The pope beatified mother teresa, putting her into line for sainthood. This Salon article calls into question her worthiness, noting her apparent hypocrisy and possible insanity:

During the deliberations over the Second Vatican Council, under the stewardship of Pope John XXIII, MT was to the fore in opposing all suggestions of reform. What was needed, she maintained, was more work and more faith, not doctrinal revision. Her position was ultra-reactionary and fundamentalist even in orthodox Catholic terms. Believers are indeed enjoined to abhor and eschew abortion and contraception, but they are not required to affirm that abortion and contraception are the greatest threat to world peace, as MT fantastically asserted to a dumbfounded audience when receiving the Nobel Peace Prize.
