Titus 1:15

15To the pure all things indeed are pure He glances at one class of fabulous opinions; for the choice of the kinds of food, (such as was temporarily enjoined by Moses,) together with purifications and washings, were insisted on as being still necessary, and they even made holiness to consist almost wholly in these minute observances. How dangerous to the Church this was, we have already explained. First, a snare of bondage was laid on the consciences; and next, ignorant persons, bound by this superstition, had a veil drawn over their eyes, which hindered them from advancing in the pure knowledge of Christ. If any of the Gentiles refused to submit to this yoke, because he had not been accustomed to it, the Jews vehemently contended for it, as if it had been the chief article of religions. Not without good reason, therefore, does Paul firmly oppose such corrupters of the gospel. In this passage, indeed, he not only refutes their error, but wittily laughs at their folly, in laboring anxiously, any advantage, about abstaining from certain kinds of food and things of that nature

In the first clause of this verse he upholds Christian liberty, by asserting, that to believers nothing is unclean; but at the same time he indirectly censures the false apostles who set no value on inward purity, which alone is esteemed by God. He therefore rebukes their ignorance, in not understanding that Christians are pure without the ceremonies enjoined by the Law; and next he chastises their hypocrisy, in disregarding uprightness of heart, and occupying themselves with useless exercises. But as the subject now in hand is not the health of the body, but peace of conscience, he means nothing else than that the distinction of the kinds of food, which was in force under the Law, has now been abolished. For the same reason it is evident, that they do wrong, who impose religious scruples on consciences in this matter; for this is not a doctrine intended for a single age, but an eternal oracle of the Holy Spirit, which cannot lawfully be set aside by any new law.

Accordingly, this must be true till the end of the world, that there is no kind of food which is unlawful in the sight of God; and, therefore, this passage is fitly and appropriately quoted in opposition to the tyrannical law of the Pope, which forbids the eating of flesh on certain days. And yet I am not unacquainted with the sophistical arguments which they employ. They affirm, that they do not forbid the eating of flesh, because they allege that it is unclean, (for they acknowledge that all kinds of food are in themselves clean and pure,) but that abstinence from flesh is enjoined on another ground, that it has a tendency to tame the lust of the flesh; as if the Lord had forbidden to eat swine’s flesh, because he judged swine to be unclean. Even under the Law the fathers reckoned that everything which God created is in itself pure and clean; but they held that they were unclean for this reason, that the use of them was unlawful, because God had forbidden it. All things are, therefore, pronounced by the Apostle to be pure, with no other meaning than that the use of all things is free, as regards the conscience. Thus, if any law binds the consciences to any necessity of abstaining from certain kinds of food, it wickedly takes away from believers that liberty which God had given them.

But to the polluted and unbelieving nothing is pure. This is the second clause, in which he ridicules the vain and useless precautions of such instructors. He says that they gain nothing by guarding against uncleanness in certain kinds of food, because they cannot touch anything that is clean to them. Why so? Because they are “polluted,” and, therefore, by their only touching those things which were otherwise pure, they become “polluted.”

To the “polluted” he adds the “unbelieving,” (235) not as being a different class of persons; but the addition is made for the sake of explanation. Because there is no purity in the sight of God but that of faith, it follows that all unbelievers are unclean. By no laws or rules, therefore, will they obtain that cleanness which they desire to have; because, being themselves “polluted,” they will find nothing in the world that is clean to them. (236)

But their mind and conscience are polluted. He shows the fountain from which flows all the filth which is spread over the whole life of man; for, unless the heart be well purified, although men consider works to have great splendor, and a sweet smell, yet with God they will excite disgust by their abominable smell and by their filthiness.

“The Lord looketh on the heart,” (1 Samuel 16:7,)

and

“his eyes are on the truth.” (Jeremiah 5:3.)

Whence it arises, that those things which are lofty before men are abomination before God.

The mind denotes the understanding, and the conscience relates rather to the affections of the heart. But here two things ought to be observed; first, that man is esteemed by God, not on account of outward works, but on account of the sincere desire of the heart; and, secondly, that the filth of infidelity is so great, that it pollutes not only the man, but everything that he touches. On this subject let the reader consult Haggai 2:11. In like manner Paul teaches that

“all things are sanctified by the word,” (1 Timothy 4:5,)

because men use nothing in a pure manner till they receive it by faith from the hand of God.
