'Difference' in the Bible

a renewal in which there is no [distinction between] Greek and Jew, circumcised and uncircumcised, [nor between nations whether] barbarian or Scythian, [nor in status whether] slave or free, but Christ is all, and in all [so believers are equal in Christ, without distinction].

bearing graciously with one another, and willingly forgiving each other if one has a cause for complaint against another; just as the Lord has forgiven you, so should you forgive.
