He’s getting cannier about knowing that people are going to fact check him. Notice that he makes a point of mentioning that this is “that this is only his opinion” and will be on YouTube.
But then he goes on to mocks the ‘freshman theologians’ who are going to disagree with them and says they haven’t ‘studied it as much as he has.’ He’s claiming it without claiming it to leave himself wiggle room. It’s subtle but it’s there.
I suspect that a lot of those skulls full of mush are going to leave that room telling it as fact because it’s what their preacher believes.
