A recent study out of Georgia State University shows that in some cases sharing the Christian faith with prisoners might cause them to commit more crimes. According to the study’s abstract,
Through purposeful distortion or genuine ignorance, the hardcore offenders we interviewed are able to exploit the absolvitory tenets of religious doctrine, neutralizing their fear of death to not only allow but encourage offending.
Basically, the criminals took advantage of God’s unlimited ability to forgive and held to the mistaken notion that as long as they ask for forgiveness after their crimes they will still go to heaven.
Some aspects of Protestant theology (which may be espoused by some of these prison chaplains) does lead to the idea that no matter what a human being does after he has been “saved,” that person will eventually go to heaven.
I have seen this kind of thinking myself among fundamentalist Baptists.
