Further Thought: Ellen G. White, “The Spirit of Unity”, pages 179-188, in Testimonies for the Church, vol. 9.
“Christ recognized no distinction of nationality or rank or creed. The scribes and Pharisees desired to make a local and a national benefit of all the gifts of heaven and to exclude the rest of God’s family in the world. But Christ came to break down every wall of partition. He came to show that His gift of mercy and love is as unconfined as the air, the light, or the showers of rain that refresh the earth.
The life of Christ established a religion in which there is no caste, a religion by which Jew and Gentile, free and bond, are linked in a common brotherhood, equal before God. No question of policy influenced His movements. He made no difference between neighbors and strangers, friends and enemies. That which appealed to His heart was a soul thirsting for the waters of life.” – Ellen G. White, Testimonies for the Church, vol. 9, pages 190, 191.
Summary: In his Epistle to the Ephesians, Paul gives many counsels regarding what it means for Christians to be “in Christ.” Salvation in Jesus transforms our lives in practical ways. All our human relationships, including relations between brothers and sisters in the church, are transformed by the power of Christ in our lives. And this transformation is crucial in order for us to have unity.
