11 You are quite familiar with the events which took place at Lourdes at that time, the spiritual proportions of which are better measured today. You know, Beloved Sons and Venerable Brethren, the astonishing circumstances under which the voice of that child, the messenger of the Immaculate, compelled the world's recognition despite ridicule, doubt, and opposition. You know the steadfastness and purity of her testimony, wisely put to the test by episcopal authority and approved as early as 1862.
