Deism is the belief in a monotheistic God that is the prime mover, establishing the universe and then letting it go. Unlike Theism the Deistic God does not suspend or interfere in the universe after its creation so does not interfere in human affairs picking sides, judging, or elevating the status of anyone above the rest because of faith or race. And even devout Theists admit that they do not see evidence for prejudice in their favor despite their piety and beliefs.
Thomas Paine, Benjamin Franklin and Thomas Jefferson were all Deists who inspired the worlds first constitution that would not use God in its formula. This prevented favoring of one theism over the rest,which had caused hundreds of years of competition for dominance by brutality throughout European history.
The core of Deistic beliefs then was the freedom from theistic tyranny to form a true concept of freedom of religion including and especially the freedom not to believe. So it became constitutionally illegal to commit crimes with impunity claiming Devine Right. In fact the Divine Right of Kings to rule by privelage established by theocracies for thousands of years was replaced by the Rights of Man to freedom from the tyranny of kings and the church.
“Inalienable rights…We hold these truths as self evident”…this is the product of reason. The separation of church and state meant that the state no longer could demand itself to be worshipped by association with a theocracy. And by limiting the authority of all religions to private and voluntary observances not beyond the regulation of secular morality allowed for true religious freedom for all by placing secular law superior to and in governance of any and all religion.
It is clear that religion cannot ethically and consistently regulate itself; Cardinal Ratzinger(Pope Benedict)admitted to physically abusing students of the school he ran in Portugal until the government created laws forcing him to stop. The Puritans tortured and burnt so called heretics and witches until it was stopped by legislation. Muslims are restrained in acts of religious violence(Fatwa and Jihad) in the West only for the fear of enforcement of secular laws. Jews are only restrained from genociding the Palistinians because of the fear of Secular International Law(It is clear from the book of Exodus that genocide, and infanticide were biblically authorized by their God in the then called land of Caanan, now called Israel/Palistine…with a clear mandate by God). Hindu infanticides and honor killings that their religion permits needs to be criminalized by secular authority, because it’s not going to stop itself.
It’s best not to forget what Theism has done in the past when they were free to behave with impunity, and push them back when they push otherwise they’ll create not a utopia but another man made hell. And so it’s not demons that need to be regulated by God, prayer and magic, but men that need to learn to regulate themselves without fantasy and delusion.
All theists present themselves as a “Smily Face”, and it remains that way until they don’t!
