1 Corinthians 4:18
Now some of you have become arrogant, thinking that I would not [dare to] come to you.
1 Corinthians 4:6-8
Now I have applied these things, brothers, to myself and to Apollos as an illustration for your benefit, so that you might learn to "follow the written message." [Note: This is thought to have been a common way of referring, in that day, to the importance of adhering to Old Testament Scripture]. So, none of you should be more proud of one [leader] than of another.
1 Corinthians 4:21
Which do you [really] want? Shall I come to you with a rod [of discipline], or lovingly, and with a spirit of gentleness?
1 Corinthians 5:2
And you are arrogant [about it] instead [of being ashamed]. Should you not be grieved to the point of removing from your fellowship the person who has done this [terrible] deed?
