Each mark is one quotation. Touch the timeline to read it.

In 1517 Martin Luther published ninety-five theses on indulgences. This timeline begins with what led up to them: an old abuse that a council had warned against, Luther's years as an Augustinian friar and the struggle of conscience he describes, what he was writing before indulgences came up, and the indulgence preached for the building of St. Peter's. It then gives the theses, the Church's reply, what the Church later said had been wrong, and the reforms the Council of Trent made. After that it follows the teachings that set Protestants apart from the Catholic Church as each one is put forward. It also shows, step by step, how the Reformers and their confessions came to set seven books of the Old Testament outside the canon. Each of those entries links to the earliest witness on this site to what the Church already taught on that point, and to the full Catholic answer.

Drafted from primary sources. Every quotation is checked against the page it links to. An entry is the earliest statement of a teaching that could be quoted from a page this site can check, not the earliest that exists, and the notes on the entries name earlier texts we know of. Some of these teachings were put forward before 1517, by Berengar of Tours and John Wycliffe among others; this timeline does not show them. Zwingli's articles and the theses of Berne are quoted in Latin with our translation, because the linked page gives no English text.

Why the seven books were set apart: the Hebrew list, as St. Jerome gave it

St. Jerome Preface to the Books of Samuel and Kings

“This preface to the Scriptures may serve as a “helmeted” introduction to all the books which we turn from Hebrew into Latin, so that we may be assured that what is not found in our list must be placed amongst the Apocryphal writings. Wisdom, therefore, which generally bears the name of Solomon, and the book of Jesus, the Son of Sirach, and Judith, and Tobias, and the Shepherd are not in the canon.”

Three centuries before Luther: a council warns against the misuse of indulgences

Fourth Lateran Council Constitution 62

“Let those who are sent to seek alms be modest and discreet, and let them not stay in taverns or other unsuitable places or incur useless or excessive expenses, being careful above all not to wear the garb of false religion. Moreover, because the keys of the church are brought into contempt and satisfaction through penance loses its force through indiscriminate and excessive indulgences, which certain prelates of churches do not fear to grant, we therefore decree that when a basilica is dedicated, the indulgence shall not be for more than one year”

Luther becomes an Augustinian friar and a priest

Pope Benedict XVI Address to representatives of the Evangelical Church in Germany, Augustinian convent, Erfurt, 23 September 2011

“As we have just heard, this is where Luther studied theology. This is where he celebrated his first Mass. Against his father's wishes, he did not continue the study of Law, but instead he studied theology and set off on the path towards priesthood in the Order of Saint Augustine. And on this path, he was not simply concerned with this or that. What constantly exercised him was the question of God, the deep passion and driving force of his whole life's journey. "How do I receive the grace of God?": this question struck him in the heart and lay at the foundation of all his theological searching and inner struggle.”

A troubled conscience: Luther's own account of his struggle

Martin Luther Preface to the Complete Edition of Luther's Latin Works (1545)

“But I, blameless monk that I was, felt that before God I was a sinner with an extremely troubled conscience. I couldn't be sure that God was appeased by my satisfaction. I did not love, no, rather I hated the just God who punishes sinners. In silence, if I did not blaspheme, then certainly I grumbled vehemently and got angry at God.”

A hundred times worse blasphemies than this exist in the very streets of Jerusalem, and the high places are filled with spiritual idols.

“Now I would like to know whether your soul, tired of her own righteousness, would learn to breathe and confide in the righteousness of Christ. … Therefore, my sweet brother, learn Christ and him crucified; learn to pray to him despairing Of Yourself, saying: Thou, Lord Jesus, art my righteousness, but I am thy sin; thou has taken on thyself what thou wast not, and hast given to me what I was not. Beware of aspiring to such purity that you will not wish to seem to Yourself, or to be, a sinner. For Christ only dwells in sinners.”

The indulgence for St. Peter's: what Luther says the people were led to believe

Martin Luther Letter to Albrecht, Archbishop of Mainz, 31 October 1517

“Papal indulgences for the building of St. Peter's are circulating under your most distinguished name, and as regards them, I do not bring accusation against the outcries of the preachers, which I have not heard, so much as I grieve over the wholly false impressions which the people have conceived from them; to wit, -- the unhappy souls believe that if they have purchased letters of indulgence they are sure of their salvation; again, that so soon as they cast their contributions into the money-box, souls fly out of purgatory”

“it is the first and the sole duty of all bishops that the people should learn the Gospel and the love of Christ … it is said in the Instruction to the Commissaries which is issued under your name, Most Reverend Father (doubtless without your knowledge and consent), that one of the chief graces of indulgence is that inestimable gift of God by which man is reconciled to God, and all the penalties of purgatory are destroyed. Again, it is said that contrition is not necessary in those who purchase souls … or buy confessionalia.”

Luther's account of how his struggle ended: "the just person lives by faith"

“I meditated night and day on those words until at last, by the mercy of God, I paid attention to their context: "The justice of God is revealed in it, as it is written: 'The just person lives by faith.'"

The Church's reply: Luther's propositions on indulgences

Pope Leo X Exsurge Domine, condemned propositions 17 to 20

“17. The treasures of the Church, from which the pope grants indulgences, are not the merits of Christ and of the saints. 18. Indulgences are pious frauds of the faithful, and remissions of good works; and they are among the number of those things which are allowed, and not of the number of those which are advantageous. 19. Indulgences are of no avail to those who truly gain them, for the remission of the penalty due to actual sin in the sight of divine justice. 20. They are seduced who believe that indulgences are salutary and useful for the fruit of the spirit.”

“Luther's call for the reform of the Church was, in its original intention, a call to repentance and renewal, which have to begin in the life of each individual. That separation nevertheless came out of this beginning has many causes. Among them is that failure in the Catholic Church which Pope Adrian VI already lamented in moving words, as well as the intrusion of political and economic interests, but also Luther's own passion, which drove him far beyond what he first intended into a radical criticism of the Catholic Church, of her order of life and of her teaching. We have all taken guilt upon ourselves.”

Our translation. The words as written, in German:

“Luthers Ruf nach Reform der Kirche war in seiner ursprünglichen Absicht ein Aufruf zu Buße und Erneuerung, die im Leben eines jeden einzelnen zu beginnen haben. Daß dennoch Trennung aus diesem Anfang geworden ist, hat viele Gründe. Dazu gehört jenes Versagen in der katholischen Kirche, das bereits Papst Hadrian VI. mit bewegenden Worten beklagt hat sowie das Hereintreten politischer und wirtschaftlicher Interessen, aber auch Luthers eigene Leidenschaft, die ihn weit über das anfangs Gewollte hinaus in eine radikale Kritik der katholischen Kirche, ihrer Lebensordnung und ihrer Lehre hineingetrieben hat. Wir alle haben Schuld auf uns geladen.”

The Joint Declaration on the Doctrine of Justification

Pope St. John Paul II Angelus, 31 October 1999

“Representatives of the Catholic Church and the Lutheran World Federation are signing a Joint Declaration on one of the principal points which have divided Catholics and Lutherans: the doctrine of justification by faith. This is a milestone on the difficult path to re-establishing full unity among Christians, and it is highly significant that it is taking place in the exact city where in 1530 a decisive page in the Lutheran reform was written with the Augsburg Confession.”

Catholics and Lutherans mark five hundred years

Pope Francis and Bishop Munib Younan, President of the Lutheran World Federation Joint Statement on the occasion of the Joint Catholic-Lutheran Commemoration of the Reformation, Lund

“While we are profoundly thankful for the spiritual and theological gifts received through the Reformation, we also confess and lament before Christ that Lutherans and Catholics have wounded the visible unity of the Church. Theological differences were accompanied by prejudice and conflicts, and religion was instrumentalized for political ends.”
