In his anti-Wright book, Piper says

“Faithful Christians do not love controversy; they love peace. They love their brothers and sisters who disagree with them. They long for a common mind for the cause of Christ. But for this very reason they are bound by their conscience and by the Word of God to try to persuade the church concerning the fullness of the truth and beauty of God’s Word” (31-32).
I simply don’t believe that most polemicists love their opponents in any way, desire peace or want a common mind. They want and need to fight. I think they have a psychological need to right, and will divide from anyone in order to establish that game and win it. They redefine love and discipleship so that arguing and the various tools for winning arguments become “loving.” This may not be true for all, but it’s true enough to make Piper’s statement absurd in many cases.
