Galatians 3:28

There can be neither Jew nor Greek, there can be neither bond nor free, there can be no male and female; for ye are all one man in Christ Jesus. [Having declared that faith, that is to say, the gospel, brings us into sonship to God, Paul describes the particular step by which this is accomplished. That step is baptism, for by baptism we become part of the mystical body of Christ. We put on the personality of Christ in the sight of God, and so become, in an individual sense, sons of God, but the individual sense is almost wholly lost in the collective, so that all those racial distinctions and all the fictitious distinctions of caste, and even the distinction of gender, which made a man look upon a woman with contempt, are lost sight of. Not only are all men and women new creatures in Christ Jesus, so that old things are passed away, but they are all part of one new organism, which in glory and importance obscures all former differences.]
