“Question:
Could you please tell me what is Justification and Sanctification and does the Catholic understanding on these topics differ from Protestants?
Answer:
Whole books have written on this subject, so I will provide a basic overview, distinguishing between the basic Catholic view and the fundamental Protestant view first advanced by Martin Luther.
Catholics and Protestants agree that God’s grace is fundamental and indispensable to our eternal salvation as Christians. And that initial justification—i.e., when we first come into relationship with Jesus Christ—is a completely unwarranted divine gift (John 15:16; CCC 1989-92).
In short, the Church teaches that God inwardly heals and transforms us by his grace, making us children of God (CCC 1262ff.). This is initial justification, which takes place in baptism. So baptism gives us a share in divine love or “righteousness,” an infused “theological virtue” which enables us to become like Jesus and do his will in a lovingly obedient way (CCC 1991). Baptism restores our communion with God and is the beginning of our salvation, the first step on a lifelong journey.
Through initial justification, from the Catholic perspective, God obligates us to abide in him (John 14:15) and grow progressively in holiness (see Matt. 5:43-48). This progressive growth after initial justification is known as ongoing justification or sanctification. In ongoing justification or sanctification, we continue to grow in the theological and human virtues, with Jesus as our model. This is not “works righteousness” or “salvation by works” as the Church’s teaching is sometimes caricatured. Works alone, as the heretic Pelagius was reminded by the Church in the 400s, can never save. And works apart from grace cannot even contribute to our salvation. Indeed, our good works only have “merit”—including graces for ourselves and others to grow in holiness and help attain eternal life—because they are rooted in and aided by Christ’s love (CCC 2006–16), so that we might persevere in God’s grace instead of rejecting his gift of salvation. And if we are baptized after the age of reason, even the choice to receive baptism is a good work, again aided by God’s grace.
Luther believed that justification took place by baptism, including infant baptism, something with which most modern Protestant don’t agree, favoring instead a nonsacramental “believer’s baptism.” In addition, in harmony with many modern Protestants, Luther saw God as a judge who makes a legal declaration about our righteousness, our being free from sin in some sense, but who doesn’t inwardly heal and transform us by his grace, let alone call us to a life of deepening holiness. For Luther, the original sin of our first parents injured human nature so badly that we are “totally depraved,” i.e., incapable of doing any good at all, or at least not able to do good works that impact our eternal salvation. Indeed, a fundamental plank of Luther’s soteriology is that man’s will is enslaved. From this conviction comes Luther’s doctrine of “justification by faith alone,” meaning our “good works” cannot possibly impact our eternal destiny, and that only by a total repudiation of God (loss of faith) can we lose our salvation.
For Luther, the baptismal “regeneration” St. Paul taught (Titus 3:5) means the removal of the eternal punishment of sin through the justifying faith associated with baptism, and thus it opens heaven to the justified (Martin Luther, The Large Catechism, “Holy Baptism,” nos. 41–46, 83). However, a justified person’s human nature remains totally depraved for Luther, and original sin and an individual’s personal sins are not blotted out; so communion with God is restored but in a lesser way than our first parents originally enjoyed. One needs to keep these distinctions in mind when Luther teaches that Baptism brings about the “forgiveness of sin.” (Ibid., nos. 41, 86).
Because Luther believed man’s will was enslaved, when God is “in the saddle” vs. the devil, man can perform works of sanctification, whereby the Holy Spirit makes us more like Christ in all we think, desire and choose. But if the devil prevails, man inevitably chooses wrongly.”

Chesterton, “When we pray we speak to God; but when we read, God speaks to us.” -St Jerome, "As the reading of bad books fills the mind with worldly and poisonous sentiments; so, on the other hand, the reading of pious works fills the soul with holy thoughts and good desires." -St. Alphonsus Liguori, "And above all, be on your guard not to want to get anything done by force, because God has given free will to everyone and wants to force no one, but only proposes, invites and counsels." –St. Angela Merici, “Yet such are the pity and compassion of this Lord of ours, so desirous is He that we should seek Him and enjoy His company, that in one way or another He never ceases calling us to Him . . . God here speaks to souls through words uttered by pious people, by sermons or good books, and in many other such ways.” —St. Teresa of Avila, "I want a laity, not arrogant, not rash in speech, not disputatious, but men and women who know their religion, who enter into it, who know just where they stand, who know what they hold and what they do not, and who know their creed so well that they can give an account of it, who know so much of history that they can defend it. I want an intelligent, well-instructed laity… I wish you to enlarge your knowledge, to cultivate your reason, to get an insight into the relation of truth to truth, to learn to view things as they are, to understand how faith and reason stand to each other, what are the bases and principles of Catholicism, and where lie the main inconsistences and absurdities of the Protestant theory.” (St. John Henry Newman, “Duties of Catholics Towards the Protestant View,” Lectures on the Present Position of Catholics in England), "We cannot always have access to a spiritual Father for counsel in our actions and in our doubts, but reading will abundantly supply his place by giving us directions to escape the illusions of the devil and of our own self-love, and at the same time to submit to the divine will.” —St. Alphonsus Ligouri, "The harm that comes to souls from the lack of reading holy books makes me shudder . . . What power spiritual reading has to lead to a change of course, and to make even worldly people enter into the way of perfection." –St. Padre Pio, "Screens may grab our attention, but books change our lives!" – Word on Fire, "Reading has made many saints!" -St Josemaría Escrivá, "Do you pray?

And this I believe is heard.” -GM Hopkins, SJ, "Only God knows the good that can come about by reading one good Catholic book." — St. John Bosco, "Why don't you try explaining it to them?" – cf St Peter Canisius, SJ, Doctor of the Church, Doctor of the Catechism, "Already I was coming to appreciate that often apologetics consists of offering theological eye glasses of varying prescriptions to an inquirer. Only one prescription will give him clear sight; all the others will give him at best indistinct sight. What you want him to see—some particular truth of the Faith—will remain fuzzy to him until you come across theological eye glasses that precisely compensate for his particular defect of vision." -Karl Keating, "The more perfectly we know God, the more perfectly we love Him." -St Thomas Aquinas, OP, ST, I-II,67,6 ad 3, “But always when I was without a book, my soul would at once become disturbed, and my thoughts wandered." —St. Teresa of Avila, "Let those who think I have said too little and those who think I have said too much, forgive me; and let those who think I have said just enough thank God with me." –St. Augustine, "Without good books and spiritual reading, it will be morally impossible to save our souls." —St. Alphonsus Liguori "Never read books you aren't sure about. . . even supposing that these bad books are very well written from a literary point of view. Let me ask you this: Would you drink something you knew was poisoned just because it was offered to you in a golden cup?" -St. John Bosco " To teach in order to lead others to faith is the task of every preacher and of each believer." —St. Thomas Aquinas, OP. "Prayer purifies us, reading instructs us. Both are good when both are possible. Otherwise, prayer is better than reading." –St. Isidore of Seville “The aid of spiritual books is for you a necessity.… You, who are in the midst of battle, must protect yourself with the buckler of holy thoughts drawn from good books.” -St. John Chrysostom
