how does this idea of 'oneness' relate to old testament calls for justice for the marginalized?

Adds the setting and its conversation across both testaments.

Philippians 2:1-4

“If there is therefore any exhortation in Christ, if any consolation of love, if any fellowship of the Spirit, if any tenderness and compassion, make my joy complete, by being of the same mind, having the same love, being in full accord and of one mind; doing nothing through rivalry or through conceit, but in humility, each counting others better than himself; each of you not just looking to his own things, but each of you also to the things of others.”

Paul wrote this letter to the church in Philippi, likely from prison, sometime in the mid-1st century CE. He's encouraging them to live out their faith in unity, reminding them of the example of Christ's humility.

What practical steps can foster a sense of 'one mind' in a group or community without stifling individual differences?

Then — the setting

Paul wrote to the Philippian church around 60-62 CE, likely from Rome or Ephesus, while under house arrest. Philippi was a Roman colony, and its citizens were proud of their Roman status. This context might have contributed to internal divisions, as Roman society often valued status and hierarchy. Paul's emphasis on humility and unity would have directly challenged the prevailing cultural norms that encouraged competition and self-promotion.

Across the Testaments

This New Testament passage calls for unity and mutual consideration within the Christian community. In the Old Testament, the concept of 'oneness' is often expressed through the idea of Israel as a covenant people, bound together by their relationship with God and with each other. Calls for justice for the marginalized (e.g., widows, orphans, resident aliens) are central to this Old Testament covenantal unity, as the well-being of the most vulnerable reflects the health and faithfulness of the entire community. The New Testament expands this, grounding unity not just in a shared covenant with God but in the shared experience of Christ's self-emptying love, which then fuels the practical care for others, especially those in need.
