Hastings' Dictionary of the Bible (1898)
UNITY OF THE SPIRIT is unity of judgment, affection, and feeling among those who constitute the one body of Christ, Eph 4:3, and it is the gift of God. Jer 32:39. It was remarkably enjoyed in the early ages of the Church, John 17:21; Acts 4:32. and is to be sought after as among the chief of Christian graces. 2 Cor 13:11.
