Douglas Wilson and Randy Booth from A Justice Primer:

In a public setting, it is necessary for the accuser to be prepared to prove what he says. In order to that (is this starting to sound familiar?), he must not be anonymous, he must be accountable to a body for his charges (in case they prove deliberate falsehoods), he must have independent confirmation of what he says (2-3 witnesses). If these conditions do not pertain, a church body is prohibited by Scripture from entertaining the charges (I Tim. 5:19). When authorities unsubstantiated charges, they are not covering anything up. They are being obedient. 

From Douglas Wilson & Randy Booth’s A Justice Primer:

Witnesses must be accountable to the appropriate court, and must be in a position whereby they can be cross-examined. Thus anonymous accusations must be rejected as unsubstantiated and considered not credible…not all witnesses are to be believed…Multiple credible witnesses are required before even receiving an accusation against an elder (I Tim. 5:19)…Malicious false witness violates the ninth commandment and inflicts serious damage on our neighbor. Negligent or careless false witness is also a breaking of the ninth commandment and can have similar effects. Our obligation is to honestly and accurately represent others when we disagree with them, not to assume that we know what they really meant. 

From Douglas Wilson and Randy Booth’s A Justice Primer:

Autonomy seeks to replace the perfect law of God-which is perfect justice-with our own standards of justice. Justice demands an authority. By what standard will we evaluate fairness? Who will execute or enforce justice? Is this standard and authority infallible? How are the standards to be applied? Who says? These are all inescapable questions. Some standards will be used and some authority will stand behind those standards. The alternatives are limited. Essentially, we can choose between autonomy and theonomy-man’s law or God’s law. One of these standards will be the ultimate authority and arbiter of justice.
