2. The shalom of the persons is the eschatological shalom of the people of God, which we are called to and long for, which we await with all creation, and to which we summon our neighbors. [Explain]
2a. Love requires a lover and a beloved and the love itself. When we, following scripture, assert "God is love," we confess that God is a plurality in unity; God is love.
2b. The life of the church--in all its varied practices--tells and participates in the Father's sending of the Son and the Spirit for the sake of the world. The church community is the imago Dei and its spirituality is no exercise in individualism since God is a fellowship, not a monad.
2c. To state in another way: the Great Commission is a repetition of the sending of the Son, which is itself a reflection of the eternal begetting of the Son in history. But this time, the church is invited.
3. The people of God whose head is Jesus of Nazareth are invited to participate by grace in the loving oneness of the persons. By grace, not by nature. The flesh of Jesus is forever scarred. This is the doctrine of theosis, the foundation of Christian anthropology. In the words of the early church fathers: He became like us so that we can become like him.
4. Christian spirituality is inside out: an always moving current into God and into the community. There is a holy and joyful eros to it as we, through the Son and by the Spirit, are caught up into the perichoretic dance to the Father.
4a. Christian spirituality is triune from the foundations.
5. The Doctrine of the Trinity, revealed just in the light of awareness as we became no longer servants but friends, is a summing up of the whole. And, together with the two-natures of the Son, tells the whole thing in a glance.
6. Afterthought: Do not get overcome by how are there three in one. Sometimes you emphasize the oneness; sometimes the threeness. Heresy cannot be avoided. So, sin boldly!
