text: We cannot discern the truth for ourselves in opposition to what the Church teaches!  I recommend reading Vatican I documents.  
  
  "in matters of faith and morals, belonging as they do to the establishment of Christian doctrine, that meaning of Holy Scripture must be held to be the true one, which Holy Mother Church held and holds, since it is her right to judge of the true meaning of interpretation of Holy Scripture."  (Vatican I, Session 3  chapter 2, paragraph 8)
  
  "2. If anyone says that human studies are to be treated with such a degree of liberty that their assertions may be maintained as true even when they are opposed to divine revelation, and that they may not be forbidden by the Church: let him be anathema.
  3.  If anyone says that it is possible that at some time, given the advancement of knowledge, a sense may be assigned to the dogmas propounded by the Church which is different from that which the Church has understood and understands: let him be anathema" (Vat I, Cannons)
