By Fr. Armand de Malleray, Catholic Exchange - Years ago, I used to offer Mass (according to the traditional Roman Missal) for Mother Teresa’s Sisters, the Missionaries of Charity, in London. When visiting the sick in India, those Sisters would evaluate distances neither in metric nor in imperial measurements, but in Ave Marias. One can imagine an instruction to a new Sister: “You will have time to pop in at poor Mrs Aaradhka’s, as she lives only three decades from the convent.”
