Community: beyond a western/pomo justification

now that title might sound a bit pretension, but here's the scoop. As many of you know i've been trying to read beyond my white evangelical theology which currently is leading me through Hispanic America theologians. and here is one of my observations.

To put it simply, for postmodern westerners longing for a return to community the prime source is the inner life of the Trinity. I.e. the foundation of community is from above, springing from the tri-personal life of the Trinity. (You can see this at perichoresis and a recent discussion led by Stanely Grenz which i was part of).

Now from the hispanic american perspective i've noticed that the foundation for community is not the Trinity, but rather Christology (the practices of Jesus which affirm universal humanity). This is community from below.

Now of course these aren't exclusive consideration or opposing perspective. But I do think it is interesting that white/pomo types look at the Trinity from the perspective of how it might inform their interpersonal/spiritual relationships, as means for moving beyond individualism, while the Hispanic thinkers look at the Trinity from the perspective of its socio-economic consequences (i.e how does power/love/sharing
relate).

so my question is, while trying to reclaim a communitarian theology through a retrieval of Trinitarian theology, are pomo westerners merely still perpetuating an apolitical "community" which continues to neglect the concerns of true community?
