In a very bizarre article, Triablogue claims that Open Theism is a variant of Manichaeism:
All the various religions and philosophies past and present are variants on three basic worldviews: Calvinism, atheism, and Manichaeism.
For example, freewill theism in its various forms (e.g. Arminianism, open theism) is a variant on the Zoroastrian or Manichean outlook on life. Representatives of this viewpoint include Zoroaster, Mani, Arminius, Wesley, Roger Olsen, Clark Pinnock, and Gregory Boyd–to name a few.
The theology of the Arminian, Manichaean or Zoroastrian is essentially and radically dualistic. He may claim to be a monotheist, but he’s really a bitheist or ditheist. In his theology, “God” is a code word for the good God (Zurvan/Ahura Mazda) while “Satan” is a code word for the evil God (Ahriman/Angra Mainyu).
Triablogue’s reasoning seems to be that in Open Theism or Arminianism, Satan is an opposing force of evil against God’s good. In Manichaeanism, there are forces of good in conflict with more powerful forces of evil. If this is the only aspect one is looking at, much of Christianity seems like Manichaeanism. But how many Christians think that “evil” is an inherent part of the world, that is could not “not exist”? When this question is answered, a lot of perceived dualism fades into nothingness.
I wonder how this Triablogue’s bizarre views fit with the Arminian Michael Heiser (and like-minded Open Theists) who claims there is no Satan in the Old Testament. Rabbi Sacks, a Jew, would also counter this dualistic mentality. Good versus evil metaphysics is an invention of Christian theology. None of these people are atheists, Calvinists, or believe in dualism. Triablogue seems very uninformed both on what people believe (and the basics of Manichaeanism, for that matter).
Triablogue doesn’t show much intellectual integrity in his trinity of worldviews. Instead of Calvinism, he would do well to replace the word with Platonism, but this does not fit what he is trying to sell. He tries to sell with emotional appeals to security over the future, although in Calvinism God predestined unmitigated evil for His glory. How on Earth would this give someone security. Triablogue would also do well to do a preliminary reading of the Psalms. In the Psalms he will find all sorts of non-Calvinists with little future security. Apparently the Psalms were written by Manichaeans.
