**1. Introduction**

In the period now being called the Anthropocene, the fatal vulnerabilities of the modern way of constructing selfhood are becoming ever more evident. Joanna Macy, who writes from a Buddhist perspective, has argued eloquently for the need to "green" the self by rediscovering its participation in ecological and cosmic networks. (Macy 2007, chp. 14) From a Christian perspective, this can be articulated in terms of an imperative to rediscover our spiritual personhood as radical communion in the God who creates and participates in the entire cosmos. The proposed path to this renewal is to give ourselves over into the rhythms of the Spirit, being breathed *in* to selfless communion in divine personhood and *out* to co-creation of our refreshed selfhood. (Frohlich 2019)

After this Introduction (Section 1), the three main parts of this essay will be: Section 2, an exploration of how the psychological process of "selfing" has changed in the postmodern era; Section 3, an account of some ancient and contemporary developments in the Christian understanding of "personhood"; and Section 4, presentation of a perspective on the rhythms of the Spirit as offering hope for the greening of the self and the sustainability of the planet.
