According to The Raw Story/AFP, Pope Francis said yesterday:

" 'The communists have stolen our flag. The flag of the poor is Christian. The poor are at the heart of the Gospel,' he said in an interview published on Sunday.
"He cited the Beatitudes, the opening verses of the Sermon on the Mount, as an example of where Christianity had influenced communism.
" 'The communists say that all this is communism. Yeah, right, twenty centuries later. So one can say to them: but then you are Christian,' the pope said while laughing, according to the interview in Rome daily Il Messaggero."

Fair enough. Take your flag back, comrade. Don't leave it lying around again... and canonize the man: it's only fair!
