Girolomo Savonarola: A Fiery Italian Reformer and Martyr

The Basilica Santa Maria Novella lies in the very center of Florence, Italy–it is such a beautiful, inspiring, and majestic city!

Written by Dr. Marcus J. Serven

“For we are an aroma of Christ to God among those who are perishing, to one a fragrance from death to death, to the other a fragrance from life to life.” 2 Cor. 3:15-16

Who was Girolamo Savonarola (A.D. 1452-1498)? Briefly stated, he was an Italian monk and preacher who arose just prior to the Reformation. Savonarola was under Dominican orders and vows throughout his adult life (from 1474); although he grew somewhat more independent as he became better known throughout Italy. Born in Ferrara, from 1482 he made his home and base of operations in Florence. There he became the Prior of the convent of San Marco and began to preach in the cathedral. Church historian, S. M. Houghton observes,

But whereas Wycliffe and Huss were involved in attacking the unbiblical teachings of the Roman Catholic Church, Savonarola was not a doctrinal reformer. He was a man who attacked the evil lives and immoral habits of many of his fellow countrymen. God had used the writings of Augustine of Hippo to open his eyes to the moral apostasy in the Church.

— S. M. Houghton, Sketches in Church History, 72

One artist’s depiction of Girolamo Savonarola preaching his message of reform to the people of Florence, Italy

He called the city and the Roman Catholic Church to moral reform by a series of scathing sermons on a coming Apocalypse. This apocalyptic theme, which he garnered from reading the Old Testament prophets and the Book of Revelation, dominated his preaching and became his lifetime message. For example Savonarola proclaimed in one fiery sermon, “In the primitive church the chalices were of wood, the prelates of gold; in these days the church hath chalices of gold and prelates of wood.” This kind of direct confrontation of church leaders brought forth both praise from some and opposition from others. Moreover, Savonarola embraced an early version of the doctrine of biblical authority (Lat. Sola Scriptura = “by Scripture Alone”) and called the Church to reject the authority of the Pope by looking to the Bible alone.

Girolamo Savonarola in his maturity (1452-1498)

In 1494 Charles VIII, King of France, sent his armies ravaging throughout Italy and twice spared Florence due to Savonarola’s requests. The people of Florence interpreted this to be an example of God protecting the city from judgment. Savonarola used this “victory” to call for further moral reforms in Florence, which were enforced at times with a strong hand—for example during the Carnival of 1496 many profane and lewd books were publicly burnt in a “bonfire of vanities.” Some people welcomed these changes, but others resisted his efforts at reformation. He was openly opposed by the rival Franciscans, and by citizens who were still loyal to Piero de’ Medici (who had fled when Charles VIII threatened the city with destruction).

Pope Alexander VI (1431-1503)

Pope Alexander VI (also known as Alexander Borgia) responded to Savonarola’s criticisms of the Roman Catholic Church by threatening to place Florence under an interdict if they allowed Savonarola to continue his preaching. The Pope referred to Savonarola as “that meddlesome friar” and in 1497 excommunicated him. Savonarola responded with the charge that the Pope was “a representative of Satan not of Christ.” This led to Savonarola’s arrest in 1498, a trial for sedition and heresy, an extensive time of torture, and finally on May 23 a martyr’s death. Between episodes of torture he wrote meditations on Psalm 32 and 51, which Martin Luther later published and referred to them as “a piece of evangelical testing and Christian piety.” At his execution, Savonarola was stripped of his priestly vestments. The presiding Bishop said, “I separate thee from the church militant and from the church triumphant.” Savonarola boldly replied, “Militant, not triumphant, for you have no power to separate me from the church triumphant to which I go.” He was then hanged, and his body was burned at the stake. His remains, and those of two other men who were killed alongside of him, were thrown into the river Arno so that no relic of his life could be preserved. Dr. Howard F. Vos summarized Savonarola’s life with these words,

While Savonarola demanded reform in the church, he never took the more advanced position of Wycliffe and Huss. He had no quarrel with the teaching or the organization of the church, but seems to have believed in justification by faith. He was characterized by religious zeal and personal piety.

— Howard F. Vos, Who’s Who in Christian History, 607-608

Thus, a remarkable man passed from the scene. Yet, his energetic preaching, biblical teaching, and personal zeal laid the ground work for the Reformation which would spring forth into existence from the religious awakening of another monk in twenty years time–and that man was Martin Luther.

Here is the execution of Savonarola in the public square of Florence (May 23, 1498). In God’s providence he preceded the beginning stages of the Reformation by twenty years. Many of the Protestant Reformers greatly esteemed him!

B. B. Warfield on the Doctrine of Assurance

Archibald Alexander Hall at Princeton Theological Seminary

“The Spirit himself bears witness with our spirit that we are children of God, and if children, then heirs–heirs of God and fellow heirs with Christ…” Rom. 8:16-17a

A close family friend sent this powerful quotation from Dr. Benjamin B. Warfield to one of my family members who has been struggling with her health. What an encouragement it was to her and to all of us! This citation is from a sermon given by Dr. Warfield in Miller Chapel to his students at Princeton Theological Seminary. Over the course of his lengthy ministry of teaching systematic theology in the classroom (1887-1921), he also passionately exhorted his students from the pulpit. Let me share it with you…

Dr. B. B. Warfield (1851-1921)

“If God be for us who can be against us?” (Rom. 8:31) Let our hearts repeat this cry of victory today. And as we repeat it, let us go onward, in hope and triumph, in our holy efforts. Let our slack knees be strengthened and new vigor enter our every nerve. The victory is assured. The Holy Spirit within us cannot fail us. The way may be rough; the path may climb the dizzy ascent with a rapidity too great for our faltering feet; dangers, pitfalls are on every side. But the Holy Spirit is leading us. Surely, in that assurance, despite dangers and weakness, and panting chest and swimming head, we can find strength to go ever forward.”

— Warfield, Biblical and Theological Studies, 558

I pray the Lord will encourage and strengthen you to go forward by faith in the Christian life. The Holy Spirit who dwells within you, is stronger than all of the temptations and trials of this present world (1 Cor. 3:16 and 6:19-20; 1 John 4:4). His presence in our life is a great blessing, and one that we should regularly remind ourselves of. Recall as well, this ringing exclamation: “If God be for us who can be against us?” (Rom 8:31)

A Reformation Day Sermon: “The Lord is our Fortress” Psalm 46

The Wartburg Castle near Eisenach, Germany, is where Dr. Martin Luther was safely held for nearly a year in 1521-1522

“The LORD of hosts is with us; the God of Jacob is our fortress.” Psalm 46:11

Yesterday, I had the opportunity to preach for Reformation Sunday at Redeemer Presbyterian Church (PCA) here in Austin, Texas. We have four pastors at Redeemer, and since I am the only one who is “semi-retired” I usually preach once or twice a year. Instead, my main role at Redeemer is focused on teaching. I regularly instruct adults in our School of Discipleship classes on Sunday mornings. Beyond that, I am the director of Redeemer Theological Academy teaching college-level courses in Biblical studies, Systematic Theology, Church History, Apologetics, and Ministry. This suits me quite well, and I am grateful to focus my energies on teaching at this point in life. Nonetheless, below is an audio file of my most recent sermon. Also, you will find an introduction to the sermon and an outline of the text. I hope you enjoy it!

“The Lord is our Fortress” – Psalm 46:1-11

Direct, succinct, and pastoral–it is hard to beat Derek Kidner’s fine commentary on the Psalms.

Introduction: The image of a “fortress” or “stronghold” in relation to the Lord shows up in many passages in the Old Testament (e.g. 2 Sam. 22:1-4; Ps. 9:9; 18:2; 31:3; 71:3; 91:2; 144:2; Prov. 18:10; Jer. 16:19). It is a portrait of strength, security, and safety for the people of God. Indeed, the Lord is the only one who could provide such protection in times of trouble. He is the one who created all things and also controls all things (Ps. 103:19). Essentially, this word-picture of a “fortress” and “stronghold” teaches us the doctrine of the sovereignty of God. In other words, we can believe that when everything in our world seems to be falling apart we can take comfort from the fact that all things are firmly under the control of the Lord. Even when misfortunes come our way, or when wickedness is exalted, we can be confident that “The Lord has made everything for its purpose, even the wicked for the day of trouble” (Prov. 16:4). This doesn’t mean that we never experience any difficulties and trials in life. It does mean, however, that God is in the midst of these difficulties and trials, and that he is able to bring good out of them (Rom. 8:28). Let us, then, go forward as those who trust in the sovereign rule of the Lord over all things in our own personal circumstances and in the tumultuous events of this world. Soli Deo Gloria!

Here is an outline of my sermon:
1. The Lord is our Refuge and Strength, (vs. 1-3)
2. The Lord is the Source of All Blessings, (vs. 4-5)
3. The Lord is the Ruler of the Nations, (vs. 6-9)
4. The Lord is the King of His Saints, (vs. 10-11)
