Devoted to the truth or ours?

Following on from my last post on John's prologue, I read this from the Emergent Village Minemergent daily communique. What do people think of this?

The Danger of Devotion to Truth 

Any truth elevated to a status above its purpose is, by definition, self-destructive and divisive. Truths will always serve us, but they can only take us so far and they are never arbitrary. Those truths we accept are those we accept precisely because they are most efficient at expressing the love that brings the Divine into presence with us. Otherwise, we are left with simple ideas which lack any power to move us. Our beliefs are permitted to change. It is the purpose and standard of our beliefs that must remain constant and to which we owe allegiance. It is not devotion to evil, but devotion to truth that has been present at every slipping of the Church.
