Friends, in today’s Gospel, Jesus declares, “The Father is in me and I am in the Father.”
Charles Williams stated that the master idea of Christianity is “coinherence,” mutual indwelling. If you want to see this idea concretely displayed, look to the pages of the Book of Kells, that masterpiece of early Christian illumination. Lines interwoven, designs turning in and around on each other, plays of plants, animals, planets, human beings, angels, and saints. The Germans call it Ineinander (one in the other).
How do we identify ourselves? Almost exclusively through the naming of relationships: we are sons, brothers, daughters, mothers, fathers, members of organizations, members of the Church, etc. We might want to be alone, but no one and nothing is finally an island. Coinherence is indeed the name of the game, at all levels of reality.
And God—the ultimate reality—is a family of coinherent relations, each marked by the capacity for self-emptying. Though Father and Son are really distinct, they are utterly implicated in each other by a mutual act of love.
The impossibly good news is that Jesus and the Father have invited us to enter fully into their divine coinherence. The love between the Father and the Son—which is called “the Holy Spirit”—can be participated in.
