John Chrysostom

"For whereas there is among you jealousy and strife."

At this point he prepares himself to wrestle with those whose part was obedience: for in what went before he hath been casting down the rulers of the Church, where he said that wisdom of speech is nothing worth. But here he strikes at those in subjection. And he points out that this, so far from helping them at all or causing them to acquire any thing, had even become an obstacle to their profiting in the greater things. For this it was which brought forth jealousy, and jealousy had made them "carnal;" and the having become "carnal" left them not at liberty to hear truths of the sublimer sort.
