St. Augustine wrote this work in the closing years of a life busied with three great controversies--Manichaeism, Donatism, Pelagianism, the last ending with the Contra Julianum and the Opus imperfectum contra Julianum.

Chapter 4
 
(. . .)
 
Of the number of the elect and predestined, even those who have led the very worst kind of life are led to repentance through the goodness of God, through whose patience they were not taken from this life in the commission of crimes; in order to show them and their co-heirs the depth of evil from which the grace of God delivers man. Not one of. them perishes, regardless of his age at death; never be it said that a man predestined to life would be permitted to end his life without the sacrament of the Mediator. Because of these men, our Lord says: 'This is the will of him who sent me, the Father, that I should lose nothing of what he has given me.'11 The other mortals, not of this number, who are of the same mass as these, but have been made vessels of wrath, arc born for their advantage. God creates none of them rashly or fortuitously, and He also knows what good may be made from them, since He works good in the very gift of human nature in them, and through them He adorns the order of the present world. He leads none of them to the wholesome and spiritual repentance by which a man in Christ is reconciled to God, whether His patience in their regard be more generous or not unequal. Therefore, though all men, of the same mass of perdition and condemnation, unrepentant according to the hardness of their heart, treasure up wrath to themselves on the day of wrath when each will be repaid according to his works, God through His merciful goodness leads some of them to repentance, and according to his judgment does not lead others. Our Lord says He has the power to lead and draw men: 'No men can come to me unless the Father who sent me draw him.'12

2.  I am filled, I confess, with bitter grief, not only because the death of Valentinian has been premature, but also because, having been trained in the faith and moulded by your teaching, he had conceived such devotion towards our God, and was so tenderly attached to myself, as to love one whom he had before persecuted, and to esteem as his father the man whom he had before repulsed as his enemy.

4.  But hereafter we shall have time for sorrow; let us now care for his sepulture, which your Clemency has commanded to take place in this city. If he has died without Baptism, I now keep back what I know.

Will he not then receive the grace which he desired and obtain what he asked for?

invincible ignorance

First, as regards the intellect, man receives certain supernatural principles, which are held by means of a Divine light: these are the articles of faith, about which is faith.

7. Here, too, our beloved sons and venerable brothers, it is again necessary to mention and censure a very grave error entrapping some Catholics who believe that it is possible to arrive at eternal salvation although living in error and alienated from the true faith and Catholic unity. Such belief is certainly opposed to Catholic teaching. There are, of course, those who are struggling with invincible ignorance about our most holy religion. Sincerely observing the natural law and its precepts inscribed by God on all hearts and ready to obey God, they live honest lives and are able to attain eternal life by the efficacious virtue of divine light and grace. Because God knows, searches and clearly understands the minds, hearts, thoughts, and nature of all, his supreme kindness and clemency do not permit anyone at all who is not guilty of deliberate sin to suffer eternal punishments.

19.

(. . .)

Let us pray that the errant be flooded with the light of his divine grace, may turn back from the path of error into the way of truth and justice and, experiencing the worthy fruit of repentance, may possess perpetual love and fear of his holy name.

(. . .)

Do men like these pour forth their prayers to God that in His mercy he may bring to the Divine light of the Gospel by His victorious grace the people sitting in the darkness?

2. Therefore, guided by the example of Our predecessors, We are grieved to hear reports from your dioceses which indicate that some of the people committed to your care freely encourage mixed marriages. Furthermore, they are promoting opinions contrary to the Catholic faith:


(. . .)


Finally some of these misguided people attempt to persuade themselves and others that men are not saved only in the Catholic religion, but that even heretics may attain eternal life.
