Jan Hus on the Church: Scripture Alone as the Only Foundation
The previous installment of [root.log] examined the life of Jan Hus. This one turns to his theology. If his biography establishes Hus as a forerunner of the Reformation, his theological writings make the case beyond dispute. The organizing principle of his entire body of work is the same rallying cry that would define the Reformation a century later: Sola Scriptura. Hus was not simply a dissident cleric irritated by institutional corruption. He was a churchman who understood that the only way to rebuild the church was to place it once again upon the Word of God. What follows is an examination of three pillars of his theological project: his ecclesiology, his doctrine of Scripture, and his theology of ministry.
Christ Alone Is Head of the Church
The most significant of Hus's surviving works is De Ecclesia — On the Church. In it, he defines the church with a precision that cuts against everything Rome had come to assume about itself:
The church is the house of God, in which priests minister to his worship. According to the meaning of Christ, the church encompasses the entire congregation under the law of Christ — and within it there are two churches: the predestined and foreknown, the sheep and the goats.
Hus draws a foundational distinction between the visible, institutional church on earth and the invisible church of God — the body of those truly elected and known by him. The universal church, he insists, is the mystical body of Christ, and Christ alone is its head. This ecclesiology is thoroughly Augustinian and tracks closely with Wycliffe's position. More pointedly, it dismantles the logic by which medieval Rome had fused its hierarchical apparatus with the church of God itself. Hus presses further: among those who presently appear to belong to the elect, there may well be those who will ultimately be excluded from God's eternal grace.
Though by worldly reckoning many claim to be the head or members of the church, in truth before God they are limbs of the devil.
Hus saw that the lives of popes and priests bore no resemblance to the lives of men and women redeemed by Christ. They were Christians in name only. This was a direct assault on Rome's claim that the pope constituted the church's head and the senior clergy its body. Hus was unsparing: those who occupy the highest seats in the visible church may find themselves last in the kingdom of God. His ecclesiology was, at its core, a theological indictment of a clergy marked by financial corruption, sexual dissolution, and habitual drunkenness — men whose lives gave the lie to every claim they made about their own spiritual authority.
Scripture: The Supreme Rule of Faith and Life
Shaped decisively by Wycliffe's approach to the Bible, Hus insisted on Scripture as the sole and supreme authority of the church. He opposed, consistently and publicly, every papal decree that contradicted the Word — including the growing body of documents being assembled to prop up the doctrine of papal infallibility. He was blunt about what Rome was doing: the pope and the senior clergy were weaponizing Scripture to protect their own power, distorting it beyond recognition. Against this, Hus declared that the law of God alone — Scripture — must be the standard by which the church judges all things.
The very structure of De Ecclesia demonstrates this conviction. Hus cites Scripture on nearly every page. The claim that the Bible is the supreme rule of faith and practice was not, for him, an abstract principle — it was the method by which he actually did theology. Nothing marks him more clearly as a herald of the Reformation.
Hus held that Scripture, as the Word of God, brings the human mind into contact with truth itself. When a person receives that truth — not merely as an intellectual proposition but as something grasped by the whole person — it generates a willing obedience that flows outward into life and action. This is why Hus was convinced that the Scriptures must be placed directly in the hands of ordinary believers. In 1406, he put that conviction into practice by publishing a Czech-language Bible — comprising the complete New Testament, the Psalms, and Proverbs — known as the St. Mikulovský Bible.
The Marks of a True Minister
Hus wrote De Simonia — On Simony — in 1413 under circumstances that give the work its particular urgency. Excommunicated and driven into exile in the countryside, he could no longer stand before the congregation of Bethlehem Chapel in Prague. He reached them instead through writing. In this text, Hus identifies three heresies that he regards as the most destructive forces at work in the church: apostasy — turning away from the law of God; blasphemy — the desecration of holy faith; and simony — the exchange of spiritual goods for material ones. Each is a betrayal of a different dimension of the sacred order. Simony, he argues, is a heresy that destabilizes the very structure of the church.
Simony is a spiritual leprosy, exceedingly difficult to cure apart from a special act of divine grace. And because it is contagious, the simoniac infects others. Faithful Christians must therefore contend against it vigorously. But since it cannot be resisted without being understood, simony must be exposed — openly, and without apology.
The priesthood, in Hus's day, was one of the most reliable paths to social prestige and material comfort. He traced the pattern of simony back to two biblical figures: Gehazi, who attempted to receive payment for Elisha's healing of Naaman; and Simon Magus, who tried to purchase from the apostles the power to confer the Holy Spirit by the laying on of hands. In these two men, Hus saw the prototype of every minister who treats sacred office as a commodity.
The one who enters the priesthood in hope from God does so in order to teach people to believe in God, to keep his commandments, and to pray to him rightly.
The minister Hus envisions is not a man managing a career. He is a man whose entire existence is reoriented around the glory of God and the spiritual welfare of those entrusted to his care. He lives honestly, after the pattern of Christ. He puts away pretension, vice, and luxury. He conforms himself to Christ in obedience, and offers to him every act of faith, hope, love, and good work — becoming thereby a living example to the flock. The standard Hus sets is nothing less than the fullness of the stature of Christ.
What Hus Still Demands of Us
The theology of Jan Hus does not stay in the fifteenth century. It follows us.
His doctrine of Scripture remains a standing challenge. What every Christian is finally accountable to is not the opinion of a celebrated pastor or the output of a popular theologian — it is the Word of God. Our faith and our lives must be measured against Scripture itself, not against the shifting standards of the age. In an era when artificial intelligence is producing unprecedented volumes of plausible-sounding misinformation, the temptation to be carried along by whatever authority happens to be loudest is not trivial. The only answer is what it has always been: Sola Scriptura — Scripture as the only lamp by which we walk.
His ecclesiology is a warning that church membership and ecclesiastical office provide no shelter on the day of judgment. Pastors and elders are not exempt from this reckoning by virtue of their positions. Salvation comes only through genuine union with Christ — through receiving him as Lord, belonging to the church of which he is the head, and being incorporated into his body. To forget this is to become, in practice, no different from the corrupt prelates Hus spent his life opposing.
His theology of ministry speaks with particular directness to those whose hands hold institutional power — denominational officials, seminary trustees, church leaders contemplating the transfer of congregations to their children. A seminary treated as a revenue stream is not categorically different from what Hus called simony. Ecclesiastical inheritance is not categorically different either. The question Hus presses is not comfortable: what exactly are you in this for?
The final answer he gives is the one the Reformers all gave. The core of the faith is Scripture — and the purpose of a life lived under Scripture is to walk, in all things, according to the will of God and for his glory alone. As the saints before us confessed, we are strangers and pilgrims on this earth, moving toward a homeland that is not here. That is what the Christian life is. Hus knew it. He died for it. We would do well not to forget it.
