In my opinion and based on research, we must first juxtapose the twin concepts of "love" and "depression". In my article "The Art of Selfishness", I write that the experience of LOVE is a sign that we are surviving, whilst the experience of depression is a sign that we are dying.

The Catholic Church describes 7 deadly sins including wrath, lust, slothfulness. These "sins" can be conveniently mapped to some of the symptoms of depression (anxiety disorder); anger/irritability, gluttony (lust for or addiction to food) and fatigue respectively.

Modern Science has unearthed certain "neurotransmitters" including Serotonin, Norepinephrine and Dopamine, the deficiency of which results in the aforementioned symptoms. It is common knowledge now that antidepressants such as Prozac or Paxil work as SSRI's (Selective Serotonin Reuptake Inhibitors) and have been described as happiness pills. Science also shows that MOST addictions stem from a deficiency in Dopamine (dubbed the LOVE neurotransmitter) as addicts strive for a faux love experience from cocaine, alcohol and even sex.

Treating these deficiencies with amino acids such as L-Tryptophan (for Setotonin), L-Phenylalanine (for Dopamine & Norepinephrine) results in an alleviation of lust, anger, slothfulness and instead the "patient" experiences "contentment", "calmness" and "productive energy". I don't think it requires even quantum leap of the mind to see how this transposes to a hypothesis that "sin" (redefined as symptoms of an anti-love, i.e. depression) can be [Bio]Medicated.

The key is to think laterally and to see "sin" as primarily a biochemical problem that can be treated by science and no longer primarily a function of the JudeoChristian faith with the Holy Spirit having the monopoly on its eradication.

Even the scriptures support the notion that SIN is of the "flesh", the material/physical component of the soul.
