Not enough people are talking about Agamben’s Sacrament of Language. It’s inevitable and to some extent justified that it would be overshadowed by The Kingdom and the Glory, but Sacrament of Language provides a theoretical basis for the homology between theology and politics that structures K&G and is, in general, a very ambitious theory of religion. I’d imagine that many of the justifiable questions people have about K&G would be answered, or at least clarified, by reading Sacrament of Language. Plus it’s short!
So in conclusion, more people should read The Sacrament of Language. (And not just because I translated it. In fact, I only inquired about translating it because I thought it was important.)
