He is proud, knowing nothing, but doting about questions and strifes of words, whereof cometh envy, strife, railings, evil surmisings, He is proud - Τετυφωται· He is blown up, or inflated with a vain opinion of his own knowledge; whereas his knowledge is foolishness, for he knows nothing.
Doting about questions - He is sick, distempered, about these questions relative to the Mosaic law and the traditions of the elders; for it is most evident that the apostle has the Judaizing teachers in view, who were ever, in questions of theology, straining out a gnat, and swallowing a camel.
Strifes of words - Λογομαχιας· Logomachies; verbal contentions; splitting hairs; producing Hillel against Shammai, and Shammai against Hillel, relative to the particular mode in which the punctilios of some rites should be performed. In this sort of sublime nonsense the works of the Jewish rabbins abound.
Whereof cometh envy, strife, etc. - How little good have religious disputes ever done to mankind, or to the cause of truth! Most controversialists have succeeded in getting their own tempers soured, and in irritating their opponents. Indeed, truth seems rarely to be the object of their pursuit; they labor to accredit their own party by abusing and defaming others; from generals they often descend to particulars; and then personal abuse is the order of the day. Is it not strange that Christians either cannot or will not see this? Cannot any man support his own opinions, and give his own views of the religion of Christ, without abusing and calumniating his neighbor? I know not whether such controversialists should not be deemed disturbers of the public peace, and come under the notice of the civil magistrate. Should not all Christians know that the wrath of man worketh not the righteousness of the Lord?
