Therefore, the chosen People of God is one: "one Lord, one faith, one baptism"(Eph 4:5); sharing a common dignity as members from their regeneration in Christ, having the same filial grace and the same vocation to perfection; possessing in common one salvation, one hope and one undivided charity. There is, therefore, in Christ and in the Church no inequality on the basis of race or nationality, social condition or sex, because "there is neither Jew nor Greek: there is neither bond nor free: there is neither male nor female. For you are all 'one' in Christ Jesus."(Gal 3:28 ; cf Col 3:11)
If therefore in the Church everyone does not proceed by the same path, nevertheless all are called to sanctity and have received an equal privilege of faith through the justice of God (cf 2Pt 1:1). And if by the will of Christ some are made teachers, pastors and dispensers of mysteries on behalf of others, yet all share a true equality with regard to the dignity and to the activity common to all the faithful for the building up of the Body of Christ.
