Spiritual maturity is a fundamental dimension of human development that can help inform macro and micro level social work practice. On the macro level we need spiritually mature leaders who can help form coalitions of spiritually maturing people across the boundaries of nation, religion, class, gender, culture, and race. At the micro scale, there is a need for spiritually mature parents, leaders, and professional healers who have the courage, wisdom, and skills required to help navigate families and local communities through the stormy seas of accelerating ecobiopsychosocial-spiritual change. It is our premise that this task of describing spiritual maturity can and must be accomplished. In this paper, we report the findings of a study we have conducted, which explored how 200 adults view spiritual maturity. Implications of these findings for local and global social work practice are then advanced.
