One of the great challenges as a Protestant is to know and understand how we came to be. The Reformation is our roots in history, but the Bible is our root in theology. Simply put, to be Protestant means you leave the man-made teachings of the Roman Catholic Church and look towards Scripture as your authority for faith and practice.
Why do I make this point when talking about the Early Church Fathers (ECF)? It is simple. Catholics tend to put an inordinate amount of weight and authority in the ECF. They do this to the point of elevating their writings to the level of Scripture. However, they will tell you that they do not do this. Yet, when shown their interpretation is incorrect Biblically, they will say, “But Origen said…” or “But Iraneus argued….” or “But Clement states…” and so on. When you simply say they are wrong, and point out the error, they will say that are we to know better than those that sat under the Apostles?
This, of course, is a logical fallacy. It is an appeal to authority. However, there is no authority there.
We do not hold that the ECF were infallible. There is nothing in Scripture to suggest that the ECF, or the church today, including the Pope, are infallible in any way (though the Catholics will try to argue that there is). So how are we to use the ECF?
The answer to this is not difficult. We should use the ECF as we use any other commentary. It is useful for study and instruction but must always be tested against the Scriptures. The Scriptures and Scriptures alone have the final say in all matters of faith and practice. The ECF did get things wrong, and often, they even contradicted each other. Scripture, on the other hand, has no contradictions. It is the perfect and holy words of God.
So while we should read the Fathers, we should not elevate their work to the level of Scripture.
