This is something I’ve posted in another thread and it may be useful to understand dogma and changes within the Church.
…
I would advocate that whenever theological deliberations are discussed as it pertains to dogma, doctrine and discipline, there are level of theology certainty (corroborated in *Fundamentals of Catholic Dogma) *that need to be ascribed to them, which are as follows:
De fide**:** Divine revelations with the highest degree of certainty, considered infallible revelation.
Fides ecclesiastica: Church teachings, which have been definitively decided on by the Magisterium, considered infallible revelation.
Sententia fidei proxima: Church teachings, which are generally accepted as divine revelation but not defined as such by the Magisterium.
Theologica certa: Church teachings without final approval but clearly deduced from revelation.
Sententia communis: Teachings which are popular but within the free range of theological research.
Sententia probabilis: Teachings with low degree of certainty.
Opinio tolerate: Opinions tolerated within the Catholic Church, such as pious legends.
Only
de fide and
fides ecclesiastica statements are infallible. As long as these do not change, there isn’t any theological quandrary for the Church. If you are interested in the definitive list of Catholic dogmas (
de fide and
fides ecclesiastica) I recommend
Fundamentals of Catholic Dogma by Dr. Lugwig Ott. It shows the sources in Scripture, Tradition and Papal/Council decrees. After reading this book, I’ve come to the conclusion no infalliable dogmas have changed despite many assertions to the contrary by Church critics.
Infallible teachings mandate full assent of faithful and dissent is not permitted. Non-infallible teachings require the religious submission of will and intellect but dissent (e.g. debate) on
specific points on a matter of faith or morals is
possible because the doctrine is not necessarily free from error. However,
only elements* not essential* to salvation can there be
permissible dissent and then* only* when there is basis within Tradition, Scripture and Magisterium and not merely prevalent opinion or personal interpretation.
In other words, dissent is possible if…
- There is a basis to do so within Tradition, Scripture and the Magisterium
- It pertains to matters not related to salvation
- It is not merely due to popular opinion or ideology outside the Church
- It is not on Church Dogma (which is infallible)
Hence, if you intend offer a dissenting opinion on
non-salvation points of matter, you will need to back it up within the desposit of Tradition, Scripture and the Magisterium (citing documents with a nihil obstat and imprimatur; not third party documents or websites) and fulfill the above requirements. Remember, only teaching points at the theologica certa, sententia communis and sententia probabilis theological levels can, in theory, be debated.
De fide and fides ecclesiastica statements are not changeable and are deemed infallible. Sententia fidei proxima statements are theoretically changeable in light of better understanding as they are not yet deemed infallible but are still highly regarded. Theologica certa, sententia communis and sententia probabilis statements are changeable and likely have undergone some refinenment over time. You need to consider the theological level/certainty of the doctrine in any discussion.
