This adjective describes people who are like-minded or united in thought—literally 'same-minded' (ὁμός + φρήν). In 1 Peter 3:8, it heads a list of relational virtues: 'Finally, all of you, have unity of mind, sympathy, brotherly love, a tender heart, and a humble mind.' The term emphasizes intellectual and emotional alignment—shared perspective and mutual understanding within the Christian community. It's relational harmony rooted in common convictions and affections, essential for church unity.
