I looked at it and did the questionnaire he supplies.
The scientific criticism is valid, there's no direct link between his scans and the outcomes. He uses the science as a correlation for everyday self help stuff and catholic salvation.
It's not coincedence he talks about believing in miracles and jokes about wanting to become a catholic priest as a child. He grew up seriously into the church.
People are essentially paying for salvation and at a steep price, this is exactly why the protestant churches got started. Look closer!
