There are saints who are the work of divine mercy, and who became greater saints by the power of mercy and by the constant homage they afterward rendered to it, than they would have been by innocence and virginity. Witness Saint Peter, far greater, far more devoted after his sin than before, also Saint Paul and Saint Magdalen. Their sanctity was nourished on mercy, their tears were the food of their love.
--St. Peter Julian Eymard
