What does the Bible say about oneness in Christ?

The Scriptures affirm that believers in Christ are one body, emphasizing unity despite individual differences. Romans 12:5 states, 'So we, being many, are one body in Christ, and every one members one of another.' Similarly, 1 Corinthians 12:12 illustrates this with the metaphor of the human body, indicating that various members serve different functions but are integral to the whole body. This oneness is established by Christ's redemptive work, not by our personal attributes or conduct.
