     preme value of the human person at every stage 
    
 
     
     of life. All of society can be enriched thanks to 
    
 
     
     this dialogue, which opens up new horizons for 
    
 
     
     thought and expands the possibilities of reason. 
    
 
     
     This too is a path of harmony and peace. 
    
 
     
     243.âThe Church has no wish to hold back the 
    
 
     
     marvellous progress of science. On the contra- 
    
 
     
     ry, she rejoices and even delights in acknowledg- 
    
 
     
     ing the enormous potential that God has given to 
    
 
     
     the human mind. Whenever the sciences â rig- 
    
 
     
     orously focused on their specific field of inquiry 
    
 
     
     â arrive at a conclusion which reason cannot 
    
 
     
     refute, faith does not contradict it. Neither can 
    
 
     
     believers claim that a scientific opinion which 
    
 
     
     is attractive but not sufficiently verified has the 
    
 
     
     same weight as a dogma of faith. At times some 
    
 
     
     scientists have exceeded the limits of their scien- 
    
 
     
     tific competence by making certain statements or 
    
 
     
     claims. But here the problem is not with reason 
    
 
     
     itself, but with the promotion of a particular ide- 
    
 
     
     ology which blocks the path to authentic, serene 
    
 
     
     and productive dialogue.

     the prayer of the Lord Jesus that âthey may all 
    
 
     
     be oneâ ( 
    
 
     
      Jn  
    
 
     
     17:21). The credibility of the Chris- 
    
 
     
     tian message would be much greater if Christians 
    
 
     
     could overcome their divisions and the Church 
    
 
     
     could realize âthe fullness of catholicity prop-
