Unity

D. A. Carson, commenting on Jn. 17:
“Although the unity envisaged in this capter is not institutional, this purpose clause at the end of v. 21 shows beyond possibility of doubt that the unity is meant to be observable. It is not achieved by hunting enthusiastically for the lowest common theological denominator, but by common adherence to the apostolic gospel, by love that is joyfully self-sacrificing, by undaunted commitment to the shared goals of the mission with which Jesus’ followers have been charged, by self-conscious dependence on God himself for life and fruitfulness.”
