The Holy Spirit created all things and the Scriptures are His

And to such a degree has the Holy Ghost made this the rule of His Scripture, that whenever anything is made out of anything, He mentions both the thing that is made and the thing of which it is made. “Let the earth,” says He, “bring forth grass, the herb yielding seed, and the fruit-tree yielding fruit after its kind, whose seed is in itself, after its kind.

…if the Holy Ghost took upon Himself so great a concern for our instruction, that we might know from what everything was produced, would He not in like manner have kept us well informed about both the heaven and the earth, by indicating to us what it was that He made them of, if their original consisted of any material substance, so that the more He seemed to have made them of nothing, the less in fact was there as yet made, from which He could appear to have made them?

Tertullian claims that belief in the soul must have come from the Jewish scriptures first

But, clearly, since the Scriptures of God, whether belonging to Christians or to Jews, into whose olive tree we have been grafted—are much more ancient than any secular literature, (or, let us only say, are of a somewhat earlier date, as we have shown in its proper place when proving their trustworthiness); if the soul have taken these utterances from writings at all, we must believe it has taken them from ours, and not from yours, its instruction coming more naturally from the earlier than the later works.

The unraveling onion of the Reformation criticism of tradition

Like many of the Protestant critics who followed him, Semler could claim to be following in the footsteps of Luther and the Reformation, and to be doing so with greater consistency than the political situation of the 16th century had permitted the first Protestant reformers themselves to do. The same kind of historical–critical scrutiny to which Luther and his fellow reformers had subjected to cherished traditions and doctrines of the medieval church, such as the claims of the Papacy or even the sacramental system, could and should be rolled back to the very first centuries of the history of the church. Even the first century, revered as “apostolic,” must not be beyond the reach of historical criticism.

The irony of pitting the Bible against the Church

Another aspect of the divine irony that we have seen repeatedly in the history of the use of the Bible within both Judaism and Christianity is that the Bible being used as a weapon against church and tradition had itself come from the arsenal of the church and had been preserved and protected by the tradition.

The Bible is not self authenticating

The very conflict over the biblical canon between the Protestant Reformers and the Council of Trent made it clear that even in a doctrine of sola Scriptura the authority of the Bible did not authenticate itself automatically (which would have required some kind of doctrine of repeated inspiration in each generation of the history of the church) but depended on recognition by tradition and by the church for acceptance.

Origen quotes the Deuterocanon in support of the Intercession of Saints

But these pray along with those who genuinely pray—not only the high priest but also the angels who “rejoice in heaven over one repenting sinner more than over ninety-nine righteous that need not repentance,” and also the souls of the saints already at rest. Two instances make this plain. The first is where Raphael offers their service to God for Tobit and Sarah. After both had prayed, the scripture says, “The prayer of both was heard before the presence of the great Raphael and he was sent to heal them both,” and Raphael himself, when explaining his angelic commission at God’s command to help them, says:

“Even now when you prayed, and Sarah your daughter-in-law, I brought the memorial of your prayer before the Holy One,” and shortly after, “I am Raphael, one of the Seven angels who present the prayers of saints and enter in before the glory of the Holy One. Thus, according to Raphael’s account at least, prayer with fasting and almsgiving and righteousness is a good thing.

The second instance is in the Books of the Maccabees where Jeremiah appears in exceeding “white haired glory” so that a wondrous and most majestic authority was about him, and stretches forth his right hand and delivers to Judas a golden sword, and there witnesses to him another saint already at rest saying, “This is he who prays much for the people and the sacred city, God’s prophet Jeremiah.” For it is absurd when knowledge, though manifested to the worthy through a mirror and in a riddle for the present, is then revealed face to face not to think that the like is true of all other excellences as well, that they who prepare in this life beforehand are made strictly perfect then.

Origen
On Prayer
Chapter VI

Not everything is found in Holy Scripture

If, for these and other such rules, you insist upon having positive Scripture injunction, you will find none. Tradition will be held forth to you as the originator of them, custom as their strengthener, and faith as their observer. That reason will support tradition, and custom, and faith, you will either yourself perceive, or learn from some one who has.

…This instances, therefore, will make it sufficiently plain that you can vindicate the keeping of even unwritten tradition established by custom; the proper witness for tradition when demonstrated by long-continued observance.

Tertullian
The Chaplet
Chapter IV

The four Gospels agree on essential matters and differ in details

Of the apostles, therefore, John and Matthew first instill faith into us; whilst of apostolic men, Luke and Mark renew it afterwards. These all start with the same principles of the faith, so far as relates to the one only God the Creator and His Christ, how that He was born of the Virgin, and came to fulfill the law and the prophets. Never mind if there does occur some variation in the order of their narratives, provided that there be agreement in the essential matter of the faith, in which there is disagreement with Marcion.

The heretics are refuted by tradition, without a battle over scriptural interpretation

Since this is the case, in order that the truth may be adjudged to belong to us, “as many as walk according to the rule,” which the church has handed down from the apostles, the apostles from Christ, and Christ from God, the reason of our position is clear, when it determines that heretics ought not to be allowed to challenge an appeal to the Scriptures, since we, without the Scriptures, prove that they have nothing to do with the Scriptures. For as they are heretics, they cannot be true Christians, because it is not from Christ that they get that which they pursue of their own mere choice, and from the pursuit incur and admit the name of heretics. Thus, not being Christians, they have acquired no right to the Christian Scriptures; and it may be very fairly said to them, “Who are you? When and whence did you come? As you are none of mine, what have you to do with that which is mine?

Indeed, Marcion, by what right do you hew my wood?  By whose permission, Valentinus, are you diverting the streams of my fountain? By what power, Apelles, are you removing my landmarks? This is my property. Why are you, the rest, sowing and feeding here at your own pleasure?  This (I say) is my property. I have long possessed it; I possessed it before you. I hold sure title-deeds from the original owners themselves, to whom the estate belonged.  I am the heir of the apostles.  Just as they carefully prepared their will and testament, and committed it to a trust, and adjured (the trustees to be faithful to their charge), even so do I hold it. As for you, they have, it is certain, always held you as disinherited, and rejected you as strangers—as enemies. But on what ground are heretics strangers and enemies to the apostles, if it be not from the difference of their teaching, which each individual of his own mere will has either advanced or received in opposition to the apostles?”
