I sat in Glasgow Royal Infirmary last summer and the consultant told me that I had cancer: stage 4, aggressive and incurable. When people said they would pray for me, I asked if they would do so through the intercession of Venerable Margaret Sinclair. She needs a miracle, I would tell them. I knew that the Vatican Congregation for the Causes of Saints had looked into the case of Venerable Margaret, a poor Edinburgh girl turned nun, and concluded a miracle was still needed in order for her to be declared a Blessed.
