text: "Ergo, non-Catholic religious leaders are ignorant of logic and reason." is an example of a logical error.
  
  I do believe that most Protestants understand that Catholics do not see eye-to-eye on a number of beliefs, and therefore would not consider a Catholic as not welcoming who disagrees.
  
  Or do you think ecumenism involves heading for the lowest common denominator?
  
  That could present some issues, because in some denominations - e.g., the Episcopal Church - belief that Jesus Christ was literally the Son of God is optional.
