I have been gripped these past few years by the notion of a 'sacramental worldview' that sees a unvisible, universal, eternal truth expressed in visible, localized, time-bound shapes, so in something that is part of our world, we see what has always been true even if we didn't know it. The loss of this view and of the interwoven nature of Gods reality and ours, has led to us viewing creation as 'just' matter and using it in a way that seems right to us (and seeing ourselves that way too). And this had continued to our theology where we see Jesus and what he did as transactions, not as revelations of what was always true. We think God had to be changed by a sacrifice or other act, so we would receive something we wanted. Instead of Jesus in his life and death and resurrection expressing the heart of God in all eternities, and the mystery that we will find ourselves participating in if we just open our eyes. Needless to say, I am not the first person in the history of the Church to think about the sacramental nature of reality (even if those who think about this subject are more often found in catholic and orthodox circles). So here we have a theologian who pleads us, evangelicals and catholics both, to return to the sacramental worldview of the 'Great Tradition' - (before the year 1000 or so), when the mystery became visible because our world participated in it in a real way. This forces him to go against the grain, not only of our postmodern culture that seems superficially to embrace mystery but really embraces skepticism, but also of our theology, that for years now has argued against the perceived platonic influences in the early medieval world view. It's become hip to be against platonist influences, but well, do we not in the same way bring influences from our time into our theology? Boersma argues clearly that these early christians were not so uncritical to swallow Plato wholesale, but found ideas there to illuminate what they already perceived in Scripture, i.e. a much closer relationship between heaven and earth than had previously been imagined. And to them a two way interaction became important: by engaging with the world, they did truly engage with the mystery of heaven (that came to be expressed in the world), and by engaging with the mysteries of heaven, they gained a fuller understanding of this world and their roles in it. Just chucking these ideas out leaves us impovered. Not only do we lose sight in our imagination of the heavenly reality, the reality of the realm of God, but also we lose sight of the meaningfulness of earth, reducing everything to 'only matter'. Even we, ourselves, are dressed down to stimulus-respons automatons, or totally depraved creatures, unable to choose for good and God, that are surrendered to the whims of nature or God, both capricious. Leaning on mid 20th century French catholic theologions, he tries to point out a way forward, to a renewed weaving of the tapestry that is now being torn apart.
It's a fascinating thesis, as you will gather from my words here, but I do think the book (that is supposed to be a popular adaptation of the author's academic work) still keeps this too much a theory, and fails to show how the sacramental view would really, really change our lives, our churches, our world. It does not, to me, in itself convince me why I should want to desire this paradigm shift, and it still remains the province of theology, the way he describes it here. I must confess there were parts I found it hard to keep my attention focused. So it's up to others to translate these new directions of thought into practical application! I hope to play a role in this process somewhere!
