perichoresis: circuition, going around, or more precisely envelopment -- being drawn into the circulation of divine love and participating in the coinherence of the Divine Persons.
John 17:20-23.26: "I pray not only for them, but also for those who will believe in me through their word, so that they may all be one, as you, Father, are in me and I in you, that they also may be in us, that the world may believe that you sent me. And I have given them the glory you gave me, so that they may be one, as we are one, I in them and you in me, that they may be brought to perfection as one, that the world may know that you sent me, and that you loved them even as you loved me... that the love with which you loved me may be in them and I in them."
St. Alexander of Alexandria
"They hanged upon a tree Him Who stretches out the earth; they transfixed Him with nails Who laid firm the foundation of the world; they circumscribed Him Who circumscribed the heavens; they bound Him Who frees sinners."
