Romans 2:20

Second, he touches on those who are on the way to knowledge they have not yet attained, in one way through lack of full instruction; hence he says, an instructor of the foolish, i.e., of those who have not yet received wisdom who are said …

An instructor of the foolish,.... All men in a state of unregeneracy are foolish, and need instruction; here the common people among the Jews, who knew not the law, are meant; it was very usual to call anyone of their doctors and masters מורה, "an instructor": it follows, a teacher of babes; either in age or in understanding; such who taught either of them were called by the Jews מלמדי תינוקות, "teachers of babes". Thus they paraphrase the text in Dan 12:3, "they that be wise, shall shine as the brightness of the firmament.

Apply it, (1.) To the Jews in general. They thought themselves guides to the poor blind Gentiles that sat in darkness, were very proud of this, that whoever would have the knowledge of God must be beholden to them for it. All other nations must come to school to them, to learn what is good, and what the Lord requires; for they had the lively oracles.

It was a very honourable title. Salvation was of the Jews; and this they were very proud of, to be a people by themselves; and yet many that were so called were the vilest of men. It is no new thing for the worst practices to be shrouded under the best names, for many of the synagogue of Satan to say they are Jews ( Rev. ii.

), The form of knowledge, and of the truth in the law, that is, the show and appearance of it. Those whose knowledge rests in an empty notion, and does not make an impression on their hearts, have only the form of it, like a picture well drawn and in good colours, but which wants life.

An instructer of the foolish, etc. - Ye believe the Gentiles to be babes and fools when compared with yourselves; that ye alone possess the only true knowledge; that ye are the only favourites of Heaven; and that all nations must look up to you as possessing the only form of knowledge, μορφωσιν της γνωσεως, the grand scheme and draught of all true science, of every thing that is worthy to be learned: the system of eternal truth, derived from the law.

Behold--"But if" is, beyond doubt, the true reading here. (It differs but in a single letter from the received reading, and the sense is the same).

hast the form of knowledge and of the truth in the law--not being left, as the heathen are, to vague conjecture on divine things, but favored with definite and precise information from heaven.

Of the foolish - The word “foolish” is used in the Scriptures in two significations: to denote those who are void of understanding, and to denote the wicked. Here it is clearly used in the former sense, signifying that the Jew esteemed himself qualified to instruct those without knowledge. Of babes - This is the literal meaning of the original word. The expression is figurative, and denotes those who were as ignorant as children - an expression which they would be likely to apply to all the Gentiles. It is evident that the character bare given by Paul to the Jews is one which they claimed, and of which they were proud. They are often mentioned as arrogating this prerogative to themselves, of being qualified to be guides and teachers of others; Mat 15:14; Mat 23:2, Mat 23:16, Mat 23:24. It will be remembered, also, that the Jews considered themselves to be qualified to teach all the world, and hence evinced great zeal to make proselytes. And it is not improbable (Tholuck) that their Rabbies were accustomed to give the names “foolish” and “babes” to the ignorant proselytes which they had made from the pagan. Which hast the form of knowledge - The word translated here as “form” properly denotes a delineations or picturing of a thing. It is commonly used to denote also the appearance of any object; what we see, without reference to its internal character; the external figure. It sometimes denotes the external appearance as distinguished from what is internal; or a hypocritical profession of religion without its reality; 2Ti 3:5. “Having the form of godliness, but denying its power.” It is sometimes used in a good, and sometimes in a bad sense. Here it denotes that in their teaching they retained the semblance, sketch, or outline of the true doctrines of the Old Testament. They had in the Scriptures a correct delineation of the truth. […]
