The Council of Trent and the Counter Reformation

Historical Theology

Historical Setting

Rome did not stand still while the Reformation spread. After decades of delay — owing to war between France and the Empire, papal reluctance to convene a council that might limit papal power, and the sheer scale of the crisis — the Roman Catholic Church gathered at Trent, a town in northern Italy, for the great council that would answer the Reformers and reform much of Rome’s own life. The Council of Trent met in three periods (1545–1547, 1551–1552, 1562–1563) and produced the most authoritative statement of Roman doctrine since the Middle Ages. It defined Catholicism over against Protestantism for the next four hundred years, until the Second Vatican Council.

Alongside Trent ran a broader Counter-Reformation: the founding of the Jesuits, a renewal of preaching and spirituality, the cleansing of genuine abuses, the Roman Inquisition, and a vigorous missionary expansion. Rome was wounded but far from dead; it answered with both reform and resistance.

What Was at Stake

At stake was the very definition of the gospel. The Reformers had recovered justification by faith alone, on the imputed righteousness of Christ, on the authority of Scripture alone. Trent had to decide whether these were a legitimate development within the church or a heresy to be condemned. Its answer would determine whether the breach could ever be healed. And the answer, in the end, was condemnation — Trent did not merely differ from the Reformers; it pronounced them anathema.

Key Players

Pope Paul III, who finally convened the council, and his successors who guided it.

The assembled bishops and theologians, drawn largely from Italy and Spain, with Dominican and Jesuit advisors shaping the debates.

Reginald Pole and the more reform-minded prelates, some of whom were privately sympathetic to a doctrine of justification close to the Reformers’ — but who lost the argument.

Ignatius of Loyola (1491–1556), founder of the Society of Jesus, whose disciplined, educated, missionary order became the spearhead of Catholic renewal.

Charles Borromeo and others who implemented Trent’s reforms — seminaries, episcopal residence, catechesis.

The Outcome

State Rome’s position accurately and in its strongest form, for charity and truth require it.

On Scripture and tradition. Trent declared that the gospel is contained “in written books and unwritten traditions,” received “with equal feeling of piety and reverence.” It affirmed the Vulgate as the authentic text and reserved to the church the right to judge the true sense of Scripture. Rome did not despise the Bible; it held that the same Spirit who inspired Scripture also guides the church’s tradition, and that Scripture cannot rightly be read apart from the church that received and canonized it. Against Protestant “private judgment,” this seemed to Rome a needed safeguard.

On justification. Here Trent’s Decree (1547) is careful and, in its way, magnificent. Rome affirmed that justification is by grace, that no one can be saved apart from Christ, and that grace is wholly unmerited at its beginning. But it taught that justifying grace is infused into the soul, renewing the person inwardly, so that the believer is not merely declared righteous but made righteous; that this grace must be cooperated with; that justification can be increased by good works and lost by mortal sin and recovered through the sacrament of penance; and that “faith formed by love” (fides caritate formata), not faith alone, justifies. Trent’s canons then anathematized the evangelical position point by point:

“If anyone says that justifying faith is nothing else than confidence in the divine mercy… let him be anathema.” (Trent, Session 6, Canon 12)

“If anyone says that the sinner is justified by faith alone… let him be anathema.” (Trent, Session 6, Canon 9)

On the sacraments and the Mass. Trent affirmed seven sacraments, reaffirmed transubstantiation, and defined the Mass as a true and propitiatory sacrifice offered for the living and the dead — a re-presentation of Calvary’s offering.

The Counter-Reformation also brought real renewal: seminaries to train clergy, the Roman Catechism, the suppression of the cruder abuses that had provoked Luther, and a missionary surge that carried Catholicism across the globe.

Scriptural Grounding

The Reformed reply to Trent rests where the Reformation began — on Paul’s forensic gospel.

“For we hold that one is justified by faith apart from works of the law.” (Rom. 3:28)

“And to the one who does not work but believes in him who justifies the ungodly, his faith is counted as righteousness.” (Rom. 4:5)

“Now to the one who works, his wages are not counted as a gift but as his due.” (Rom. 4:4)

“For Christ also suffered once for sins… that he might bring us to God.” (1 Pet. 3:18); “we have been sanctified through the offering of the body of Jesus Christ once for all.” (Heb. 10:10)

Doctrinal Significance

Trent matters because it defined the division. Before Trent, one might hope the church would receive the recovered gospel as a legitimate reform. After Trent, the lines were drawn in formal dogma and sealed with anathemas. The decisive issue was justification. Where Scripture presents justification as a forensic verdict — God declaring the believing sinner righteous on the ground of Christ’s imputed righteousness, received by faith alone — Trent fused justification with sanctification, making the verdict depend on grace infused and cooperated with and never finally assured. On the Mass, where Scripture presents Christ’s sacrifice as once for all, Trent made it a continuing propitiatory offering. These are not differences of emphasis but of the gospel itself.

“Faith… is the alone instrument of justification; yet is it not alone in the person justified, but is ever accompanied with all other saving graces.” (WCF 11.2)

A Reformed Assessment — Wheat and Chaff

Charity first. Trent was not the work of cynics; it labored seriously over Scripture and the Fathers, it reformed genuine corruptions, and it confessed much that is true — the necessity of grace, the centrality of Christ, the renewal of the believer. The Counter-Reformation’s missionary zeal and pastoral renewal shame the lethargy of many a Protestant church. We do not sneer at Rome; we recognize a body that took doctrine with deadly seriousness.

Yet the chaff is grave, for here Trent hardened against the gospel. By anathematizing justification by faith alone and the assurance it brings, Trent struck at the comfort of the troubled conscience that the Reformation had restored. By making the verdict depend on infused grace and cooperation, it left the sinner forever uncertain — the very ache Luther had escaped. By defining the Mass as a propitiatory sacrifice, it obscured the finished, once-for-all offering of Christ. We judge, soberly and not triumphantly, that on the article by which the church stands or falls, Trent placed the Roman communion in formal opposition to the apostolic gospel — and that its anathemas, never rescinded, still stand against the doctrine we believe Paul preached.

Lessons for Today

Trent teaches that earnest religion, even much true doctrine, and genuine reform of life can yet miss the gospel at its center if justification is confused. It warns that the church’s authority, when set above the Word, will defend even its errors with anathemas. It models, in the Counter-Reformation’s vigor, a missionary and pastoral seriousness Protestants should envy and imitate. And it summons us to hold the doctrine of justification with both clarity and charity — clear that the gospel is at stake, charitable toward those still bound, never triumphant, always praying that the light recovered in the Reformation would shine into every communion that bears Christ’s name.
