We can thus see why Paul, not wanting the grace of the Spirit given to us to grow cold, exhorts us, “Do not quench the Spirit.” The only way we can continue to be partakers of Christ is to cling until the end to the Holy Spirit, who was given to us at the beginning. Paul said, “Do not quench” not because the Spirit is under the power of men but because evil and unthankful men certainly do wish to quench the Spirit. Demonstrating their impurity, they drive the Spirit away by their unholy deeds.
Do not oppose either the interior gifts of the holy Spirit, which are his graces, nor his exterior gifts of prophecy. Take the regular precautions of prudence, that you be not deceived by those who pretend to be inspired; but when satisfied that the inspiration comes from heaven, do not despise it. Be like good bankers, take the good coin, and reject the counterfeit. (St. Cyril of Alexandria)
On this account Paul says, Quench not the Spirit, that is, the gift of grace, for it is his custom so to call the gift of the Spirit. But this an impure life extinguishes. For as any one, who has sprinkled both water and dust upon the light of our lamp, extinguishes it, and if he does not this, but only takes out the oil— so it is also with the gift of grace. For if you have cast over it earthly things, and the cares of fluctuating matters, you have quenched the Spirit. And if you have done none of these things, but a temptation coming from some other quarter has vehemently assailed it, as some wind, and if the light be not strong, and it has not much oil, or you have not closed the opening, or have not shut the door, all is undone. But what is the opening? As in the lamp, so is it also in us: it is the eye and the ear. Suffer not a violent blast of wickedness to fall upon these, since it would extinguish the lamp, but close them up with the fear of God. The mouth is the door. Shut it,...
As fire requires fuel, so grace requires our prompt response, that it may be ever fervent. “I put you in remembrance that you stir up the gift of God that is in you by the putting on of my hands,” that is, the grace of the Spirit, which you have received, for presiding over the church, for the working of miracles and for every service. For this grace it is in our power to kindle or extinguish. For this reason Paul elsewhere says, “Do not quench the Spirit.”
On this account Paul says, “Do not quench the Spirit,” that is, the gift of grace, for it is his custom so to call the gift of the Spirit. But an impure life extinguishes the gift of grace. For as anyone who has sprinkled both water and dust upon the light of our lamp extinguishes it…. So it is also with the gift of grace.
Learn from the apostle that we are the ones who grieve the Spirit, extinguishing him in our hearts. He says, “Do not quench the Spirit, do not despise prophecy”; and again, “Do not grieve the Holy Spirit, in whom you have been sealed for the day of redemption.” We introduce these testimonies not as if to suggest that every man who has been baptized and obtained grace is henceforth immutable and no longer in need of repentance, but to say that through baptism, according to Christ’s gift, the complete grace of God is granted to us for the fulfillment of the commandments. Henceforth each one who receives baptism mystically and yet does not fully perform the commandments, is activated by sin in proportion to their failure—the sin not of Adam but of the one who is negligent. On Baptism, Response
That is to say, do not grieve him by sin, otherwise his light will be quenched from your soul—a light which, when kindled within you, gives you the possession of a power that is beyond expression; and you will be able to contend “with principalities and powers,” and fight against the evil spirits under heaven, and reject all the world with its pleasures and pains. All are effected by the fervor of the Spirit within us. .
Now, from whom shall I expect (the fulfil-merit of) all this, except from Him whom I have heard give the promise thereof? What "spirit "does he forbid us to "quench "and what "prophesyings "to "despise? "
