On 8 September 1572 a procession of thanksgiving took place in Rome, and the pope, in a prayer after mass, thanked God for having "granted the Catholic people a glorious triumph over a perfidious race" (gloriosam de perfidis gentibus populo catholico loetitiam tribuisti)..."When the first rumours of the massacre reached the Vatican in Rome on 2 September 1572, pope Gregory XIII was jubilant and wanted bonfires to be lit in Rome. He was persuaded to wait for the official communication. The very morning of the day that he received the confirmed news, the pope held a consistory and announced that "God had been pleased to be merciful". Then with all the cardinals he repaired to the Church of St. Mark for the Te Deum, and prayed and ordered prayers that the Most Christian King might rid and purge his entire kingdom (of France) of the Huguenot plague.
And yet some tell us we're overly-sensitive.
