The tradition that originates from the apostles and is “preserved succession of presbyters in the Churches” is not some separate set of teaching distinct from scripture, but the living witness of what the scriptures teach in the local churches. Irenaeus point the Gnostics to the scriptures and they reject it. He then points to the visible doctrine of the church (which is identical to scripture) and they reject it. Here we see that for Irenaeus, Scripture and tradition are one and the same in that which they teach (as he expounds similarly in other parts of Against Heresies). The entire Gnostic system falls apart without their reliance on extra biblical dogma.
You’ve made some excellent points in your post, and I agree with much of what you said. For instance, I would agree that “Sacred Tradition” (at least for the most part) is really the correct interpretation of Scripture itself, not so much “extra-biblical” doctrines. Tertullian spoke of “the rule of faith” as the guide to interpreting Scripture, and I agree with him.
My main point in this discussion is not to try to argue for doctrines which are not contained in Scripture, but rather to maintain that we must find the Right Interpretation only in the Life of the Church.
We all, whether we like it or not, look at the Bible through a set of glasses, through our own presuppositions. They usually come from our culture, our upbringing, our own studies, and our personality, and having them is unavoidable. This is neither a good nor a bad thing: this just is a fact.
Now, since the NT is not a “systematic theology handbook” but rather a collection of epistles and histories written to certain groups for certain reasons at certain times, many things are not as clear to us (living 2000 years later) as we would like. Therefore, even though the Bible contains all the essential doctrines, there is a huge chance that our set of glasses will have become foggy and cracked over the centuries, making it hard for us to see the Bible in the way that it was originally written. That is why, in my opinion, we need to be very careful to fix our glasses so that we can read the Scriptures the way God intended.
Many of the early heretics used Scripture quite a bit also, making their heresies very difficult to fight. That is why the Early Fathers stressed so much the importance of having the right set of presuppositions when men looked at the Bible: for without these, one could “prove” almost anything. There were huge heretical groups in the early Church that twisted Scripture without end, because many things in the Bible are difficult to comprehend.
As Peter said, of Paul’s writings, “…his epistles…in which are some things hard to be understood, which they that are unlearned and unstable wrest, as they do also the other scriptures, unto their own destruction.” (2 Peter 3:16)
And Paul himself, showing the necessity of having both the true written Word and the correct interpretations, “Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle.” (2 Thess. 2:15)
Today, too many of our glasses are faulty—too many of our presuppositions are in error. Heresy after heresy arises and claims support from the Bible (“believers’ baptism”, “unitarianism”, “mere symbolic eucharist”, etc) . We say that their “proofs” are pish-posh, and they are, but why should they be wrong and we be right? If the Church as a whole is not in some sense infallible, how can we have the correct interpretation of the Bible? No, in my opinion, it is quite obvious that the right presuppositions are absolutely necessary, and it seems to me that the ECF argued that these “glasses” were only to be found in the Apostolic Churches.
After all, didn’t Christ promise that, “I will build my Church, and the gates of hell shall not prevail against it”?
Thank you for these discussions! I am just trying to find the truth in these issues. I appreciate your dialogue.
