Having a Pastor for a brother & someone with PTSD as a mom... I,can say this is poppycock. There are literally Christian psychologists that see believers and not believers alike. Churches also offer marriage counselling at no cost often, house Anonymous Meetings for addicts to get better, and teach their congregations to seek medical help for medical problems.
Extreme faith bases organizations exist that preach to pray it away, but they are few and far between.
