Oh, you DO LOVE TO BELIEVE THAT, don't you?  Only God is infallible!  We've had too many mistakes by some popes/hierarchy who believed that they were infallible.  They only succeeded in painting the Church into a corner that, even after long passages of time, the Church still cannot get out.  And the entire Church suffers for this delusionary belief. 
 

Better for the leaders in the Church to admit that they have been and ARE very fallible in how they view issues and in how they "call issues".  The analogy used in the article is very apt and 'on target'.
