Proverbs 22:28

Nonetheless, it is clear that many examples, which we never read in those Scriptures that we deem canonical but nonetheless are found in the apocryphal books and are shown clearly to have been taken from them, have been brought forth and inserted into the New Testament either by the apostles or the Evangelists. But we must not give credence to the apocryphal books even in this way, for the eternal boundaries, which our fathers erected, must not be moved. It could be that the apostles or the Evangelists, filled with the Holy Spirit, knew what had to be taken from those writings and what had to be refuted. But it is not for us to presume some such ability without danger, when we do not have such abundance of the Spirit.

The one who moves the boundaries of piety demonstrates either superstition or impiety. And the one who moves the boundaries of courage changes it into either audacity or cowardice. In the same manner, this applies to other virtues as well as to dogmas and other …

I cannot help wondering about such madness in certain people, the dreadful impiety of their blinded minds, their insatiable lust for error that they are not content with the traditional rule of faith as once and for all received from antiquity but are driven to …

Consider whether it would not be well to remember the words, "You shall not remove the ancient landmarks which your fathers have set." Nor do I say this because I hesitate to examine the Jewish Scriptures, comparing them with ours and noticing their differences. This, if it is not arrogant to say it, I have already to a great extent done to the best of my ability, laboring hard to get at the meaning in all the editions and various readings. I paid particular attention to the Septuagint translation, lest I might be found to accredit any forgery to the churches which are under heaven and give an occasion to those who seek such a pretext for gratifying their desire to slander prominent persons and to bring forth some accusation against those who are outstanding in our fellowship. And I make it my endeavor not to be ignorant of their various readings, so that in my controversies with the Jews I may not quote to them what is not found in their copies and that I may make some use of what they accept, even if it is not found in our Scriptures. For if we are so prepared for them in our discussions, they will not, as is their manner, scornfully laugh at Gentile believers on the grounds that we do not know the true readings recorded in their texts.

We reject all the doctrines introduced recently either through letters or through pamphlets as confusing the common people, since we are content with the ancient legislation of the fathers and obey the one who said, "Remove not the ancient landmarks which your fathers set up."
