The ICC began out of a deep conviction that believers should resolve all disputes within the church rather than in civil courts. See, e.g., 1 Corinthians 6:7. In 1970 members of the Christian Legal Society [CLS] initiated several regional Christian Conciliation Service ministries, including one started by Ken Sande in Billings, Montana. In time, these ministries became known as the Association of Christian Conciliation Services [ACCS] and later became the Institute for Christian Conciliation, which ultimately resulted in Peacemaker Ministries.
In 1991, Peacemaker Ministries founding director, Ken Sande, published a seminal book on Biblical peacemaking: The Peacemaker: A Biblical Guide to Resolving Personal Conflict, which has now been translated into 17 languages and remains the primary text for understanding Biblical peacemaking. Today, over 120 countries have been impacted by the faithful work of Christian conciliators through the vision and mission of Peacemaker Ministries.
In 2012, Ken Sande launched a new ministry Relational Wisdom 360, and Peacemaker Ministries moved to Colorado Springs under the leadership of Dale Pyne where it continues to thrive and teach Resolving Everyday Conflict and The Path of a Peacemaker.
In 2016, Peacemaker Ministries transferred ICC ownership to ICC Peace, an organization of experienced conciliators and Christian attorneys, to steward the specialized work of conciliation, training, and certification.
