As a Bible-based organization, we must adhere to what the Scriptures say, namely, "No single witness should rise up against a man respecting any error or any sin . . . At the mouth of two witnesses or at the mouth of three witnesses the matter should stand good." (Deuteronomy 19:15)This is what the Society bases its "two witness" rule on...
You quoted this out of context as the following line says:
However, if two persons are witnesses to separate incidents of the same kind of wrongdoing, their testimony may be deemed sufficient to take action.So their two witness rule is NOT limited to witnesses to the same event. All they need is two accusations to act against someone denying charges. Do you think it should be otherwise? Do you really think that a single accusation against a person should mean they are guilty? I'm glad our court systems don't work that way...
