Using your frame I can't really fault any of your criticisms, and really appreciate you engaging, as I know from twitter you are no slouch!
I readily admit to Orthodox and Catholic theology and structure being the weakest wheels in my wheelhouse, but their general historical social functions informed my meanderings greatly. Their advantages and disadvantages helped me understand better the value of centralized structure and doctrine as emergent properties, NOT centrally planned top-down. Some humans along the civilizational and spiritual growth timeline will always need more structured, centralized forms of sense-making. For me, this is perfectly fine.
I also want to be very clear that I personally do not hold myself above practitioners of these "brands" spiritually and certainly not intellectually. I have the highest respect for the Orthodox and Catholic mystics that we, the Scripture Fiends, so frequently have to find in the restricted section of the church library. Without my own mentors blazing that trail and guiding me into a deeper understanding of the faith, I would surely be lost.
I am spiritually and politically Protestant in my mentality. But over the past year, I have found myself loudly criticizing American evangelical churches for being lazy, disorganized, thoughtless, judgmental, lovers of money and comfort, and wasteful of what they have been blessed with. They're my tribe... I will always criticize them the most harshly! When Charlie Kirk got assassinated, my second response was, "ohhhh nooooo... SO many people are going to get hurt and led astray when they rush back into the local Prot church." Likely less so with the more mature structures, to the credit of your traditions.
The name...uhh... I wouldn't be surprised if it bothers you, some casual, cribbing your identity and using it wrong on purpose. In this regard I hope you forgive me.
I chose the name and acronym precisely because it tickled my "pisses off so many different people all at once" bone. I guess I wanted it to attract and repel the right kind of attention.
I intend to read through the Calvinism doc, and think about your specific questions with some care, before responding again. No easy answers here, folks.
Humbly,
Steve
