In Christian theology, the cross is the symbol of deconstruction.
The gospels portray Jesus as so truthful that he lived this reality through to its inevitable conclusion: his own crucifixion. Paul developed and articulated the theology through to its logical conclusion: the rejection of him, his letters, his gospel and his Jesus by the earliest church.
The whole bible is permeated with this issue. Every writer wrestles with this perplexity. Why will every thought that exalts itself be pulled down? Why does the faith carry within it the seeds of its own destruction? Why must everything end up at Golgotha, there to be tried, tested, tortured and threatened with termination? Why is anything that is something menaced by nothingness? And why is only nothingness promised to be left alone and perhaps, in due time, exalted?
These are questions that harassed the biblical writers and should unsettle the church today.
