Lesson 1: Monotheism demands exclusivity and evangelism. The trend is for monotheistic world-views to push out others.
It’s no surprise that when a worldview claims to be right that the implication is that the others are wrong. Monotheism by its nature creates evangelists who testify to its truth at the cost of competing world-views. As time goes on, polytheistic religions are pushed to the background. The postmodern movement has popped up recently advocating a world-view with various subjective “truths,” but history will not be kind to a type of neo-polytheism.
Adherents of the two large monotheistic world-views, Christianity and Islam, will soon be the majority of world population. A third competing worldview is a non-religion, “none’s” or we used to say “secular humanism”. Though growing some in the West, this world-view is a rapidly declining worldwide. Adherents of this world-view try to escape the normal scrutiny of world-views by simply declaring that they aren’t one. People who believe this deception often decry that a Christians’ contribution to public discourse is out-of-bounds because it’s “religious” all the while using similar sounding talk of ethics, values, etc. That’s a nice trick for university professors, politicians, and some bloggers, but not for serious thinkers.
I’ll post the other lessons soon.
