I have been really moved listening to this amazing podcast from Veritas by Mary Poplin (ignore the Q & A at the end). Mary was a radical Marxist/Feminist lecturer who found herself eventually investigating Mother Theresa, after an unshakeable dream where she encountered Christ and being disturbed by the peace a Native American Indian Christian believer who attended her class had. 

She speaks about the sisters of missionaries of charity in Calcutta under Mother Theresa. https://itunes.apple.com/gb/podcast/best-audio-veritas-forum/id497964119?mt=2&i=115964702

Two two things to look out for:

  1. How the sisters forgive Christopher Hitchin 
  2. How the sisters never ask for money yet millions flowed in.
