This document outlines a systematic theology for mental health, beginning with an introduction by Dr. Evelyn Reed, who specializes in Christian doctrine, pastoral care, and health sciences. The text emphasizes the urgent need for a robust theological framework to address the contemporary mental health crisis, arguing that the church's historical role has been contradictory—both a source of healing and harm. It proposes a "two books" methodology, integrating biblical revelation with scientific findings, and advocates for an "Allies" model that fosters critical dialogue between theology and the behavioral sciences. The document then applies various Christian doctrines—including the character of God, human nature (Imago Dei), sin, Christology, salvation, and the Holy Spirit—to understand and address mental suffering, concluding with a vision for the church as a sanctuary and the eschatological hope for complete healing.
