Entering into covenant with others implies ethical responsibilities for right relationship. An important ingredient in "right relationship" is a sense of justice, a sense of fairness.
This idea of fairness or justice in right relationship is always bilaterally or multilaterally defined by the parties involved. It can't be effectively imposed on the those in relationship by an external source although we try to do this all the time.
What happens when there is an offense to one of the parties sense of fairness in relationship is anger, hurt, resentment and a deep desire to want to rectify the sense of injustice. This leads to either withdrawal, retribution, or an attempt to engage in clarification and rectification. Sometimes people move too quickly to "forgiveness", placating, or avoidance trying to avoid further conflict.
Forgiveness cannot be granted unless the sin is named, and in an effort to save face and avoid shame either the perpetrator becomes defensive and refuses to engage honestly in the naming process or the victim decides, in the interest of restoring the status quo, to avoid clarification and naming the injury, the offense, the sin.
An important ethical skill is the ability to name our sins, to accept responsibility for our part in ethical breaches. We live in a society which prizes its right to avoid responsibility. Our whole criminal justice system is based on an adversarial model wherein the perpetrator is given the right to not incriminate him/herself. While there may be some value in this for a criminal justice system, it is a corrosive idea from an ethical perspective. Taking responsibility is not only necessary for true justice to occur, but it is necessary for the restoration of right relationship.
Spiritual growth requires honesty, integrity, and the assumption of ethical responsibility. There are huge personal and social forces which oppose this value. The second principle of Unitarian Universalism is "justice, equity, and compassion in human relations," and it is one of the most difficult to implement and live by.
In the recent conflict in the church I used to belong to there was an attempt at clarification and reconciliation, but it left me bereft because the effort was to help people save face, gloss over the ethical breaches, in an attempt to dispel the bad feelings, and help people "feel better" and "love one another" but we have not named the sins and without an assessment of the harm done it is difficult to successfully repair it.
Reconciliation is not about helping the distressed parties to feel good, but to identify the harm which has occurred and generate ideas about how to repair it. This sadly did not occur and this church family is DOA, dead on arrival.
When injustice has occurred, it is important to call a spade a spade, take the bull by the horns, and get things straightened out. Whitewashing to spare people their feelings usually doesn't work. However, having the courage to be honest and take responsibility is the elixir of human integrity. Without that, relationships cannot continue with any meaningful genuineness which provide the context, the soil, for vibrant spiritual growth.
