This is a weird one. "You can quote him, but he doesn't actually mean what he's saying!"
Do you too wish to separate words from their context? He's trying to conflate technical vocabulary with general vocabulary and insisting he's correct, in addition to ignoring part of the speech in which limitations are explicitly said, which he ignores when he promotes his conception of the "Monarchian Trinity".
Let's use an example Protestants will understand, as generally speaking, you accept that there are different meanings for the word "love" (agape, philios, eros etc.). What makes you think Fr. Trenham is using "origin" or "monarch" in colloquial terms?
The idea that "Protestant theology doesn't exist outside of its founders" is a bizarre statement , bordering on the nonsensical. That's like saying that Mount Everest doesn't exist outside of Edmund Hillary, who first climbed it.
That's a terrible analogy, as Choppa is referring to ideas. You cannot conflate that he's saying a physical place wouldn't exist unless someone first interacted with it's physical heights. (I'm using "exist" as it's used in everyday terms) Marxism wouldn't exist without Karl Marx. Freudian psychology wouldn't exist without Sigmund Freud. Calvinism wouldn't exist without John Calvin.
