5. One indeed, etc. He had spoken before of scruples in the choice of meats; he now adds another example of difference, that is, as to days; and both these arose from Judaism. For as the Lord in his law made a difference between meats and pronounced some to be unclean, the use of which he prohibited, and as he had also appointed festal and solemn days and commanded them to be observed, the Jews, who had been brought up from their childhood in the doctrine of the law, would not lay aside that reverence for days which they had entertained from the beginning, and to which through life they had been accustomed; nor could they have dared to touch these meats from which they had so long abstained. That they were imbued with these notions, was an evidence of their weakness; they would have thought otherwise, had they possessed a certain and a clear knowledge of Christian liberty. But in abstaining from what they thought to be unlawful, they evidenced piety, as it would have been a proof of presumption and contempt, had they done anything contrary to the dictates of conscience.

Here then the Apostle applies the best rule, when he bids every one to be fully assured as to his own mind; by which he intimates that there ought to be in Christians such a care for obedience, that they do nothing, except what they think, or rather feel assured, is pleasing to God. ¹ And this ought to be thoroughly borne in mind, that it is the first principle of a right conduct, that men should be dependent on the will of God, and never allow themselves to move even a finger, while the mind is doubtful and vacillating; for it cannot be otherwise, but that rashness will soon pass over into obstinacy when we dare to proceed further than what we are persuaded is lawful for us. If any object and say, that infirmity is ever perplexing, and that hence such certainty as Paul requires cannot exist in the weak: to this the plain answer is, -- That such are to be pardoned, if they keep themselves within their own limits. For Paul's purpose was none other than to restrain undue liberty, by which it happens, that many thrust themselves, as it were, at random, into matters which are doubtful and undetermined. Hence Paul requires this to be adopted, -- that the will of God is to preside over all our actions.

6. He who regards a day, etc. Since Paul well knew that a respect for days proceeded from ignorance of Christ, it is not probable that such a corruption was altogether defended by him; and yet his words seem to imply, that he who regarded days committed no sin; for nothing but good can be accepted by God. Hence, that you may understand his purpose, it is necessary to distinguish between the notion, which any one may have entertained as to the observance of days, and the observance itself to which he felt himself bound. The notion was indeed superstitious, nor does Paul deny this; for he has already condemned it by calling it infirmity, and he will again condemn it still more plainly. Now, that he who was held fast by this superstition, dared not to violate the solemnity of a particular day; this was approved by God, because he dared not to do any thing with a doubtful conscience. What indeed could the Jew do, who had not yet made such progress, as to be delivered from scruples about days? He had the word of God, in which the keeping of days was commended; there was a necessity laid on him by the law; and its abrogation was not clearly seen by him. Nothing then remained, but that he, waiting for a fuller revelation, should keep himself within the limits of his own knowledge, and not to avail himself of the benefit of liberty, before he embraced it by faith. ²

The same also must be thought of him who refrained from unclean meats: for if he ate in a doubtful state of mind, it would not have been to receive any benefit, from God's hand, but to lay his own hand on forbidden things. Let him then use other things, which he thinks is allowed to him, and follow the measure of his knowledge: he will thus give thanks to God; which he could not do, except he was persuaded that he is fed by God's kindness. He is not then to be despised, as though he offended the Lord by this his temperance and pious timidity: and there is nothing unreasonable in the matter, if we say, that the modesty of the weak is approved by God, not on the ground of merit, but through indulgence.

But as he had before required an assurance of mind, so that no one ought rashly of his own will to do this or that, we ought to consider whether he is here exhorting rather than affirming; for the text would better flow in this strain, -- "Let a reason for what he does be clear to every one; as an account must be given before the celestial tribunal; for whether one eats meat or abstains, he ought in both instances to have regard to God." And doubtless there is nothing more fitted to restrain licentiousness in judging and to correct superstitions, than to be summoned before the tribunal of God: and hence Paul wisely sets the judge before all, to whose will they are to refer whatever they do. It is no objection that the sentence is affirmative; for he immediately subjoins, that no one lives or dies for himself; where he declares, not what men do, but commands what they ought to do.

Observe also what he says, -- that we then eat to the Lord, or abstain, when we give thanks. Hence, eating is impure, and abstinence is impure, without thanksgiving. It is only the name of God, when invoked, that sanctifies us and all we have.
