No Jew or Greek? I believe that Paul never asked the different national groups to drop their culture and blend into some new nation called Christian. Jews were to remain Jews. Romans were still Romans. Ephesians were still Ephesians. Society was not suddenly chaotic. But Christ was in all the various ethnicities. They were equal. Americans are not asked to leave their nation and join another nation. Sin is everywhere. There is no chosen race somewhere. But Christ in that nation makes individuals different. American Christians love believers in India, but they are not therefore Indian. They are still American. But Christ in us gives us the ability to love those whose language and practices are different than ours. The nations stand, for now, but we will inherit the earth one day as simply Christ. Our oneness does not cancel our diversity. All tongues and nations, as those tongues and nations will praise Him forever. A symphonic blend, not the blend of a blender.

No slave or free? Remember that smallest portion of New Testament Scripture? Paul appeals to slave-owner Philemon to receive slave Onesimus back without punishing him. He even suggests that Onesimus is now his brother. But he does not suggest/demand that he should set him free! Functionally Onesimus and Philemon are still very different, but due to Christ's inheritance, they are going to the same Heaven. And in that land things are judged differently. But even there, they will have rewards that vary according to their works. Even in His Eternal Presence, there will be differences! So Master and Servant are equal in value, worth, future. But still they are the servant and the master. Today the Christian employer is not asked to step down and become one of the hired hands. The employee is not asked now to sit in the manager's office. But Christians recognize Christ in the different offices and functions of the company and walk accordingly. All the rules of the Kingdom apply to these two as well as all the ongoing rules of life here.

No male or female? Yet Paul gives advice to mothers and wives which men cannot follow. He speaks to husbands and fathers in ways that women simply must ignore. Male and female still exists, in our homes, and in the church. But in terms of our inheritance, our eternal salvation, our filling with the Spirit, our knowledge of the Word, our access to God through prayer, our call to love and bear all the fruit of the Spirit, we are one. God becomes gender-blind when looking at us in His eternal purposes.

We are one and equal in Christ. We are Abraham's seed. We are heirs by promise.

Paraphrasing John Piper and Wayne Grudem in their 50 Crucial Questions,

Galatians 3:28 does not abolish gender-based roles given by the same apostle elsewhere. This passage is not an authorization of homosexuality in the church, is it? If there is neither male or female in Christ, then we are free sexually to abandon traditional roles, right? No, Paul elsewhere condemns such behavior.

They also mention in this connection the Apostle Peter's converging text. Peter also says that we are joint heirs with Christ, equal in the promised inheritance (I Peter 1:3, 4). But 2 chapters later he talks of women, even women in Christ, being the "weaker" partner of a marriage relationship (3:7). He (2:13-3:7) and Paul (Ephesians 5:22-6:9) establish the traditional order of things both in the home and in the church , since these roles have not changed "in Christ" even though our heavenly status certainly has.
