Calvary Chapel affirms the classical Trinitarian doctrine: one God eternally existing as Father, Son, and Holy Spirit, three distinct persons sharing one divine nature. This is considered a non-negotiable foundational doctrine of the Christian faith.

The Calvary Chapel Distinctives document and its Statement of Faith explicitly affirm the Trinity as defined by the early ecumenical councils and reflected in the Nicene Creed. Pastors are expected to teach and defend Trinitarian theology as a core commitment.
