It is obvious that the concept of truth has become suspect. Of course it is correct that is has been much abused. Intolerance and cruelty have occurred in the name of truth. To that extent people are afraid when someone says, “This is the truth”, or even “I have the truth”. We never have it, at best is has us. No one will dispute that one must be careful and cautious in claiming the truth. But simply to dismiss it as unattainable is really destructive.(…) We must have the courage to dare to say: Yes, man must seek the truth; he is capable of truth. It goes without saying that truth requires criteria for verification and falsification. It must always be accompanied by tolerance, also. But then truth also points out to us those constant values which have made mankind great. That is why the humility to recognize the truth and to accept it as a standard has to be relearned and practiced again. The truth comes to rule, not through violence, but rather through its own power; this is the central theme of John’s Gospel: When brought before Pilate, Jesus professes that he himself is The Truth and the witness to the truth. He does not defend the truth with legions but rather makes it visible through his Passion and thereby also implements it.
