Universalism is the other half of the religious tradition known as Unitarian Universalism. I already dealt with the first half by denying the Trinity as a self-contradicting assertion:
It is understandable that some people want to feel like they are better than others or more loved by God than others, but that is an appeal to the human ego that is destructive to human spirituality. There is nothing more vile than the idea that God would condemn anyone to eternal damnation in hell for believing in the “wrong” dogmas. Such extreme punishment could only be justified if there was some empirical way to discover the truth in religion, thus making it beyond dispute. But if that was the case, it wouldn’t even be religion at all; it would be SCIENCE.
In the late 1980s, I was a Christian and I was perfectly sincere about it. Then at the turn of this Century, I was a Baha’i and just as zealous about that. And in both cases, I have turned away from those religions because I found them to be flawed and unworthy of my allegiance, perhaps even completely false, as many do believe. But if I had died at either time, would it have been fair for God to condemn me for following a false religion?
Even if Christianity was the only true religion, the fact that it has been divided into thousands of competing sects, despite the fact that Christians are supposed to believe in one God and one savior, is enough to show that there are no “true” Christians. No matter what position you take, you are part of a minority in the world; Christians only make up about 1/4 of the population of the world. Is it logical to assume that God would condemn the vast majority of the world for not being Christian, especially when there is so much evidence that it is defended by outright fraud?
1900 years ago, Christians and Jews were a tiny minority in the world. In places like India, China, Japan, and the American continents, there was virtually no chance for people living there to hear and accept the teaching of either Bible based religion, while there were religions like Hinduism, Buddhism, Confucianism, Taoism, Shinto, or the various Pagan religions. Who could blame the people in those lands for following what they knew? It is easy to assume you have the only true faith when you have only that one faith in your community and do not know followers of other religions except through crude stereotypes. Once you get to know those followers as people, those stereotypes tend to break down. Exposure to those people breeds tolerance quite naturally.
Since there is no way to know what truth in religion is, there is no justification for the dogma that God damns anyone for what they believe or disbelieve. That claim is bigotry and thus is evil.
