From the Selected Letters of St. Ignatius:
Seeing the progress that the heretics have made in so short a time, spreading the poison of their evil teaching throughout so many countries and peoples, and making use of the verse of the Apostle to describe their progress, and their speech will eat its way like gangrene [2 Tim. 2:17], it would seem that our Society, having been accepted by Divine Providence among the efficacious means to repair such great damage, should not only be solicitous in preparing the proper remedies but should be ready to apply them, exerting itself to the utmost of its powers to preserve what is still sound and to restore what has fallen sick of the plague of heresy, especially in the northern countries.
The heretics have made their false theology popular and presented it in a way that is within the capacity of the common people. They preach it to the people and teach it in the schools, and scatter pamphlets that can be bought and understood by many; they influence people by their writings when they cannot reach them by preaching. Their success is largely due to the negligence of those who should have shown some interest, and the bad example and the ignorance of Catholics, especially the clergy, have made such ravages in the vineyard of the Lord. Hence it would seem that our Society should use the following means to end and cure the evils which the Church has suffered through these heretics.
