Hank Hanegraaff, radio's "Bible Answer Man," is suing Chrisitan blogger Wiliam Alnor. You can read the details at CT.
On why CRI is taking a fellow believer to court, Hanegraaff told CT that Christians should never do so in an arbitrary fashion, but, "At some point, you have to say, 'Enough is enough.' Truth and justice do matter."
Hanegraaff added, "If you don't respond, people think there may be something to it."
Read that last line again, and then read Paul's exhortation to the Corinthians:
1 Corinthians 6:1 When one of you has a grievance against another, does he dare go to law before the unrighteous instead of the saints? 2 Or do you not know that the saints will judge the world? And if the world is to be judged by you, are you incompetent to try trivial cases? 3 Do you not know that we are to judge angels? How much more, then, matters pertaining to this life! 4 So if you have such cases, why do you lay them before those who have no standing in the church? 5 I say this to your shame. Can it be that there is no one among you wise enough to settle a dispute between the brothers, 6 but brother goes to law against brother, and that before unbelievers? 7 To have lawsuits at all with one another is already a defeat for you. Why not rather suffer wrong? Why not rather be defrauded?
