Barclay Daily Study Bible (NT)
Titus 1:13-16
For that very reason correct them with severity, that they may grow healthy in the faith and not pay attention to Jewish fables and to rules and regulations made by men who persist in turning their backs on the truth.
"To the pure all things are pure."
But to those who are defiled and who do not believe, nothing is pure, because their mind and conscience are defiled. They profess to know God, but they deny their profession by their deeds, because they are repulsive and disobedient and useless for any good work.
The great characteristic of the Jewish faith was its thousands of rules and regulations. This, that and the next thing were branded as unclean; this, that and the next food were held to be tabu. When Judaism and Gnosticism joined hands even the body became unclean and the natural instincts of the body were held to be evil. The inevitable result was that long lists of sins were constantly being created. It became a sin to touch this or that; it became a sin to eat this or that food; it even became a sin to marry and to beget children. Things which were either good in themselves or quite natural became defiled.
So Paul strikes out the great principle--To the pure all things are pure. He had already said that even more definitely in Romans 14:20 when, to those who were constantly involved in questions about clean and unclean foods, he said: "All things are pure." It may well be that this phrase is not only a proverb but an actual saying of Jesus. When Jesus was speaking about these countless Jewish rules and regulations, he said: "There is nothing outside a man which by going into him can defile him; but the things which come out of a man are what defile him" (Mark 7:15).
It is a man's heart which makes all the difference. If he is pure in heart, all things are pure to him. If he is unclean in heart, then he makes unclean everything he thinks about or speaks about or touches. This was a principle which the great classical writers had often stated. "Unless the vessel is pure, said Horace, "everything you pour into it grows bitter." Seneca said: "Just as a diseased stomach alters the food which it receives, so the darkened mind turns everything you commit to it to its own burden and ruin. Nothing can come to evil men which is of any good to them, nay nothing can come to them which does not actually harm them. They change whatever touches them into their own nature. And even things which would be of profit to others become pernicious to them." The man with a dirty mind makes all things dirty. He can take the loveliest things and cover them with smut. But the man whose mind is pure finds all things pure.
It is said of these men that both their mind and conscience are defiled. A man comes to his decisions and forms his conclusions by using two faculties. He uses intellect to think things out; he uses conscience to listen to the voice of God. But if his intellect is warped in such a way that it can see the unclean thing anywhere, and if his conscience is darkened and numbed by his continual consent to evil, he can take no good decision at all.
A man must keep the white shield of his innocence unstained. If he lets impurity infect his mind, he sees all things through a mist of uncleanness. His mind soils every thought that enters into it; his imagination turns to lust every picture which it forms; he misinterprets every motive; he gives a double meaning to every statement. To escape that uncleanness we must walk in the cleansing presence of Jesus Christ.
THE UGLY AND THE USELESS LIFE (Titus 1:13-16 continued)
When a man gets into this state of impurity, he may know God intellectually but his life is a denial of that knowledge. Three things are singled out here about such a man.
(i) He is repulsive. The word (bdeluktos, G947) is the word particularly used of heathen idols and images. It is the word from which the noun bdelugma (G946), an abomination, comes. There is something repulsive about a man with an obscene mind, who makes sniggering jests and is a master of the unclean innuendo.
(ii) He is disobedient. Such a man cannot obey the will of God. His conscience is darkened. He has made himself such that he can hardly hear the voice of God, let alone obey it. A man like that cannot be anything else but an evil influence and is therefore unfit to be an instrument in the hand of God.
(iii) That is just another way of saying that he has become useless to God and to his fellow-men. The word used for useless (adokimos, G96) is interesting. It is used to describe a counterfeit coin which is below standard weight. It is used to describe a cowardly soldier who fails in the testing hour of battle. It is used of a rejected candidate for office, a man whom the citizens regarded as useless. It is used of a stone which the builders rejected. (If a stone had a flaw in it, it was marked with a capital A, for adokimos (G96), and left aside, as being unfit to have any place in the building.) The ultimate test of life is usefulness, and the man whose influence is ever towards that which is unclean is of no use to God or to his fellow-men. Instead of helping God's work in the world, he hinders it; and uselessness always invites disaster.
