While currently writing an article about Mother Theresa, it occurred to me that "sainthood" means different things to different people. The Vatican has a process and it requires a number of miracles performed in the name of the saint. but guess what - some saints have been "fast tracked" and other have histories that you would not consider seemly for sainthood.
Add to the fact that the Christian Right HATED Mother Theresa and LOATHED Princess Diana for the good works they did. They consider them a plot by :THE QUEEN OF HEAVEN" (demonic, of course) to carry out Satan's bidding.
Oh, and they think the QUEEN reside on Mount Everest.
