And all mine are yours and yours are mine; and I am glorified in them.
All Commentaries on John 17:10 Go To John 17
Cyril of Alexandria
AD 444
Those then who have been given to Christ are the Father's, but are not therefore removed from Christ. For God the Father reigneth with Him, and through Him ruleth over His own. For the Holy and Consubstantial Trinity share the same kingdom, and their universal dominion is one and the same; and whatever is the Son's will be subject to the glory of the Son and the Father; and also, whatever is said to be under the rule of the Father, over that the Son will surely hold sway. And therefore He saith: And all Mine are Thine, and Thine are Mine. For as in Them perfect identity of Nature is visible and evident, the opinion held about Their majesty is not various, and does not attribute anything individually to One apart from the Other, but considers one and the same glory, identical in every respect, to attach to Both. For He That is by right of His Nature the Heir of His Father's Divine dignities will clearly have all that the Father hath, and will also show that His Father hath all that He Himself hath. For Either naturally reveals the Other in Himself; and the Son is seen in the Father, and the Father also in the Son. This kind of instruction the inspired writings gave us in the mystery. When, then, universal dominion is one of the dignities of the Father, it will belong also to the Son; for He is the express Image of His Person, and can endure no shadow of unlikeness or variance at all. He declares that He has been glorified in them, showing that His prayer for them is, as it were, a recompence well deserved.
