human vision corrected by divine love

"What a priceless thing for the poor converts of a savage country!" he exclaimed, wiping his glasses, which were clousded by his strong feeling. "All these poor Catholics who have been so long without instruction have at least the reassurance of that visitation. It is a household word with them that their Blessed Mother revealed Herself in their own country, to a poor convert. Doctrine is well enough for the wise, Jean; but the miracle is something we can hold in our hands and love." 

Father Vaillant began pacing restlessly up and down as he spoke, and the Bishop watched him, musing. It was just this in his friend that was dear to him. "Where there is great love there are always miracles," he said at length. "One might almost say that an apparition is human vision corrected by divine love. I do not see you as you really are, Joseph; I see you through my affection for you. the Miracles of the Church seem to me to rest not so much upon faces or voices or healing power coming suddenly near to us from afar off, but upon our perceptions being made finer, so that for a moment our eyes can see and our ears can hear what is there about us always."
