“Justice often has to do with public accusations and charges that are denied by the one accused. When that happens, it is necessary for the accuser to be prepared to prove what he says. In order to do this, he must not be anonymous, he must be accountable for his charges (in case they prove deliberate falsehoods), and he must have independent confirmation of what he says. If these conditions are not met, we are prohibited by Scripture from even entertaining the charges (there must be two or three credible witnesses).”
