OK, I'll bite.
St. John the Evangelist and author of the Gospel bearing his name is the beloved disciple. He is the beloved disciple because of his childlike faith in Jesus, because he followed his Lord through thick and thin, even to the foot of the cross, because he rested his head on Jesus's Chest, because he ate His Body and drank His Blood in the Eucharist, because he testified to Jesus even through torture and imprisonment, because he accepted Mary as his mother...
And any one of us who does the same is also Jesus's beloved disciple, who must take up his cross, follow Jesus to His Crucifixion, and consecrate himself to Our Blessed Lady and Mother.
