Galatians 1:7

which is not another gospel: only there are some that trouble you, and would pervert the gospel of Christ. [This verse defines the meaning of that which precedes, so as to correct the false impression that there might be two gospels, similar in sonic respects and equally effective. The folly of such a thought is ironically set forth at 2 Corinthians 11:4. There is, says the apostle, emphatically but one gospel, but there are some who would revolutionize you (the word "trouble" has this force) by perverting the gospel, making it an unholy, ineffectual compound of living truth and obsolete Jewish forms. His failure to name the leaders in this movement shows his contempt for them. They were parties unknown and deserving to remain unknown. One can not help wishing that modern churches would waken to the truth here spoken by the apostle. There is and must ever be but one gospel. There is not a separate gospel suited to the prejudices or so-called "tastes" of each sect or denomination. There is but one gospel, and hence all church divisions result from perversions of that gospel, and all such secessions or revolutionary divisions are but the beguiling of Satan, drawing disciples from "the simplicity and purity that is toward Christ"-- 2 Corinthians 11:3]
