I like what you're trying to do here, Van. I have read some of Percho's posts on this issue, and I think he has some good insights. And I even think he and I might have the same exact view.
But as you've noted, it is very hard to determine exactly where he stands because of his writing style.
Romans 8:15 Nasb
For you have not received a spirit of slavery leading to fear again, but you have received a spirit of adoption as sons by which we cry out, "Abba! Father!"
pretty much derails van here!
