Although the evidence indicates that the Watchtower Society never signed or completed one document that said they would support the United Nations, for a moment let's do as many critics do, and pretend that the evidence doesn't exist. Let's pretend we have evidence that the Society did indeed sign a document where they agreed to support the UN and the principles of the UN's charter. What implications would such an agreement have? Would it compromise our Christian beliefs?
The word “support”, in English, is a general term, and we are not at all helped in defining exactly what it means to the UN. In their documents they do not stipulate exact specifications of what it means to support the UN and the principles of their charter — neither in a practical nor philosophical sense.
According to Websters, when the word “support” is used as a verb, can mean to “uphold or defend as valid; to furnish corroborating evidence for; to act in a secondary or subordinate role to.” Using these definitions, what are the implications of supporting the UN and it's charter?
When the Watchtower Society began educating the public on the United Nations and it's place in Bible prophecy from 1945 onwards, it could be said that our support was to “furnish corroborating evidence for” to the UN whether we intended to or not — at least in the sense of educating the public in what the UN is, what it is there for, and what it does. The UN wants the public to know about its existence and relevance in the world. That is why even organizations which criticize the UN's failings can remain DPI NGOs — as did the Watchtower Society. Since the DPI is there to disseminate information it is reasonable to believe that the definition “to furnish corroborating evidence for” would be the applicable definition for the word ‘support’ in this case.
However it is also true that by being “in subjection” to the governments as Romans 13 tells us to do, we are supporting them in that we are acting in a “secondary or subordinate role.” It says:
“Everybody must submit to the ruling authorities for none exists without God's permission and it is he who puts them in their place. So
anyone who opposes the authority is setting himself against God's arrangement, and those who do so will only bring punishment upon themselves. ... So pay to all what is due, the property tax to the tax collector, customs to the customs officer, and
respect and honour to all whose positions call for it.” —Romans 13:1-2, 7; 21st Century New Testament, Insight Press, Bristol, UK
Lets say that the definition to “uphold or defend as valid” is what is meant by the word ‘support.’ By paying our taxes and being in subjection to God's arrangement, true Christians support and encourage the rule of law and the authority of all human governments, for by doing any different we would be setting ourselves “against God's arrangement”. We uphold and defend as valid the application of the constitution of the country we live in when it does not conflict with Bible principles. For example, this would particularly apply to the right to choose and practice one's own faith. This includes the Bill of Rights if you live in the United States, the European Convention on Human Rights if you live within the European Union, and the Universal Declaration of Human Rights within every UN member state.
Furthermore, we use the court system of many countries to advance true worship; Many brothers and sisters sign documents which state they will protect the constitution or laws of the land they reside in. Yes, we support and encourage the rule of law and the authority of the governments put in place by God, for “none” exists without God's permission and “it is he” who put them in their place — yes, including the United Nations.
