Pertaining to the OP, I don't much blame some churches for no-medicine beliefs, as I have the same stance myself, but not for faith reasons. Trauma medicine is OK as compared to the Good Samaritan who would bandage up the wounds of someone attacked is a form of "medicine".
However, like many things that take on a worldly philosophy, the rest of medicine has become highly economically and politically charged, especially "preventative medicine" which drugs are dished out like candy to lower various numbers thus giving the severe delusion a person is healthier as any medication that merely lowers numbers is basically worthless. Even "insurance discounts" are given to people who sheepily obey but in fact the programs are worthless but lines the pockets of drug makers. In that case, I can understand how some churches take this worldly politicking and equate that to lack of faith that serves the enemy.
But on the pragmatic level, I'm not saying there are not truly good Samaritans in medicine.
