Isaias 1:22

1. For the tradition of the elders themselves, which they pretended to observe from the law, was contrary to the law given by Moses. Wherefore also Esaias declares: “Thy dealers mix the wine with water,” showing that the elders were in the habit of mingling a watered tradition with the simple command of God; that is, they set up a spurious law, and one contrary to the [true] law; as also the Lord made plain, when He said to them, “Why do ye transgress the commandment of God, for the sake of your tradition?” For not only by actual transgression did they set the law of God at nought, mingling the wine with water; but they also set up their own law in opposition to it, which is termed, even to the present day, the pharisaical. …

Would to God that no “heresies had been ever necessary, in order that they which are approved may be made manifest!” We should then be never required to try our strength in contests about the soul with philosophers, those patriarchs of heretics, as they may be fairly called. The apostle, so far back as his own time, foresaw, indeed, that philosophy would do violent injury to the truth. This admonition about false philosophy he was induced to offer after he had been at Athens, had become acquainted with that loquacious city, and had there had a taste of its huckstering wiseacres and talkers. In like manner is the treatment of the soul according to the sophistical doctrines of men which “mix their wine with water.” Some of them deny the immortality of the soul; others affirm that it is immortal, and something more. …

VI . Now the bishop ought to know whose oblations he ought to receive, and whose he ought not. For he is to avoid corrupt dealers, and not receive their gifts. “For, a corrupt dealer shall not be justified from sin.” For of them it was that Isaiah reproached Israel, and said, “Thy corrupt dealers mingle wine with water.” He is also to avoid fornicators, for “thou shall not offer the hire of an harlot to the Lord.” He is also to avoid extortioners, and such as covet other men’s goods, and adulterers; for the sacrifices of such as these are abominable with God. Also those that oppress the widow and overbear the orphan, and fill prisons with the innocent, and abuse their own servants wickedly, I mean with stripes, and hunger, and hard service, nay, destroy whole cities; do thou, O bishop, avoid such as these, and their odious oblations. …

‘For even if we use great sounding words, yet we declared nothing to be our own that we achieved, but all Christ’s. For we will not imitate the false apostles; the men who say that most is of themselves.’ For this is “to corrupt,” when one adulterates the wine; when one sells for money what he ought to give freely. For he seems to me to be here both taunting them in respect to money, and again hinting at the very thing I have said, as that they mingle their own things with God’s; which is the charge Isaiah brings when he said, “Thy vintners mingle wine with water:” ( Is. i. 22 , LXX.) for even if this was said of wine, yet one would not err in expounding it of doctrine too. …

46. And who is sufficient for these things? For we are not as the many, able to corrupt the word of truth, and mix the wine, which maketh glad the heart of man, with water, mix, that is, our doctrine with what is common and cheap, and debased, and stale, and tasteless, in order to turn the adulteration to our profit, and accommodate ourselves to those who meet us, and curry favor with everyone, becoming ventriloquists and chatterers, who serve their own pleasures by words uttered from the earth, and sinking into the earth, and, to gain the special good will of the multitude, injuring in the highest degree, nay, ruining ourselves, and shedding the innocent blood of simpler souls, which will be required at our hands.
