At Eden, Man chose to abuse his freedom, distrusting God and seeking to “be like God” (cf. Gen 3:5). Since then, Man has suffered under the effects of Original Sin (CCC 396-409), which includes the embrace of personal sin and lives full of pain, illness, emotional suffering and death.
Humans have sought to alleviate suffering through modern medical advances to treat mental and physical illnesses. Modern psychology and psychiatry seek to treat mental illness with cognitive behavioral therapy and various medicines. Modern physical medicine has made great advances in treating all kinds of bodily illness through diagnostic technology, scientific treatment protocols, pharmaceuticals and surgical procedures.
