The Body, the Eucharist, Sacraments and Symbols

I've mentioned that a lot of what I do read is the movement known as Radical Orthodoxy. What I do severely enjoy about it's corpus of writtings is how they engage with contemporary philosophical,political and cultural issues ranging from the destructive habits of late capitalism to a theology of the body.

It is the theology of the body which challenges me the most. Mainly because their theological account of gender,marriage and sexuality is centred around the Sacrament of the Eucharist. Having listened to their arguments and been somewhat of an observer of the discourse I can say that I do really desire to have the same understanding of the Eucharist as they do simply because from the point they are able to narrate a different world, a 'city of God' so to speak. From that point they are able to talk about Bodies in a meaningful way because they hold a sacramental view of the Eucharist.

So now I'm stuck. I want to engage with a discourse and theology on bodies but now have been forced to really think and pray about what the Eucharist really means.
