Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ. Beware lest any man spoil you - The word συλαγωγων, from συλη, prey, and αγειν, to lead or carry away, signifies to rob, or spoil of their goods, as if by violence or rapine. Their goods were the salvation they had received from Christ; and both the Gentile and Jewish teachers endeavored to deprive them of these, by perverting their minds, and leading them off from the truths of Christianity.
Philosophy and vain deceit - Or, the vain or empty deceit of philosophy; such philosophizing as the Jewish and Gentile teachers used. As the term philosophy stood in high repute among the Gentiles, the Jews of this time affected it; and both Philo and Josephus use the word to express the whole of the Mosaic institutions. So the former: Ὁι κατα Μωσην φιλοσοφουντες· "Those who embraced the philosophy of Moses;" Phil., De Nomin. Mutand. And the latter; Τρια παρα Ιουδαιοις ειδη φιλοσοφειται· "There are three systems of philosophy among the Jews," (Bell. Jud., lib. ii. cap 8, sec. 2), meaning the Pharisees, Sadducees, and Essenes, as immediately follows. The Jewish philosophy, such as is found in the Cabala, Midrashim, and other works, deserves the character of vain deceit, in the fullest sense and meaning of the words. The inspired writers excepted, the Jews have ever been the most puerile, absurd, and ridiculous reasoners in the world. Even Rabbi Maymon, or Maimonides, the most intelligent of them all, is often in his master piece (the Moreh Nevochim, the Teacher of the Perplexed) most deplorably empty and vain.
After the rudiments of the world - According to the doctrine of the Jewish teachers; or, according to the Mosaic institutions, as explained and glossed by the scribes, Pharisees, and rabbins in general. We have often seen that העולם הזה haolam hazzeh, this world, of which του κοσμου τουτου is a literal translation, is frequently used to express the Jewish system of rites, ceremonies, and institutions in general; what the apostle calls the tradition of men, namely, what men, unauthorized by God, have taught as doctrines received from him. Our Lord frequently refers to and condemns these traditions.
Not after Christ - Not according to the simple doctrine of Christ, viz.: He died for our offenses; believe on the Lord Jesus, and thou shalt be saved.
