Clement of Alexandria

It teaches the magnificence of the wisdom implanted in her children by instruction. Now the apostle says, "I will know not the speech of those that are puffed up, but the power; for the kingdom of God is not in word." By which is clearly revealed that the gnostic does not sin in speech, nor is puffed up by talk, but is full of work, having made his whole life in accordance with the Lord's commands.
