Put to death, therefore, whatever in you is earthly: fornication, impurity, passion, evil desire, and greed (which is idolatry). On account of these the wrath of God is coming on those who are disobedient. These are the ways you also once followed, when you were living that life. But now you must get rid of all such things—anger, wrath, malice, slander, and abusive language from your mouth. Do not lie to one another, seeing that you have stripped off the old self with its practices and have clothed yourselves with the new self, which is being renewed in knowledge according to the image of its creator. In that renewal there is no longer Greek and Jew, circumcised and uncircumcised, barbarian, Scythian, slave and free; but Christ is all and in all! As God’s chosen ones, holy and beloved, clothe yourselves with compassion, kindness, humility, meekness, and patience. Bear with one another and, if anyone has a complaint against another, forgive each other; just as the Lord has forgiven you, so you also must forgive. Above all, clothe yourselves with love, which binds everything together in perfect harmony. And let the peace of Christ rule in your hearts, to which indeed you were called in the one body. And be thankful. Let the word of Christ dwell in you richly; teach and admonish one another in all wisdom; and with gratitude in your hearts sing psalms, hymns, and spiritual songs to God. And whatever you do, in word or deed, do everything in the name of the Lord Jesus, giving thanks to God the Father through him. (Colossians 3:5-17, NRSV)
No matter what you were, once you have been brought into the body, you are one in the same with all other members of the body. And thus we should work together in harmony.
We need to have compassion, kindness, humility, meekness, and patience with all. And bear each other in love, because in Christ we are made one.
Christ is all in all and all of us are one in Him.
