Christianity is agreed to be indifferent to matters of slavery; which is also compatible with the Ancient Greek thought. The following quotations from the different parts of The New Testament show that slavery is not considered a big social problem in the eyes of Christianity. Moreover, Christianity advises slaves to be obedient to their masters, regardless of whether they are good or evil: However, there are also verses that refer to the equality and unity of all human beings-around the personality of Jesus Christ, which leads us to thinking that the social order making room for slavery is only a worldly illusion. On the basis of these quotations from the primary source of Christianity, it is possible to argue that even religions-including the monotheistic were inadequate in changing the socio-economic circumstances of the time they emerged. So, even the apostles of Jesus Christ did not have enough courage and confidence to forbid and/or to stand against slavery although Christianity is quite often advertised as “the religion of free will/freedom”.
