Sound speech, unblamable [1] "Sound speech" relates (in my opinion) to ordinary life and familiar conversation; for it would be absurd to interpret it as relating to public instruction, since he only wishes that Titus, both in his actions and in his words, shall lead a life that agrees with his preaching. He therefore enjoins that his words shall be pure and free from all corruption. Unblamable may apply either to the words or the person of Titus. I prefer the latter view, that the other nouns in the accusative case (which the Greek syntax easily allows) may depend upon it in this sense -- "that thou mayest shew thyself unblamable in gravity, in integrity, and in sound words." That the adversary may be ashamed. Although a Christian man ought to look at other objects, yet this must not be neglected, to shut the mouth of wicked men, as we are everywhere taught that we should give no occasion for slander. Everything that they can seize on as improper in our conduct is maliciously turned against Christ and his doctrine. The consequence is, that, through our fault, the sacred name of God is exposed to insult. Accordingly, the more we perceive that we are keenly observed by enemies, let us be the more attentive to guard against their calumnies, and thus let their malignity strengthen in us the desire of doing well.

Footnotes

1 - "Irreprehensible, ou qu'on ne puisse condemner." -- "Unblamable, or that cannot be condemned."

Sound speech - Notes, 1-Timothy 1:10. He was to use language that would be spiritually "healthful" (ὑγιῆ hugiē); that is, true, pure, uncorrupted. - This word, and its correlatives, is used in this sense, in the New Testament, only by the apostle Paul. It is commonly applied to the body, meaning that which is healthful, or whole; see Luke 5:31; Luke 6:10; Luke 7:10; Luke 15:27; Matthew 12:13; Matthew 15:31; Mark 3:5; Mark 5:34; John 5:4, John 5:6,John 5:9, John 5:11, John 5:14-15; John 7:23; Acts 4:10; 3-John 1:2. For Paul's use of the word see 1-Timothy 1:10; 1-Timothy 6:3; 2-Timothy 1:13;2-Timothy 4:3; Titus 1:9, Titus 1:13; Titus 2:1-2, Titus 2:8. It does not elsewhere occur.
That cannot be condemned - Such as cannot be shown to be weak, or unsound; such that no one could find fault with it, or such as an adversary could not take hold of and blame. This direction would imply purity and seriousness of language, solidity of argument, and truth in the doctrines which he maintained.
That he that is of the contrary part may be ashamed - Ashamed that he has opposed such views.

Sound speech - Λογον ὑγιη· Sound or healing doctrine. Human nature is in a state of disease; and the doctrine of the Gospel is calculated to remove the disease, and restore all to perfect health and soundness. All false doctrines leave men under the influence of this spiritual disease; the unadulterated doctrine of the Gospel alone can heal men.
He that is of the contrary part - Whether this may refer to the Judaizing teachers in general, or to some one who might, by his false doctrine, have been disturbing the peace of the Churches in Crete, we cannot tell.
Having no evil thing to say of you - Against a person who is sound in his doctrine, and holy in his life, no evil can be justly alleged. He who reports evil of such a person must be confounded when brought to the test. Instead of περι ὑμων, of You, περι ἡμων, of Us, is the reading of CDEFG, and about forty others; with both the Syriac, all the Arabic, Slavonic, Vulgate, Itala, and several of the primitive fathers. This reading makes a better sense, and is undoubtedly genuine.

Sound speech that cannot be condemned,.... In the public ministry, the wholesome words of our Lord Jesus should be used, and the doctrines of the Gospel be expressed, as near as can be, in the words which the Holy Ghost teacheth, and not in the enticing words of man's wisdom; such speech or language should be chosen, that is plain, easy, and acceptable, and conveys just ideas of things; and which being agreeable to the Scriptures of truth, and the analogy of faith, cannot be justly found fault with: or this may refer to private conversation, in which no rotten speech, or corrupt communication should proceed out of the mouth; nothing but what is pure, sound, graceful, and edifying; no filthiness, nor foolish talking and jesting, which are not convenient, and are rightly condemned.
That he that is of the contrary part may be ashamed: that is, that he who is on the other side of the question, who opposes the truths of the Gospel, and is an adversary to them; whether he be an Heathen philosopher, or a Jewish Rabbi, or a judaizing teacher, or an heretical man, under the Christian name, may be put to shame and confusion; partly on account of that uncorruptness in doctrine and conversation, which he observes in the true and faithful ministers of the word, and is wanting in himself; and so being convinced, may be converted and brought to repentance, and to the acknowledgment of the truth; and partly on the account of the false charges and accusations brought by him against such:
having no evil thing to say of you; whether with respect to doctrine or practice. The Vulgate Latin version, and all the Oriental versions, read "us", instead of "you". The whole body is reproached for the sake of one or more.

speech--discourse in public and private ministrations.
he that is of the contrary part--the adversary (Titus 1:9; 2-Timothy 2:25), whether he be heathen or Jew.
may be ashamed--put to confusion by the power of truth and innocence (compare Titus 2:5, Titus 2:10; 1-Timothy 5:14; 1-Timothy 6:1).
no evil thing--in our acts, or demeanor.
of you--So one of the oldest manuscripts. Other very old manuscripts read, "of US," Christians.

Wholesome speech - In private conversation.
