The false teaching was cloaked in Jewish legality, and the false teachers were probably of Jewish stock. Perhaps they were descendants of those Jews whom Antiochus, according to the testimony of Josephus, moved from the east into southern Phrygia, numbering two thousand families.
They may have brought eastern speculations from there. Mixing them there with Hellenic philosophizing, they glued together from all three a particular system of false teaching, adapting it also to Christianity.
From Jewish customs they retained, as is evident, only rules about eating and drinking, observance of annual, monthly, and weekly feasts, and, very probably, circumcision.
The Apostle had spoken above, as though in passing, about the inappropriateness of circumcision for Christians. Now he speaks directly against Jewish customs concerning foods and feasts.
"Let no one judge you." Let no one condemn you because you do not observe such and such Jewish customs. But what should we do, someone might ask? Should we fulfill them in order to avoid condemnation? No, not fulfill them, but not take such condemnations to heart or pay attention to them.
Let them condemn. Do not look at it. Probably, among their methods of persuasion, those wise men used irony or mockery. This can act powerfully and, when it meets a conviction that is not firm, can make it evaporate entirely.
The Apostle warns them: do not yield to the impression caused by condemnation. It is empty. "Do not submit," he says, "to those who condemn you" (Saint Chrysostom).
"Do not be at all carried away by those attempting to sow observances under the Law among you" (blessed Theodoret). "It is as though he praises them as estranged from Judaism" (blessed Theophylact), and by this encourages them to resist those who drag them into it.
"In food or in drink." In the Law it was precisely prescribed what to use as food and what not to use. The prohibition was based on the usefulness or harmfulness of foods in that climate.
At the same time, moral lessons were in view, arising visibly from the qualities of the forbidden animals and birds. But since those speculators went into falsehood, it is very probable that they wove into this some absurd divinations in the spirit of their false teaching.
The Law speaks only about foods. A rule concerning drink is laid down only for Nazirites. Therefore one may infer that those wise men came forward as permanent Nazirites and made the rules of Nazirite life obligatory for all.
The Essenes seemed to practice a permanent Nazirite way of life. Perhaps the Colossian wise men came from this sect.
"Or in respect of a feast," that is, some great annual feast: Passover, Pentecost, Tabernacles, and others. They could not observe these feasts fully. Because of the distance, they could not go to Jerusalem every year.
When they celebrated at home, they could not perform everything that belonged to the feast. Therefore the Apostle said, "in respect of." "He did not say, in the observance of Tabernacles, or Unleavened Bread, or Pentecost, but 'in respect of a feast.'
"For they did not dare to preserve everything. Even if they did preserve something, they did not keep them as feasts. He says 'in respect of,' showing that the greater part had already been abandoned, and that they did not retain all the former things" (Saint Chrysostom).
One may also infer that those speculators reconstructed everything belonging here according to their own way. They took only something from the former practice. This partial element was taken from the order of celebrating new moons and Sabbaths.
They could not observe everything related to these either. Nevertheless, even though such celebration, cut down and altered, was no longer fully Jewish, the Apostle does not want the Colossians to touch it.
So contrary is it to the spirit of Christianity. The Apostle is not turning them away from feasts in general, but from celebration on certain days in the spirit of Judaism or of the false teaching that circulated among the Colossians.
To have feasts and celebrate them is an inseparable part of faith, insofar as faith exists, whatever it may be. We are so constituted. All faiths have them, but each in its own spirit. Christianity also has its feasts, but in its own spirit.
