When it comes to Christian doctrine the word “alone” is a very heavy word; for it comes with the burden of proving an absolute statement. Words matter—especially divinely revealed words; and correct interpretation of those words matter most of all.

We have to be especially careful with biblical phrases or passages that we hear and pray often. These can become so cliché that we fail to think about what they really mean and glaze over them without thinking about them. Remember: we are to love God with all our mind (Lk 10:27) and therefore we should never stop allowing the written Word of God to penetrate deeper into our intellect, the site of understanding. As Frank Sheed often reminded his readers, every new thing we learn about God is a new thing to love about God.

Furthermore, grasping the true teaching of Christ and the apostles aids us in our own growth in holiness and assists us in becoming the most effective evangelists we can be. St. Paul writes:

“Take heed unto thyself, and unto the doctrine; continue in them: for in doing this thou shalt both save thyself, and them that hear thee.” (1 Tim 4:16, KJV)

So is the Bible the Word of God? Yes.

Is the Bible alone the Word of God? Not according to the Bible.

For one, Jesus himself is the Word of God made flesh (Jn 1:1). But the Scriptures also reveal God’s Word to be something both spoken and written, something passed on by word of mouth and by letter (see 2 Thess 2:15).

All Christians can agree that the Bible is the inspired Word of God; for the Scriptures are theopneustos (God-breathed) according to Paul (2 Tim 3:16). But as I’ve mentioned above, God’s Word does not come to us merely by the Bible alone.

Sometimes the divine word travels directly from God’s mouth to man’s ear, such as it did to Abram in the Book of Genesis:

“After these things the word of the Lord came to Abram in a vision, “Fear not, Abram, I am your shield; your reward shall be very great.” (Gen 15:1)

These words are in the Scriptures now but at the time they were not; instead God’s holy Word was spoken directly to Abram in a vision.

The risen Christ appears to St. Paul and speaks to him after his conversion; but there is no direct transcript of this encounter between Paul and the Lord in the Scriptures. Surely, however, the words spoken by Christ directly to Paul can be considered “God-breathed.” Consider also when God speaks to Jesus—his beloved Son in whom he is well-pleased—at his baptism in the Jordan (Mt 3:17; Mk 1:11).

Here’s what I’m getting at: God’s inerrant Word comes to man in different ways than merely in writing. That the Bible is the sole rule of faith was never the view of the early Christians for, just like St. Paul and the apostles, the early Church writers held that tradition was to be revered and upheld for the sake of orthodoxy (or correct belief).

St. Ireneaus, and a disciple of Polycarp who was a disciple of John the apostle, affirmed tradition on many occasions—especially when addressing the heresies of his time. He writes:

“With this church, because of its superior origin, all churches must agree—that is, all the faithful in the whole world—and it is in her that the faithful everywhere have maintained the apostolic tradition.” (Against Heresies, 3:3:1–2)

Now let’s get this straight: when Jesus gets after the Pharisees for their “traditions of men” he is not condemning all traditions; he is condemning religious traditions that directly contradict the Word of God and the Christian way of love.

Apostolic tradition is a whole different ball game.

Protestants might be tempted to respond by saying, “Fine! But what Ireneaus means by “apostolic tradition” is the Scriptures.” But that’s a groundless assertion. No early Church writer ever affirmed this notion of sola scriptura. No passage in the Bible affirms that only the Bible is to be considered apostolic tradition (in fact, the Bible directly contradicts this as you’ll see). And finally, most of the early Christians had no access to the Gospels and epistles of the apostles (or copies of them), and the New Testament Scriptures were not even formally determined to be inspired until the fourth century. The gospel of Jesus Christ was primarily communicated to the earliest Christians by preaching!

Often Catholics are criticized by Protestants because they put sacred tradition on the same footing as sacred Scripture. Catholics assert that Scripture and tradition “flow from the same divine wellspring.” But this insight into the status of tradition has its roots in the Bible. In fact, tradition is something that comes to man from God in both written and oral form—the Bible itself is a tradition, for its contents are not declared in Scripture but rather have been discerned by the Church itself with the inspiration and guidance of the Holy Spirit. It is an interesting (and often overlooked fact) that both Catholics and Protestants put their trust in the discernment of the Catholic Church in this matter of the “inspired” contents of the Bible.

St. Paul explicitly refers to oral and written tradition in his second letter to the Thessalonians:

“So then, brethren, stand firm and hold to the traditions which you were taught by us, either by word of mouth or by letter.” (2 Thess 2:15)

And in his first letter to the Thessalonians, Paul refers to the word of God as something passed on by word of mouth (and not just by letter):

“And we also thank God constantly for this, that when you received the word of God which you heard from us, you accepted it not as the word of men but as what it really is, the word of God, which is at work in you believers.” (1 Thess 2:13)

And HERE Paul refers to the oral tradition passed on as the Word of God. Similarly in 1 Peter, apostolic preaching is referred to as inspired by God:

“‘[T]he word of the Lord abides for ever.’

That word is the good news which was preached to you.” (1 Pet 1:25)

Again, the point is that God’s inerrant Word (his divine and errorless revelation) comes to man in several ways and this is evident in the Bible, especially through the writings of St. Paul.

The Word of God is always perfect and without error; but it is not always in writing.

God can speak his Word directly to man interiorly. He can speak through visions or miraculous encounters. God speaks to man through the Scriptures. And God speaks to man through the sacred oral tradition of the Church (the foremost example being the “tradition of the New Testament books.”

G.K Chesterton saw the practicality of tradition, both in religious belief and in society. He wrote famously:

“Tradition means giving a vote to most obscure of all classes, our ancestors. It is the democracy of the dead.”

In other words, the voices of those who have died before us matter; and especially the voices of the apostles. Christians thus have a duty to interpret the Scriptures in unison with the tradition of the apostles, for they have looked him in the eyes and heard him speak; they have watched God move among man. It was the apostles, and them alone, that could say:

“That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon and touched with our hands, concerning the word of life.” (1 Jn 1:1)
