21.

And for this reason also the words, ‘that they may be one in Us,’ have a right sense. If, for instance, it were possible for us to become as the Son in the Father, the words ought to run, ‘that they may be one in Thee,’ as the Son is in the Father; but, as it is, He has not said this; but by saying ‘in Us’ He has pointed out the distance and difference; that He indeed is alone in the Father alone, as Only Word and Wisdom; but we in the Son, and through Him in the Father. And thus speaking, He meant this only, ‘By Our unity may they also be so one with each other, as We are one in nature and truth; for otherwise they could not be one, except by learning unity in Us.’ And that ‘in Us’ has this signification, we may learn from Paul, who says, ‘These things I have in a figure transferred to myself and to Apollos, that ye may learn in us not to be puffed up above that is written ¹.’ The words ‘in Us’ then, are not ‘in the Father,’ as the Son is in Him; but imply an example and image, instead of saying, ‘Let them learn of Us.’ For as Paul to the Corinthians, so is the oneness of the Son and the Father a pattern and lesson to all, by which they may learn, looking to that natural unity of the Father and the Son, how they themselves ought to be one in spirit towards each other. Or if it needs to account for the phrase otherwise, the words ‘in Us’ may mean the same as saying, that in the power of the Father and the Son they may be one, speaking the same things ²; for without God this is impossible. And this mode of speech also we may find in the divine writings, as ‘In God will we do great acts;’ and ‘In God I shall leap over the wall ³;’ and ‘In Thee will we tread down our enemies ⁴.’ Therefore it is plain, that in the Name of Father and Son we shall be able, becoming one, to hold firm the bond of charity. For, dwelling still on the same thought, the Lord says, ‘And the glory which Thou gavest Me, I have given to them, that they may be one as We are one.’ Suitably has He here too said, not, ‘that they may be in Thee as I am,’ but ‘as We are;’ now he who says ‘as’ ⁵, signifies not identity, but an image and example of the matter in hand.
