Fr. Alexander Schmemann provided this summary of the three key areas of confession:
Relationship to God: Questions on faith itself, possible doubts or deviations, inattention to prayer, neglect of liturgical life, fasting, etc.
Relationship to one's neighbor: Basic attitudes of selfishness and self-centeredness, indifference to others, lack of attention, interest, love. All acts of actual offense—envy, gossip, cruelty, etc.—must be mentioned and, if needed, their sinfulness shown to the penitent.
Relationship to one's self: Sins of the flesh with, as their counterpart, the Christian vision of purity and wholesomeness, respect for the body as an icon of Christ, etc. Abuse of one's life and resources; absence of any real effort to deepen life; abuse of alcohol or other drugs; cheap idea of "fun," a life centered on amusement, irresponsibility, neglect of family relations, etc.
