If that 5% is indeed true, Ray, the Church is in serious trouble. Conversion is supposed to produce a metanoia, change of mind (heart). 

We see what a profound realization of our mortality can produce by looking at the effects of Near Death Experiences (NDEs).
For the majority, their "whole attitude and outlook upon life" is fundamentally altered to a new and joyous direction in an extremely brief period of time--without effort or intent, without the help of any belief system or ideal, without the instruction from any preacher, guru, or holy book, without any apparent penance or process.  All they had to do to "achieve" this wondrous and Dynamic Conversion was to have the good grace to...die.  

The Recovery process is, as well, a form of metanoia.  

I think it safe to say that we can safely throw out that textbook, at least I pray we can.
