Are the Pope and the Church really "Infallible"?

The topic of infallibility in the Catholic Church is an ironic one: although intended to provide clarity, it is one of the most misunderstood topics within Catholicism.
At least, humbly speaking, it was a big sticking point for me when I was a beginning Catholic. But once I understood it, I saw that it flows from a deep and beautiful faith in the active presence of the Holy Spirit in the Church.
What infallibility means
First of all, let’s start with the purpose of infallibility:
“It is this Magisterium’s task to preserve God’s people from deviations and defections and to guarantee them the objective possibility of professing the true faith without error…. To fulfill this service, Christ endowed the Church’s shepherds with the charism of infallibility in matters of faith and morals.” (Catechism, 890)
Infallibility is a gift of Christ and the Holy Spirit that gives us clarity and certainty about the faith itself and morality.
Infallibility just means that certain teachings of the Catholic Church are guaranteed to be without error. That’s not to say that they are the full and final word on the topic: later teachings may deepen and further clarify aspects of the original teaching.
(Some fundamental ideas about Catholic Tradition, the Catholic Church’s origin, and Church authority are covered in other articles here on You may find that those articles provide good background for the topic of infallibility.)
Exactly what teachings?
The charism of infallibility is fully engaged only in definitive Magisterial teachings on faith and morals. This can occur in either…
Ordinary teachings, or
Extraordinary teachings
The Magisterium is the teaching office of the Catholic Church. It is exercised by the Pope alone when he teaches officially, or by the whole “college” of bishops together with the Pope.
Most Magisterial teachings are ordinary. The Pope’s ordinary teachings are issued in the course his normal activity: his encyclicals and other documents, various addresses, etc.
The college of bishops also has an “ordinary and universal” Magisterium. This is seen whenever the individual bishops teach the same faith — that is, in union with the Pope and each other, even if they’re dispersed in their separate dioceses. It’s also seen when an ecumenical council teaches definitively but without issuing a solemn definition.
Occasionally, the Magisterium issues extraordinary definitions of doctrine. This occurs when the Pope teaches ex cathedra, officially and solemnly defining some truth of the faith. The official and solemn definitions of ecumenical councils (such as the Council of Trent, the First Vatican Council, etc.) are also extraordinary pronouncements.
Remember, it is the definitive teachings of the Magisterium that are considered to be infallible. This usually means that they explicitly state they’re defining some matter of the faith, or put forth a position as to be definitively held.
But not always.
Some things that are taught repeatedly by the Magisterium can also be considered definitive, even if they’re not explicitly named to be such.
Infallible teachings require the
Assent of faith
The Catholic Church uses its charism of infallibility to give the faithful clarity and certainty about morality and the faith itself.
As such, Catholics are required to give the “assent of faith” to such teachings. This means that our faith in them rests directly on our faith either in the Word of God, or in the Holy Spirit’s real & active assistance in the Magisterium.
We take that quite seriously!
How often are infallible teachings made?
You’ve probably heard a very common myth that infallibility has only been used a few times.
That is not the case!
It’s true that the Pope has exercised only rarely his own extraordinary power of defining the faith. But ecumenical councils have issued many extraordinary definitions over the years. And both the Pope and the full college of bishops have issued very many definitions in the course of their ordinary Magisterium. And of course…
…infallibility hinges on whether a teaching is definitive, regardless of whether it’s ordinary or extraordinary.
When people claim that infallibility is very rare, often they’re trying to justify their own rejection of some doctrine. They’re trying to minimize the number of cases where doctrine is binding.
But that’s exactly backwards!
The main job of bishops is to teach the Gospel. They do so with a special assistance of the Holy Spirit himself so that we may hear a faithful, accurate proclamation of the one true faith.
Although individual bishops may err in their official teachings about faith and morals, the Magisterium as a whole never does. Nor does the Pope, by nature of Christ’s special creation of Peter’s office as one that “confirms the brethren” in the faith.
Frequently, the Magisterium sees fit to define some point of doctrine so that we can see, understand, and hold it with great clarity. These definitions are infallible, and we must believe them with the assent of faith.
But much of the time, the Magisterium teaches without making such definitions. Are we free to ignore these teachings that are not infallible?
“Am I free to reject any
non-definitive teachings
that I don’t like?”
Not at all!
We must believe these teachings, too, although a lesser degree of belief is required. The technical expression is “a religious submission of mind and will”. This is less than the absolute assent of faith, but it still means that we must honestly strive to understand and accept these teachings.
As a practical matter, we should assume that the even Church’s non-definitive teachings are correct. They are still made with the assistance of the Holy Spirit, although not to the degree that guarantees that they’re free of error.
We should have very compelling, objective reasons before challenging such teachings. (And please note that the most frequent topics of dissent are not in this category! Topics like contraception, abortion, divorce, and homosexuality are all addressed by definitive Church teachings.)
Also remember that we tend to prefer our own flawed opinions, rather than admitting that we have to change.
This call to change is the hard and unending work of Christian discipleship. It’s known as conversion.
A gift of light & truth
Christ has given us an extraordinary gift in the Catholic Magisterium. It is the means by which Christ ensures that the light of his saving Gospel will shine on every generation.
When the Church teaches infallibly, it gives us great light & clarity.
But even in its non-definitive teaching, the Church still shines with the clear light of truth — a light that is far stronger than the darkness of the world.

  1. The question of infallibility applies to the Pope, not the Church. The Pope claims infallibility, but only on matters of faith and morals. That is all.

  2. Luis, please read the teachings of the Vatican I Council. That’s Vatican “One,” An official council of bishops, under the pope, is infallible when it defines the basic truths of the faith.

  3. The Pope is NOT the Church. The Church is the Mystical Body of Christ and the Truth established by Jesus and the Holy Spirit when the Church was established.
