It also means that we explore the layers of what has been revealed and discover layers that were always there, from the beginning, but we did not understand, missed, did not have the language to explain, explained incorrectly (the explanation was wrong, not the truth), or we explained it so narrowly or so broadly that we confused ourselves.
That’s why I always direct people three great thinkers on this question:
St. Bonaventure’s Theology of History In St. Bonaventure
Bl. John Henry Newman’s Development of Christian Doctrine
and
Pope Benedict XVI Introduction to Christianity
The each point you to the important fact that history unfolds for us what has been revealed from the beginning. It helps the theologian understand that dogma does not change, because truth is eternal. However, how much we understand, how we explain it, and how God leads us to understand is dynamic.
Bonaventure uses a wonderful example, the hypostatic union. He goes on to explain that the Apostles knew that Jesus was. truly Lord and truly human. They saw him die and they saw him three days later. In the paschal mystery the fullness of the Incarnation is revealed. Nothing new can be added. He is human and divine.
However, it took the Church 400 years to understand the hypostatic union and to define it clearly enough so that it could be included in the Creed, that’s why we have two editions of the Creed. The Apostles’ Creed is very him.
"He was born of the Virgin Mary
Crucified
Died
Rose again from the dead
We believe in the Holy Spirit"
The Nicene Creed is a much more developed doctrinal expose of what the Apostles believed, taught but did not fully understand, because they did not have the language.
"Conceived by the Holy Spirit
Died
Rose as predicted by the scriptures
the Holy Spirit is consubstantial with the Father and the Son"
Chalcedon and Nicea have a richer understanding of what the Apostles believed and handed down.
The dogma did not change, but the formulation of the dogma did change, because it gets into the details that were not understood before this time.
The theologian in Bonaventure, Newman and Ratzinger make a distinction between what is dogmatic and what is taught (doctrinal). We cannot teach that which is contrary to dogma or that which may not be contrary to dogma, but is not dogma either. It’s nonsense.
However, the “doctrina” or the teaching changes, while the essence remains eternal. Unfortunately, in the world of the non-theologian the terms dogma and doctrine have become interchangeable. In the world of theologians they mean two different things.
Dogma is the truth and doctrine is how you teach the truth. The latter can and does change as our understanding changes and the former is eternal
The three works that I cited above are three of the best works on theology of history or better said, how through history the Holy Spirit leads us into a deeper and clearer understanding of what has been revealed. There is no new revelation. There is certainly growth in our understand, which requires that we reformulate our explanations.
The best bet for anyone who really wants an expert’s response, not an amateur’s response to this very essential question, it to go to the masters on the Theology of History.
I certainly do not profess to be such a master. That’s a highly specialized area of theology that very few people go into, because it’s very difficult to study. It’s the theological equivalent to astrophysics. I took a few courses on it and it’s fascinating. Had I the brains for it, I would have gone that route.
