By Elder Porphyrios of Kapsokalyva
Our purpose is not to condemn evil, but to correct it. With condemnation people can get lost, with understanding and assistance they will be saved.
Evil begins from bad thoughts.
When you are bitter and indignant, even just with your thoughts, you spoil a spiritual atmosphere. You prevent the Holy Spirit from acting and allow the devil to increase the evil.
You should always pray, love and forgive, driving out of yourself every evil thought.
