I have seen the Matthew Joyner's case until around minute 17:00 enough to know that he fits
what you said above. But while he was influenced by books by JI Packer and RC Sproul and by his understanding of PSA, I'm actually rather turned off by them. So in my current state, if the Catholic church didn't require the dogmas about Mary and Papal Infallibility, I would have become Catholic already.
