Firstly Louise Bagshawe said that it was irrelevant that Mother Teresa opposed birth control and abortion. Her point was that as a Catholic of course she opposed these things and that as canonisation was a Catholic honour it is up to Catholic leaders (or indeed God) to make the decision on how good a Catholic she was.
But that's total rubbish. If a branch of Islam decided to canonise (or the equivalent) a suicide bomber she would be the first one on her high horse condemning that decision. Mother Teresa did not spend her life at home praying and affecting no-one else - she was deeply involved in international politics and her actions and efforts on birth control and abortion as well as the reprehensible way she ran her so-called charity caused totally unnecessary suffering and death to people around the world. In fact she caused much more human suffering and death than any suicide bomber ever did. If (when) the Catholic church chooses to canonise her any self-respecting Catholic should leave the faith and those who don't should expect to be on the receiving end of serious criticism.
Secondly the guy who claimed to have had his mental health problems cured miraculously after he prayed to Mother Teresa. Isn't it interesting how those who experience miracle healing always seem to have conditions where there are other secular cases of those same conditions spontaneously righting themselves? You show me a guy who prayed to Mother Teresa and his missing leg grew back and I will line up with the faithful!
