Decretum (Concord of Discordant Canons)

Abstract
Problem. By the twelfth century the Church's rules lay scattered across many compilations of decrees from councils, popes and Fathers, and these often clashed with each other. Judges and bishops had no single, ordered book to consult.
Method. A Bologna teacher arranged thousands of texts by subject and added his own remarks, asking questions and drawing distinctions that showed how apparently opposed rules applied to different situations. This pattern of question, objection and resolution became the model for teaching in the new universities.
Natural law. The opening section ranks the moral law found in Scripture, summed up in the Golden Rule, above custom and enacted rules. Where custom or legislation contradicts that higher law, the lower rule must yield.
Cases. The middle part poses three dozen imaginary disputes on buying Church offices, property, marriage, heresy, war and repentance, each followed by questions. The questions train students to reason from authorities to decisions in particular disputes.
Sacraments. The last section collects texts on church buildings, baptism, the Eucharist and worship. These texts gave the Church a common reference for its liturgy and discipline.
Influence. Glossed in the schools and supplemented by papal decrees, the compilation became the core of the Church's legal code until 1917 and shaped European ideas of consent in marriage, fair procedure and rights. Modern research shows the book grew in two stages, probably through the work of its compiler and his first pupils.

Summary
The Decretum of Gratian, whose own title was the Concord of Discordant Canons (Concordia discordantium canonum), is the founding textbook of canon law, the law of the Western Church. It was compiled at Bologna around 1140, at the same time that teachers there were reviving the study of Justinian's Roman law. Before Gratian, the Church's law was scattered in many collections of canons from councils, popes and Church Fathers, which often contradicted one another. Gratian gathered several thousand of these texts and tried to show how they could be reconciled. His method was new. He arranged the texts by topic, and between them he wrote his own comments, called dicta, in which he posed questions, set authorities against each other and proposed distinctions that resolved apparent conflicts: one canon applies in one circumstance, another in another; one states a general rule, another an exception. This method of reasoning by question and distinction shaped medieval university teaching in law and theology alike. The Decretum has three parts. The first, in 101 Distinctions, treats the sources of law and the clergy. It opens with the distinction between natural law and human custom, teaching that natural law is contained in the Law and the Gospel, which command each person to do to others what he would have done to himself, and that natural law takes precedence over custom and enacted law. The second part presents 36 Causes, imaginary cases each raising several questions, on topics such as simony, Church property, marriage, heresy, just war and penance. The third part treats the sacraments and worship. The Decretum was never officially promulgated by a pope, but it became the standard text in the schools. Teachers wrote glosses on it, popes issued new decretals to supplement it, and together these formed the Corpus of Canon Law, in force in the Catholic Church until the Code of 1917. Through canon law the Decretum influenced European ideas of marriage by consent, due process, natural rights and the limits of rulers. Recent scholarship has shown that it grew in at least two stages, so the work is best understood as the product of Gratian and his early students.
Plot or Argument
- Part I: Distinctions on law
Natural law, custom and enacted law; the sources of Church law; ordination and the clergy.
- Part II: Causes
Thirty-six hypothetical cases on simony, property, marriage, heresy, war and penance, each with questions.
- Treatise on penance
A long theological discussion set within Part II.
- Part III: On consecration
Texts on churches, the sacraments and worship.
- Method
Gratian sets conflicting authorities side by side and reconciles them with his own comments.
Lessons
Reconciling authorities
Gratian took contradictory texts seriously and sought distinctions that showed how they fit together. Careful reasoning can find harmony where others see only conflict.
- How did Gratian handle canons that disagreed?
- When two authorities seem to conflict, how should we decide between them?
Natural law first
Gratian taught that natural law, found in the Law and the Gospel, outranks custom and human legislation. Human law must answer to God's law.
- What does Gratian say natural law commands?
- Why should custom give way to natural law?
Law in the Church
The Decretum shows that the Church needed order and justice in its own life. Law can serve charity when it protects the weak and settles disputes fairly.
- What kinds of cases did the Decretum address?
- How can law serve love?
Context
In the early twelfth century, Bologna became the centre of a revived study of Roman law. Church reformers had also produced many new collections of canons to support the independence and discipline of the Church.
Composition
Gratian compiled the work around 1140. Scholarship since 2000 has shown an earlier, shorter version and a later, expanded one.
Reception
The Decretum quickly became the basic text of canon law in the universities. Commentators called decretists glossed it, and it remained part of the Church's law until 1917.
Comparisons
- The Institutes of Justinian
The Roman law revived at Bologna alongside Gratian's canon law.
- Summa Theologica
Aquinas, a century later, built on the medieval discussion of natural law that Gratian helped begin.
- Magna Carta
Magna Carta was drafted by men, including Stephen Langton, trained in the law and theology of the schools.

Faith Connections
- Matthew 7:12 (Scripture)
"All things whatsoever ye would that men should do to you, do ye even so to them": the Golden Rule Gratian identifies with natural law.
- Acts 5:29 (Scripture)
"We ought to obey God rather than men": divine law above human law.
- Isidore of Seville, Etymologies V (Church Fathers)
Gratian draws his definitions of natural and human law from Isidore.
Logic and Rhetoric
Central argument: Conflicting Church laws can be harmonized by careful distinctions, and all human law is subordinate to natural law found in the Law and the Gospel.
Rhetorical device: distinction. Gratian resolves conflicts by showing that each authority applies in different circumstances.
Debate: Resolved: that unjust laws are not truly laws.
