For health

I have made mention of this in prior posts, but never as a main topic, I believe.  The Orthodox understanding of the church is radically different than that of Protestantism.  I won't put words into Protestant mouths, but I can speak for Orthodoxy.  One of the main values of church is its healing properties. In this I am talking about health of the soul.  If we come down with some sort of physical ailment, a cold, the flu, chicken pox, an appendicitis, etc. we go see the doctor, or go to the hospital and we receive physical treatment from someone who has the knowledge and training to lead us back to health, through surgery or medicine.
The very same thing can be said of sickness of the soul.  Since the fall of Adam, man's soul has been darkened, diseased and distracted.  THE answer to this is the church.  Regular, consistent, whole hearted involvement in the Divine Liturgy, repentance, confession and the sacraments will purify our soul and prepare us for eternity.  Some may balk at this, but it makes perfect, logical sense.  Just as physical, tangible medicine will heal our bodies, so too, mystical, spiritual things will be medicine for our souls.
Just as it takes months and years to change a flabby body into a fit one, it will take years to change a diseased, darkened soul into an enlightened one.
