What the Bible says about Eloquence
(From Forerunner Commentary)
The false teachers Paul foresees will do the damage with their tongues. They will manipulate the brethren with cunning sermons and with seemingly logical arguments, but their motivation is to get for themselves. Jude says they "speak great swelling words" (Jude 1:16). They are full of bombast, and they sound quite appealing, but one must look beyond their eloquence and notice what they are really saying.
