Patristic Wisdom: Looking to the Seventh Sunday of Easter

Holy Father, keep through Your name those whom You have given Me, that they may be one as We are. While I was with them in the world, I kept them in Your name. Those whom You gave Me I have kept; and none of them is lost except the son of perdition, that the Scripture might be fulfilled. But now I come to You, and these things I speak in the world, that they may have My joy fulfilled in themselves. I have given them Your word; and the world has hated them because they are not of the world, just as I am not of the world. I do not pray that You should take them out of the world, but that You should keep them from the evil one. They are not of the world, just as I am not of the world. Sanctify them by Your truth. Your word is truth. As You sent Me into the world, I also have sent them into the world. And for their sakes I sanctify Myself, that they also may be sanctified by the truth. (John 17:11b-19)

Christ wishes the disciples to be kept in a state of unity by maintaining a like-mindedness and an identity of will, being mingled together as it were in soul and spirit and in the law of peace and love for one another. He wishes them to be bound together tightly with an unbreakable bond of love, that they may advance to such a degree of unity that their freely chosen association might even become an image of the natural unity that is conceived to exist between the Father and the Son. That is to say, he wishes them to enjoy a unity that is inseparable and indestructible, which may not be enticed away into a dissimilarity of wills by anything at all that exists in the world or any pursuit of pleasure, but rather reserves the power of love in the unity of devotion and holiness. And this is what happened. For as we read in the Acts of the Apostles, “the company of those who believed were of one heart and soul,” that is, in the unity of the Spirit. This is also what Paul himself meant when he said “one body and one Spirit.” “We who are many are one body in Christ for we all partake of the one bread,” and we have all been anointed in the one Spirit, the Spirit of Christ.

Cyril of Alexandria, Commentary on the Gospel of John 11.9
