One of the complaints that Catholics commonly throw at Protestants is that their doctrine of “Private Interpretation” leads to doctrinal anarchy: When you’re doing theology with a mindset of “The Bible, the Holy Spirit and Me” it’s inevitably going to lead to massively inflated egos, widespread doctrinal disagreements and an intensely burning pride.

What I recently realised is that Catholics are almost in the same boat as Protestants. The fact that Catholics have a magisterium doesn’t necessarily change anything: in the end Catholic theology boils down to “private interpretation”. The question needs to be asked however; private interpretation of what? I will answer this question shortly.

Sheep and Shepherds

It seems apparent to me that there are basically two ways to “do religion”. The first involves just accepting and familiarising yourself with whatever the church officially teaches, without questioning or disagreeing with anything. If you are being a Catholic in this way, you don’t necessarily “switch off your brain”, as you may very well try to wrestle with the doctrines presented to you and try to make sense of them, but you do go with the flow and just subscribe to official teaching without question. The Catechism of the Catholic Church is particularly important to someone doing Catholicism in this way, as it clearly spells out exactly what the church teaches on pretty much every issue. Often when arguing with someone who “does Catholicism” in this way, they will throw quotes from the Catechism at you as if doing so definitively settles the issue and totally closes the argument: “no more discussion necessary, the church has spoken, case closed”.

People who follow this first path are actually are to be commended. This way of approaching Catholicism is actually entirely appropriate for the majority of Christians. It is simply a brute fact of life that not everyone has the time, inclination and calling to wrestle with 2000 years of church tradition, scripture, biblical languages, theology and philosophy. Not everyone is called to be a theologian or an exegete. Not everyone is called to study the bible. However everyone is called to submit to Christ, and to the church which he founded. We are the sheep and they are the shepherds. The sheep’s duty is simple: follow the shepherd wherever the shepherd may lead. In this way, it is entirely appropriate to fall back on the official interpretations of the church, which have been distilled and refined over 2000 years and represent the sensus fidelium at the current point in time. It is a brute fact of life that most people don’t have the time to engage in theology; their time is largely occupied by the hard work and more pressing issue of being a good programmer, plumber, carpenter, student, doctor etc. For such people, it is a blessing to have an official interpretation which they can depend on for their faith, whilst being active and occupied in the “real world”.

Discerning the Light

There is however a second way of “doing Catholicism”, this way is the path of the theologian. The theologian recognises that the official interpretation of the church is not infallible. The theologian understands that the sensus fidelium is not infallible. The theologian knows that the Pope is not infallible. The theologian always keeps in mind that the Catechism is just one fallible voice among many.

Rather than simply following whatever the church says, the theologian has decided to embark on a much more difficult journey: a journey which involves familiarising himself with 2000 years of church documents, writings of the church fathers, scripture translations and editions, biblical and liturgical languages, philosophy, theology and so on.

The theologian is entirely justified in disagreeing with the official teaching of the church. The theologian is more acutely aware of the limits and bounds of infallibility. If there is something suspect in the official teaching of the church, he will call it out.

If you are following this second path, you have already entered into the realm of “private interpretation”: what you end up believing will probably be completely different to what everyone else believes. And yet despite this the problem of “doctrinal anarchy” which plagues Protestantism will not be a problem for you. The reason why is that Catholicism is a dogmatic system which has something akin to continuing revelation which I refer to as Divine Clarification. Despite the fact that the deposit of faith was “once for all delivered to the saints”, it is not a static thing: it is something which grows and develops with time.

The Deposit of Faith

It is helpful to first establish what a historical-critical Protestant believes to be the Deposit of Faith. Such a Protestant believes that the original Greek and Hebrew manuscripts of the 66 books of the reformation bible are the entire deposit of faith. Case closed. If you are a protestant theologian this is all you need to work with. Learn Hebrew, Learn Greek and get down to the hard work of exegeting scripture. Translations are helpful but they hold a lesser authority to the original languages and can therefore be safely discarded when doing serious theology.

I would like to register a reservation with this perspective before moving on. Firstly, we no longer have access to the original Greek and Hebrew manuscripts. We only have critical editions and copies of copies, all of which differ with each other. Protestants often respond to this by saying that the differences are “insignificant”. I personally am unimpressed with this line of argument, as it would imply that parts of sacred scripture can be safely discarded, which is surely a blasphemous conclusion. While we can have confidence that our critical editions are close to the originals, we have no actual infallible guarantee that this is the case, and there is therefore a cloud of uncertainty constantly hovering over such versions of scripture.

In any case, this is the protestant version of the deposit of faith: the 66 book canon, read in the original languages.

Compare this with the Catholic deposit of faith. The Catholic deposit of faith is a massive behemoth to behold. A Catholic does not merely have to concern himself with the scriptures in their original languages; he also has to take into account all translations of the scripture which have been implicitly received by an apostolic tradition or explicitly approved by the magisterium of the church. In this way, a Catholic does not have to work with a single bible or a single translation; he instead has to take into account a massive plethora of translations and editions. The Vulgate has authority, but the Septuagint with Greek New Testament holds equal authority. The Peshitta has authority, but the RSV-CE holds equal authority. Approved Spanish editions of Scripture are just as inspired and authoritative as approved French editions. The more languages a Catholic theologian knows, the more of the deposit of faith he is able to familiarise himself with and therefore the more effectively he is able to do theology.

But the Catholic deposit of faith doesn’t end there. The only reason that scripture is inspired, is that it is read in the context of the Divine Liturgy. The received apostolic liturgies of the church are inspired by the Holy Spirit: God speaks through the liturgy well before he speaks through scripture. But this only makes the Catholic theologian’s job even harder: not only does he have to concern himself with all the approved editions of scripture, he also has to be familiar with all the different apostolic and approved liturgies that are to be found throughout the world and within the church! And of course, a liturgy is not something that can be experienced by reading a book; it is not something which you can understand just by watching it on Youtube or reading about it on Wikipedia; a liturgy has to be lived and breathed. You must participate in the liturgy and pray through it. You must be physically present. If you’re lucky enough to live in a city like Sydney, many of these liturgies can be found within a 50km radius. However if you’re living out in the country side, you’ll be lucky to get a single Latin Mass.

But wait, there’s more! The Catholic deposit of faith has another component: the dogmatic tradition. The dogmatic tradition is the Divine Clarification which I mentioned earlier. This dogmatic tradition consists of all the infallible statements produced by ecumenical councils and all ex cathedra statements pronounced by Popes. A Catholic theologian has to take this entire tradition into account and do justice to it.

To review: Both the Catholic and the Protestant theologian are engaging in private interpretation. The only difference is the scope of the “raw data” that the respective theologians have to deal with. A Protestant theologian only has to deal with 66 Greek and Hebrew books, whereas a Catholic theologian has to deal with a multitude of scriptural translations, a plethora of divine liturgies and 2000 years of dogmatic pronouncements.

The Strength of Catholicism

After reading the previous section, you might think that the Protestant is better off: he doesn’t have to deal with so much raw material during his theological inquiries. However there’s one important difference between these two conceptions of the deposit of faith: The Protestant version is entirely static, whereas the Catholic version is dynamic.

As the collective Catholic understanding of the deposit of faith grows, this understanding is codified and added back in to the deposit of faith itself in the form of a fresh dogma. After this happens, future theologians are forced to take the new dogma into account during their theological adventures. The dogma is set in stone, it can never be revoked (although perhaps it may be “annulled” if there is doubt surrounding whether or not it was ever officially promulgated). This keeps the Catholic church moving forward in it’s understanding: as the church encounters controversies and issues, it deliberates and investigates and comes to a conclusion; this conclusion is then codified in a dogma and inserted into the dogmatic tradition, where it will remain forever. This is how doctrinal development occurs.

Consider for a moment what would happen if everyone were following the “first way” of doing Catholicism described above. There would never be any development! Everyone would just accept the churches current interpretation of the deposit of faith and not try to push the envelope to any degree. This is why – ironically – private interpretation is actually a crucial component of Catholic theological development. Individual people who are following the “theologian” path all come together, raise issues, argue with each other, start up passionate debates. This sometimes leads to massive controversies in the church, at which point the magisterium steps in and declares a dogma, definitively deciding between the two parties.

This process of dogmatic Divine Clarification also forces theologians to stay largely on the same page and avoid the doctrinal anarchy which so plagues Protestantism. Even though theologians may disagree on important issues, they are forced to work within the same dynamic deposit of faith, and this keeps them in agreement on issues that the magisterium has already dogmatically pronounced on. They may disagree on the interpretation of the deposit of faith, however they cannot deny the deposit of faith itself.

Compare all of this with the static Protestant system: The Protestant system is entirely unable to respond to change and is prevented from developing. The protestants have a battle cry – “Semper Reformanda” – which is supposed to be taken as a call for the church to be “always reforming”. In theory this is supposed to imply a rejection of all dogma, however in practice most if not all Protestants have their own “pet doctrines” which they cling to dogmatically and will not budge from even when shown contradictory evidence.

In any case, the Protestant deposit of faith is entirely static: it cannot respond to fresh questions that are posed of it. They have no magisterium which can introduce new and authoritative clarifying dogmas into the religion. They are stuck in the past. They are forced to depend entirely upon the fallible historical-critical method for all of their exegetical attempts. They deny the inspired voice of the church in the present age. All of this results in a church community which is constantly going around in circles and reinventing the wheel. Where Catholics have dogmatically defined the Trinity and the divinity of Christ, the Protestants are constantly having to rediscover these ideas afresh in the pages of scripture. Unfortunately, due to their over-reliance on the entirely fallible historical-critical method, many Protestants have begun to jettison many of these crucial Christian ideas. Many Christians have become Unitarians, or modern day Arians, denying the divinity of Christ. Unlike Catholicism, there is no “dogmatic spine” holding up the Protestant theological body. Protestants agree on the same deposit of faith, but beyond that they are free to disagree with each other at the level of interpretation and they are doomed to disagree with each other until Jesus comes back. Again, compare to the Catholic system: Catholic theologians may disagree with each other for a time, but as the ages march on and the magisterium declares more and more dogmas, the theologian’s many and varied opinions will coalesce into a single infallible interpretation.

Conclusion

To summarise: The Catholic deposit of faith is large and multifaceted, encompassing all received and approved bible translations, all apostolic liturgies and all infallible statements within the dogmatic tradition. When a Catholic theologian is doing theology, he has to take this entire deposit of faith into account. The end result is a form of Private Interpretation that is restricted and guided by the dogmatic tradition. However rather than being destructive and dangerous for the church, this limited private interpretation is a crucial component of doctrinal development and serves to drive the church forward towards theological perfection.
