The Christian Doctrine of the Trinity

Jim ButlerEphesians 1:3–14

The Christian doctrine of the Trinity — one God eternally subsisting in three distinct persons, Father, Son, and Holy Spirit — is defined, defended against historic and contemporary errors, and displayed across the whole of Scripture. The sermon works through three movements: first defining the doctrine precisely (one in essence, three in person), then defending it against polytheism, Arianism, and modalism, and finally displaying its pervasive witness throughout both Testaments. The doctrine is shown to be not a cold theological abstraction but the very foundation of salvation, worship, and the believer's communion with the triune God.
