Bede the Venerable
Catena Aurea · Johannesevangelium 17
Joh 17, Verses 24–26English original
Father, I will that they also, whom thou hast given me, be with me where I am; that they may behold my glory, which thou hast given me: for thou lovedst me before the foundation of the world. O righteous Father, the world hath not known thee: but I have known thee, and these have known that thou hast sent me. And I have declared unto them thy name, and will declare it: that the love wherewith thou hast loved me may be in them, and I in them.
That which He calls glory then is the love wherewith He was loved with the Father before the foundation of the world. And in that glory He loved us too before the foundation of the world.
