On the ethical side the tenet that the human body is utterly evil produced two opposite errors,--asceticism and antinomian sensuality. And both of these are aimed at in these Epistles. If the enlightenment of the soul is everything, and the body is utterly worthless, then this vile clog to the movement of the soul must be beaten under and crushed, in order that the higher nature may rise to higher things. The body must be denied all indulgence, in order that it may be starved into submission (iv. 3). On the other hand, if enlightenment is everything and the body is worthless, then every kind of experience, no matter how shameless, is of value, in order to enlarge knowledge. Nothing that a man can do can make his body more vile than it is by nature, and the soul of the enlightened is incapable of pollution. Gold still remains gold, however often it is plunged in the mire.
The words of the three verses taken as a text, look as if St. Paul was aiming at evil of this kind. These Judaizing Gnostics "desired to be teachers of the Law." They wished to enforce the Mosaic Law, or rather their fantastic interpretations of it, upon Christians. They insisted upon its excellence, and would not allow that it has been in many respects superseded. "We know quite well," says the Apostle, "and readily admit, that the Mosaic Law is an excellent thing; provided that those who undertake to expound it make a legitimate use of it. They must remember that, just as law in general is not made for those whose own good principles keep them in the right, so also the restrictions of the Mosaic Law are not meant for Christians who obey the Divine will in the free spirit of the Gospel." Legal restrictions are intended to control those who will not control themselves; in short, for the very men who by their strange doctrines are endeavouring to curtail the liberties of others. What they preach as "the Law" is really a code of their own, "commandments of men who turn away from the truth.... They profess that they know God; but by their works they deny Him, being abominable, and disobedient, and unto every good work reprobate" (Tit. i. 14, 16). In rehearsing the various kinds of sinners for whom law exists, and who are to be found (he hints) among these false teachers, he goes roughly through the Decalogue. The four commandments of the First Table are indicated in general and comprehensive terms; the first five commandments of the Second Table are taken one by one, flagrant violators being specified in each case. Thus the stealing of a human being in order to make him a slave, is mentioned as the most outrageous breach of the eighth commandment. The tenth commandment is not distinctly indicated, possibly because the breaches of it are not so easily detected. The overt acts of these men were quite sufficient to convict them of gross immorality, without enquiring as to their secret wishes and desires. In a word, the very persons who in their teaching were endeavouring to burden men with the ceremonial ordinances, which had been done away in Christ, were in their own lives violating the moral laws, to which Christ had given a new sanction. They tried to keep alive, in new and strange forms, what had been provisional and was now obsolete, while they trampled under foot what was eternal and Divine.
"If there be any other thing contrary to the sound doctrine." In these words St. Paul sums up all the forms of transgression not specified in his catalogue. The sound, healthy teaching of the Gospel is opposed to the morbid and corrupt teaching of the Gnostics, who are sickly in their speculations (vi. 4), and whose word is like an eating sore (2 Tim. ii. 17). Of course healthy teaching is also _health-giving_, and corrupt teaching is _corrupting_; but it is the primary and not the derived quality that is stated here. It is the healthiness of the doctrine in itself, and its freedom from what is diseased or distorted, that is insisted upon. Its wholesome character is a consequence of this.
