If God causes you to suffer much, it is a sign that He has great designs for you, and that He certainly intends to make you a saint. -St. Ignatius of Loyola
Joseph suffered great afflictions and trials from his brethren, and these formed precisely the way by which the Lord led him to his great exaltation.
There is no better test to distinguish the chaff from the grain, in the Church of God, than the manner in which sufferings, contradiction, and contempt are borne. Whoever remains unmoved under these, is grain. Whoever rises against them, is chaff; and the lighter and more worthless he is, the higher he rises, — that is, the more he is agitated, and the more proudly he replies. -St. Augustine
St. Teresa, who was formed for so lofty a destiny, suffered incredible trials from all sorts of people, even from the good and spiritual. Many considered her deluded by the devil. Many ridiculed her prayers and revelations. Some wished to exorcise her as possessed. Others accused her to the Holy Office; and she suffered, besides, much opposition and trouble from her Superiors, in regard to the monasteries which she founded.
There is no more evident sign that any one is a saint and of the number of the elect, than to see him leading a good life and at the same time a prey to desolation, suffering, and trials. -St. Aloysius Gonzaga
