Calvary Chapel affirms the classical Christian understanding of God as one infinite, eternal, omniscient, omnipotent, and omnipresent Being who is personal and relational. God is holy, loving, just, and sovereign, and has revealed himself in creation, Scripture, and supremely in Jesus Christ.

The Trinitarian nature of God — Father, Son, and Holy Spirit — is central to Calvary Chapel's theology. God is not merely an abstract force or impersonal deity but a personal being who desires relationship with humanity. This shapes Calvary Chapel's worship style and its emphasis on a personal walk with God.
