"OK, then would you equate sin with "evil", as I would? Or, is "missing the mark" more like mistake, or something else? How do you see the concept of evil?"
One of the problems with Western praxis is this idea of a sort of incohate "evil". The last words of the Our Father are a good example "...but deliver us from evil". In fact the Greek says "...but deliver us from the Evil One". The Evil One and his demons may lead us to so live our lives as to fail to become "like Christ", to miss the mark. If we commit murder, have we sinned? Yes and we have done an evil thing. If we lead our lives in such a way as to fail to "die to the self" but rather lead a life of self-fulfillment, not by committing any of the seven dealy sins, but perhaps by a life of study of ancient pottery and hurt no one, have we committed evil? No, but have we missed the mark and thus sinned? Yes.
I think Kosta answered the first question. I would only add that for Christ to "sin" he would have to un Christ-like, an odd thought.
Are the seven deadly sins then the test of evil? Or, were you just using an example? I did not know of this distinction between sin and evil.
