29. No filthy speech. He first forbids believers to use any filthy language, including under this name all those expressions which are wont to be employed for the purpose of inflaming lust. Not satisfied with the removal of the vice, he enjoins them to frame their discourse for edification. In another Epistle he says, “Let your speech be seasoned with salt.” (Colossians 4:6.) Here a different phrase is employed, if any (speech) be good to the use of edifying, which means simply, if it be useful. The genitive, of use, may no doubt be viewed, according to the Hebrew idiom, as put for an adjective, so that for the edification of use (πρὸς οἰκοδομὴν τὢς χρείας) may mean for useful edification; but when I consider how frequently, and in how extensive a meaning, the metaphor of edifying occurs in Paul’s writings, I prefer the former exposition. The edification of use will thus mean the progress of our edification, for to edify is to carry forward. To explain the manner in which this is done, he adds, that it may impart grace to the hearers, meaning by the word grace, comfort, advice, and everything that aids the salvation of the soul.

30. And grieve not. As the Holy Spirit dwells in us, to him every part of our soul and of our body ought to be devoted. But if we give ourselves up to aught that is impure, we may be said to drive him away from making his abode with us; and, to express this still more familiarly, human affections, such as joy and grief, are ascribed to the Holy Spirit. ¹⁵¹¹⁵¹     “According to our view, the verse is a summation of the argument — the climax of appeal. If Christians shall persist in falsehood and deviation from the truth — if they shall indulge in fitful rage, or cherish sullen and malignant dislikes — if they shall be characterized by dishonesty, or insipid and corrupt language, then do they grieve the Holy Spirit of God; for all this perverse insubordination is in utter antagonism to the essence and operations of Him who is the Spirit of truth; and inspires the love of it; who assumed, as a fitting symbol, the form of a dove, and creates meekness and forbearance; and who, as the Spirit of holiness, leads to the appreciation of all that is just in action, noble in sentiment, and healthful and edifying in speech.” — Eadie. Endeavour that the Holy Spirit may dwell cheerfully with you, as in a pleasant and joyful dwelling, and give him no occasion for grief. Some take a different view of it, that we grieve the Holy Spirit in others, when we offend by filthy language, or, in any other way, godly brethren, who are led by the Spirit of God. (Romans 8:14.) Whatever is contrary to godliness is not only disrelished by godly ears, but is no sooner heard than it produces in them deep grief and pain. But that Paul’s meaning was different appears from what follows.

By whom ye are sealed. As God has sealed us by his Spirit, we grieve him when we do not follow his guidance, but pollute ourselves by wicked passions. No language can adequately express this solemn truth, that the Holy Spirit rejoices and is glad on our account, when we are obedient to him in all things, and neither think nor speak anything, but what is pure and holy; and, on the other hand, is grieved, when we admit anything into our minds that is unworthy of our calling. Now, let any man reflect what shocking wickedness there must be in grieving the Holy Spirit to such a degree as to compel him to withdraw from us. The same mode of speaking is used by the prophet Isaiah, but in a different sense; for he merely says, that they “vexed his Holy Spirit,” (Isaiah 63:10.) in the same sense in which we are accustomed to speak of vexing the mind of a man. By whom ye are sealed. The Spirit of God is the seal, by which we are distinguished from the wicked, and which is impressed on our hearts as a sure evidence of adoption.

Unto the day of redemption, — that is, till God conduct us into the possession of the promised inheritance. That day is usually called the day of redemption, because we shall then be at length delivered out of all our afflictions. It is unnecessary to make any observations on this phrase, in addition to what have already been made in expounding Romans 8:23, and 1 Corinthians 1:30. In this passage, the word sealed may have a different meaning from that which it usually bears, — that God has impressed his Spirit as his mark upon us, that he may recognize as his children those whom he perceives to bear that mark.

31. Let all bitterness. He again condemns anger; but, on the present occasion, views in connection with it those offenses by which it is usually accompanied, such as noisy disputes and reproaches. Between wrath and anger (Θυμὸν καὶ ὀργὴν) there is little difference, except that the former denotes the power, and the latter the act; but here, the only difference is, that anger is a more sudden attack. The correction of all the rest will be greatly aided by the removal of malice. By this term he expresses that depravity of mind which is opposed to humanity and justice, and which is usually called malignity.
