The outstanding Swiss theologian, who reached the biblical age of 93, died in his house in Tübingen last Tuesday.
  
    
    
    
      Hans Küng
      was one of the best-known church critics in the German-speaking world. He repeatedly criticized the structures of his Catholic Church and expressed doubts about the dogma of papal infallibility.
  
    
 
  
It is no wonder that the Church revoked Küng's teaching license in 1979, but
  he remained at the University of Tübingen as a faculty-independent professor
  of ecumenical theology. 
Red Baron is always interested in the
  fundamental question, "Why do we exist?" So, Küng became my trusted and loyal comrade in my search for God.
  
  Here are some of his books (from left to right) that I read: 
On Being a Christian
  (1974), 
Judaism: Between Yesterday and Tomorrow (1992), 
Christianity: Its
  Essence and History (1995), 
Islam: Past, Present, and Future (2007), 
Eternal
  Life: Life after Death As a Medical, Philosophical, and Theological Program
  (1984), 
Credo: The Apostle's Creed Explained for Today (1993), 
What I Believe
  (2010), and 
The Beginning of All Things—Science and Religion (2007).
There
  is an anecdote. During a three-month scientific stay at the High Energy
  Accelerator Research Center (KEK) in Japan in 1980, I stowed the heavy volume 
On Being a Christian in my luggage to study it carefully while at KEK.
On
  February 8, an article titled "
Kueng: Member of the Loyal Opposition" appeared in 
The Japan Times. It informed about the ousting of Küng as a professor of Catholic theology. The paper's tenor and most letters to the editor harped on the Church's inquisitional attitude. 
On the other hand, in a letter to the editor, Red Baron deplored Rome's inflexibility. I claimed that changing times require a fresh interpretation of the gospel. For me, Küng was a modern evangelist, a herald of good tidings. 
In the early 1990s, Küng
  initiated his project 
Weltethos, of which he became president. Küng
  described the Global Ethic Project's goal as "Peace among religions, cultures,
  and nations based on some common elementary ethical values, standards, and
  attitudes."

  Here
  is a picture from those younger years: Mayor
  
Boris Palmer, Old-Chancellor
  
Helmut Schmidt, and President of the Global Ethic Foundation Hans Küng (from left to right)
  on May 8, 2007, in Tübingen on the occasion of the "Global Ethic" speech
  organized by Küng and delivered by Schmidt. Palmer still serves as Mayor of
  Tübingen.
The query "Why do we
  exist?" still haunts me. In 2005, after finishing Küng's book 
Der Anfang aller Dinge (The Beginning of All Things), I felt fit to address the
  religious war on evolution, giving a talk on 
Intelligent Design  versus Darwinism at the Freiburg-Madison-Gesellschaft.
In
  2010, I read Küng's book 
Was ich glaube (What I Believe) and was later deeply disappointed by 
Stephen Hawking's
  book 
The Grand Design.
In
  December 2012, after more input to my religious quest, I concluded with the
  Beatles, "
All you need is love."
Again, in December, but two years later, I read an article about "
True Religion."
  When I finished, I repeated the author's conclusion, "All religious
  movements are based on faith; and faith, which is belief in the absence of
  convincing evidence, isn't true or false, but simply irrational."
But
  there is hope. My favorite astrophysicist, 
Neil deGrasse Tyson, published 
Cosmic Queries, StarTalk's Guide to Who We Are, How We Got Here, and Where
    We're Going.
If Neil doesn't answer the query, "Why do we exist?" will he at least teach me where we are going? I am eagerly waiting for 
Cosmic Queries to become available as an e-book.
