Catholics use the word Magisterium often when discussing doctrine, papal teaching, ecumenical councils, and what the Church officially teaches. But the term can be confusing because it has several closely related meanings.
At its heart, the Magisterium is the teaching authority Christ gave to His Church. It can also refer to the pope and bishops who exercise that authority, or to the body of authoritative teachings handed on by the Church.
Understanding these distinctions helps answer important questions. Who has authority to teach in the Catholic Church? Is everything a pope says infallible? What is the difference between ordinary and extraordinary Magisterium? Are teachings that have not been declared infallible optional?
Quick Catholic Answer
The answer in one paragraph
The Magisterium is the teaching authority Christ entrusted to the Catholic Church. It is exercised by the pope and the bishops in communion with him to guard, interpret, and faithfully hand on the Word of God received through Scripture and Tradition. The Magisterium teaches with different levels of authority and can teach infallibly in certain circumstances.

01
What does Magisterium mean?
The word Magisterium comes from the Latin magister, meaning teacher. In Catholic usage, it names the Church’s God-given office of teaching the faith authentically.1
The term is commonly used in three related ways: for the authority to teach, for the pope and bishops who exercise that authority, and for the body of authoritative teaching that results from its exercise. Context usually makes clear which meaning is intended.
02
Who exercises the Magisterium?
The teaching office belongs to the bishops as successors of the apostles. They exercise it in communion with one another and with the Bishop of Rome, the pope, who is the successor of Saint Peter and the visible principle of unity among the bishops.3
The Pope
Teaches as the Church’s supreme pastor, either in ordinary acts or, under precise conditions, through a solemn definition.
The Bishops
Teach authentically in their dioceses and, united with the pope, share responsibility for the faith of the whole Church.
Ecumenical Councils
Gather the college of bishops with and under the pope to address the needs of the universal Church.
03
Ordinary and extraordinary Magisterium
These terms describe how the teaching office is exercised, not two separate authorities. Ordinary teaching is the Church’s regular work of instruction. Extraordinary teaching uses an especially solemn form.
Ecumenical councils provide important examples of the Church exercising this teaching authority. The Second Council of Nicaea, for example, clarified the distinction between the veneration given to saints and sacred images and the adoration owed to God alone.
| Form | How it is exercised | Can it be infallible? | Typical examples |
|---|---|---|---|
| Ordinary Magisterium | Regular teaching by the pope or bishops | Not necessarily | Encyclicals, homilies, diocesan teaching |
| Ordinary and Universal | Bishops worldwide, in communion with the pope, agree on a doctrine to be held definitively | Yes | Definitive teaching consistently held throughout the Church |
| Extraordinary Magisterium | A solemn definition by the pope or an ecumenical council | Yes, when defining faith or morals | Conciliar definitions and ex cathedra papal definitions |
04
When does the Magisterium teach infallibly?
Infallibility is a protection of the Holy Spirit that preserves the Church from error when she definitively teaches a doctrine of faith or morals. It is not a promise that every statement by a pope or bishop will be perfect, prudent, or free from every factual mistake.
A pope defines a doctrine ex cathedra. An ecumenical council with the pope solemnly defines a doctrine. The bishops dispersed throughout the world, united with the pope, agree that a teaching on faith or morals is to be held definitively.
The charism belongs to the teaching office for the sake of the whole Church. Its purpose is to protect the deposit of faith, not to make new revelation.
05
How are Catholics called to respond?
Catholic teaching is not divided simply into infallible statements and optional opinions. The response owed to a teaching depends on what is being taught, how definitively it is proposed, and the authority with which it is given.4
- 1
Divine and Catholic faith
Truths revealed by God and proposed as such by the Church are to be believed with the assent of faith.
- 2
Firm and definitive assent
Teachings required to safeguard and faithfully explain revelation are to be firmly accepted and held.
- 3
Religious submission
Other authentic teachings call for a sincere religious submission of intellect and will, even when they are not proclaimed by a definitive act.
06
How to read Church teaching well
Authority is discerned from more than a single phrase. Read the entire document, identify who issued it, note the document’s purpose and language, and consider whether the teaching repeats the Church’s constant witness.
A practical reading checklist
- What kind of document is this?
- Who issued it, and for whom?
- Is it defining a doctrine or explaining and applying one?
- Does it repeat teaching consistently held by the Church?
- What level of assent does the document itself indicate?
When uncertainty remains, the best approach is neither suspicion nor headline reading. Consult the Catechism, the full official document, and reliable Catholic scholarship that reads the statement within the Church’s living Tradition.

Frequently asked questions
Is everything the pope says infallible?
No. Infallibility applies only under specific conditions. Interviews, homilies, prudential judgments, and informal remarks do not automatically meet those conditions.
Can a bishop teach on his own?
A bishop is an authentic teacher for the faithful entrusted to him, but he teaches within the communion of the whole Church and with the pope.
Are non-infallible teachings optional?
No. Authentic teachings that are not proposed as definitive still call for religious submission of intellect and will, considered according to the authority and form of the teaching.
Can the Magisterium change revealed truth?
No. The Magisterium is not above the Word of God. Its task is to guard, explain, and faithfully hand on the deposit of faith.
Where should I look for official Church teaching?
Begin with the Catechism of the Catholic Church and the official texts of councils, popes, and the Holy See. Read individual statements in their full context and note the document type and intended audience.
