It seems that the doctrine of the Trinity keeps popping up in my life. After a horrible chapter on theology and culture, Grenz and Franke move Beyond Foundationalism’s discussion toward the concept of the Trinity. They acknowledge the controversy and disillusionment the term brings to mind for many people, and I concur that it has come, for many people,
to be regarded as little more than an abstract and indefensible example of the excesses of speculative theology…Colin Gunton summarizes well this aspect of the contemporary theological climate: “Overall, there is a suspiction that the whole thing is a bore, a matter of mathematical conundrums and illogical attempts to square the circle.”…Many…are convinced that giving [the doctrine of the Trinity] a place in the theological enterprise…is to invite worthless, even detrimental speculation. p170-171
Already this chapter has my blood pumping. Here’s what I’m bringing into it:
-I’m tired of rationalist formulations that demand total by-faith acceptance of propositions about God that aren’t found in the Bible (such as, “The Father and Son are coequal,” whatever that means)
-I fully agree with the Trinitarian nature of “Father, Son, and Spirit” terminology, because it is quite biblical and doesn’t requre mental gymnastics nor eliminate mystery entirely. Robert Webber’s latest newsletter featured this prayer:
Lord God, creator of heaven and earth.
Lord Jesus Christ, redeemer of all things visible and invisible.
Holy Spirit, who quickens the new life within.
May your transcendent presence dwell in this community this hour,
Guiding our thoughts and conversation.
To the glory of your Holy Name.
Amen.
Grenz and Franke also refer to these roles for each Person - “The Father and creation; the Son and reconciliation; the Spirit and salvation as well as consummation” (p170). I like Webber’s description best, because he refers to the Spirit in regards to resurrection, which I think is central. I’m not sure exactly where Grenz and Franke are going with the “Spirit and consummation” angle yet.
The Holy Spirit’s role in giving new life - resurrection life - is inherently eschatological, because the “new heavens and new earth” are in a sense a resurrection, just as Jesus’ body was a resurrection body - contiguous with the old, yet transformed powerfully. We long for the same kind of resurrection, to be truly ourselves, yet to be transformed into what we were always meant to be, and to be with God forever.
