Commentaries
17:20-23 Our Lord especially prayed, that all believers might be as one body under one head, animated by one soul, by their union with Christ and the Father in him, through the Holy Spirit dwelling in them. The more they dispute about lesser things, the more they throw doubts upon Christianity. Let us endeavour to keep the unity of the Spirit in the bond of peace, praying that all believers may be more and more united in one mind and one judgment. Thus shall we convince the world of the truth and excellence of our religion, and find more sweet communion with God and his saints.
20-23. Neither pray I for these alone—This very important explanation, uttered in condescension to the hearers and readers of this prayer in all time, is meant not merely of what follows, but of the whole prayer.
them also which shall believe—The majority of the best manuscripts read "which believe," all future time being viewed as present, while the present is viewed as past and gone.
