And not only this, but also after this another question hence springs up: since the tongue will appear on the contrary greater than the prophecy. For if the tongues are for a sign to the unbelieving, but prophecy to them that believe, that which draws in aliens and makes of the household, is greater than that which regulates those of the household. What then is the meaning of that expression? Nothing difficult nor obscure, nor contrary to what went before, but rather very agreeable to it, if we give heed: viz., that prophecy is suitable to both, but then tongue not so. Wherefore having said of the tongue, “it is for a sign,” he adds, “not to them that believe, but to the unbelievers,” and to them “for a sign,” i.e., for astonishment, not so much for instruction.
