Some thoughts on the ninth commandment (“You shall not give false testimony against your neighbor”) at joethorn.net:
Look, if you think someone’s theology is dangerous, then deal with it. Use the man’s words, and show where his words speak heresy or false doctrine. I believe this is one of the tasks of our pastor-theologians and professors. But it must be done with care and precision, not passion and presumption. This forces everyone to be honest and fair.
Misrepresenting the ideas of another is both a misrepresentation of the truth, and it is unbecoming of the church. Such habits are satanic, and the danger is double because it encourages others to repeat the lie and spread the sin. As Watson put it, “A false witness perverts the place of judicature; he corrupts the judge by making him pronounce a wrong sentence, and causes the innocent to suffer.”
