christian religions condemn the practice of slavery, the Bible upon which they base their beliefs does not condemn slavery, and numerous passages in the Bible have been used in support the practice. This paradox requires some explaining.

In the early years of Christianity, slavery was a normal feature of the economy and society in the Roman Empire and well into the Middle Ages and beyond. Centuries later, as the abolition movement took shape across the globe, groups who advocated slavery's abolition attempted to harness Christian teachings in support of their positions. However, they were forced to refer to the 'spirit of Christianity' rather than quote the Bible. On the other hand, those opposed to abolition and equal rights were able to and did quote numerous Biblical passages that permit and regulate the practice of slavery.

Believing in the 'modern spirit of christianity' is OK, but believing in the Bible can justify a lot of monstruosity. That's why the strict belief in christianity and the Bible is potentially dangerous.
