text: I concede that I am surprised by this quotation. In a first draft of my reply, I referenced the Church's economic teaching more broadly (which is what I really mean to say!), but then edited it to conform to you specific reference to Leo (yes, the pope ;-} )
  
  That said, we are into some major verbal game-man-ship here. "Socialism" is a much broader term today than Leo's definition premised on the "community of goods." In my view, socialism and capitalism must be seen as a continuum. and their is no modern capitalist economy that does not have socialistic elements deeply embedded. 
  
  Also it is not unimportant that extreme forms of socialism have central places in Catholic life--the first Christian community as described in Acts, and all religious orders with vows of poverty. are "socialism" by Leo's definition.
