Galatians 4:10

(Inburnt?) With what fires, prithee? The fires, I ween, which lead us to repeated contracting of nuptials and daily cooking of dinners! Thus, too, they affirm that we share with the Galatians the piercing rebuke (of the apostle), as "observers of days, and of months, and of years." Meantime they huff in our teeth the fact that Isaiah withal has authoritatively declared, "Not such a fast hath the Lord elected," that is, not abstinence from food, but the works of righteousness, which he there appends: and that the Lord Himself in the Gospel has given a compendious answer to every kind of scrupulousness in regard to food; "that not by such things as are introduced into the mouth is a man defiled, but by such as are produced out of the mouth; " while Himself withal was wont to eat and drink till He made Himself noted thus; "Behold, a gormandizer and a drinker: " (finally), that so, too, does the apostle teach that "food commendeth us not to God; since we neither abound if we eat, nor lack if we eat not.

Being, therefore, observers of "seasons" for these things, and of "days, and months, and years," we Galaticize.

He tells us himself clearly enough what he means by "elements," even the rudiments of the law: "Ye observe days, and months, and times, and years" -the sabbaths, I suppose, and "the preparations," and the fasts, and the "high days.

So that he may be seen to say this to Jews and about Jews—that is, to the Galatians, who combine the Jews’ way of life with theirs—he adds, “You observe days and months and seasons and years.” … For it is one thing to observe days, as for example to rest on the sabbath, another to observe months, as for example to observe new moons, … another to observe years, another again [to observe] seasons such as fasting, the Passover, the feast of unleavened bread and other things of this kind.

The observers of days are those who say, for example, “Tomorrow there must be no setting out on a journey.” … The observers of months are those who watch the course of the moon, saying, for example, “Contracts must not be sealed in the seventh month.” … Seasons are observed when people say, “Today is the first day of spring, it is a festival and after tomorrow is the feast of Vulcan.” … People pay respect to the year when they say, “The first day of January is the new year,” as though a year were not completed every day.… For if God is loved with the whole heart, there ought not to be any dread or suspicion of these phenomena so long as he is near.

For they ought to reflect, that as a season has been fixed suitable for planting and sowing, so days have been appointed as appropriate for cohabitation, which are carefully to be observed. Accordingly some one well instructed in the doctrines taught by Moses, finding fault with the people for their sins, called them sons of the new moons and the sabbaths. Yet in the beginning of the world men lived long, and had no diseases. But when through carelessness they neglected the observation of the proper times, then the sons in succession cohabiting through ignorance at times when they ought not, place their children under innumerable afflictions.

Hence is plain that their teachers were preaching to them not only circumcision, but also the feast-days and new-moons.

(Verses 10, 11.) Observing days, and months, and seasons, and years, I fear for you, lest perhaps I have labored in vain among you. Whoever does not worship the Father in spirit and truth, does not know the Sabbath rest that is reserved for the holy ones, about which God speaks: 'If they shall enter into my rest' (Psalm 94:11); and does not remember those times, of which it is written: 'Remember the days of old' (Isaiah 46:9). And elsewhere: 'I remembered the days of old, and I had in mind the eternal years' (Psalm 76:6). He observes the Jewish days, and months, and seasons, and years. Days, such as the Sabbath, the new moon, and from the tenth day of the first month until the fourteenth, when the literal lamb of the sacrifice is reserved, and from the fourteenth until the twenty-first of the same month, when unleavened bread is eaten, not in sincerity and truth, but in the old leaven of malice and wickedness of the Pharisees. He also celebrates the seven weeks, which the Jewish custom calculates after the unleavened bread, the days of the Israelite Pentecost. And also the sound of trumpets on the seventh day of the first month. Similarly, on the tenth day of the same month, they observe a day of expiation and fasting, as well as the custom of setting up booths, in the Jewish manner. They also observe the months, those who observe the first and seventh month, not understanding the mystery of truth. They also honor the seasons, who come to Jerusalem three times a year, thinking they fulfill the Lord's command, saying: Three times in the year you shall hold a feast for me, the feast of unleavened bread and the feast of the first fruits of the harvest, and the feast of the ingathering at the end of the year (Exodus 23:14ff.). And elsewhere: In three times of the year your male shall appear in the sight of the Lord your God (Ibid. XVII). But what he says, 'and years,' I think is said concerning the seventh year of remission, and the fiftieth, which they call Jubilee. The Apostle explains this passage more fully in his letter to the Colossians, saying: Therefore let no one pass judgment on you in questions of food and drink or with regard to a festival or a new moon or a Sabbath. These are a shadow of the things to come (Coloss. II, 16). He placed a part of the festival to be celebrated for the distinction of perpetual festivity, so that we have not a brief, and, as it were, a certain portion of the whole body, but the entire space of our life in perpetual celebration in Christ. And in order to connect the later with the earlier, he immediately adds and says: If you have died with Christ from the elements of this world, why do you still decree as if living in this world? You shall not touch, nor taste, nor handle, which are all things destined to perish with the using, according to the commandments and doctrines of men. Let no one judge you in matters of observing days, months, seasons, and years. We also incur a similar crime by observing the fourth day of the Sabbath, and Preparation Day, and the Lord's Day, and the fasting of Lent, and the celebration of Easter, and the joy of Pentecost, and the different times established in honor of the martyrs according to the custom of each region. To which, one who responds simply will say: the Jewish observance days are not the same as ours. For we do not celebrate the Passover of unleavened bread, but of the resurrection and the cross. Nor do we count seven weeks in Pentecost according to the custom of Israel, but we honor the coming of the Holy Spirit. And so that the disorderly gathering of the people would not diminish faith in Christ, certain days were established so that we all would come together as one. Not so much that day on which we meet is more famous, but that on whichever day we should meet, mutual joy should arise out of sight (or even out of aspect). However, whoever attempts to answer the opposite question more sharply affirms that all days are equal, not only the Friday on which Christ was crucified and the Sunday on which He rose, but that every day is holy and every day we partake of the flesh of the Lord. However, fasts and gatherings among days have been established by wise men for those who are more occupied with the world than with God, and they cannot, no, they do not want to gather together in the Church during the whole time of their lives, and to offer the sacrifice of their prayers to God before human actions. For how many people are there who at least practice these few things that have been established, either the times of prayer or the times of fasting? Therefore, just as it is permissible for us to fast at all times, or to pray at all times, and to continuously celebrate the Lord's day with the reception of the Lord's body, so it is not permissible for the Jews to sacrifice a lamb at all times, to celebrate Pentecost, to set up tabernacles, and to fast daily. However, with caution and moderation, he balanced the authority of the Apostle and the gentleness of the holy man, saying: I fear lest I have labored in vain among you. For if he had wanted to condemn them abruptly, he would certainly have said: I fear you: for I have labored without cause in you. But now, seeing that they have zeal for God, but not according to knowledge, he did not entirely despair of their salvation, who had been deceived by a godly error, nor did he leave them blameless, lest he give occasion both to them to persist in error, and to others to make a similar mistake. I fear you, he said, for what you are. I fear for you. The teacher labors without cause, when he himself challenges the students to greater things, and they, having fallen back, return to lesser and lower things.

By “years” I think he means the seventh year of release, and the fiftieth, which they call the jubilee.
