The Trinity

major Trinity

God is one in essence and three in persons.

This doctrine defines Christian orthodoxy. Denial places one outside the historic faith.

What the traditions say

Roman Catholic affirms_strongly Catholic

Central dogma. The filioque clause ("and the Son") added to the Creed in the West, affirming the Spirit proceeds from Father and Son.

Lutheran affirms_strongly Lutheran

Augsburg Confession I: "There is one divine essence...yet there are three persons." Lutheranism stands squarely within Nicene orthodoxy.

Eastern Orthodox affirms_strongly Orthodox

Affirms the Trinity but rejects the filioque. The Spirit proceeds from the Father alone (through the Son, in some formulations). This is the central dogmatic disagreement with Rome.

Patristic affirms_strongly Patristic

Developed through the Arian controversy and defined at Constantinople (381). The Cappadocian Fathers gave the definitive formulation: one ousia, three hypostases.

Reformed affirms_strongly Reformed

Westminster Confession II.3: three persons "of one substance, power, and eternity." Reformed theology often emphasizes the economic Trinity — the ordered work of Father, Son, and Spirit in salvation.

Secular Critical reinterprets Secular Critical

Critical scholarship traces Trinitarian theology from NT "binitarianism" through 2nd-century development to Nicene formulation. Viewed as theological evolution, not divine revelation.

Rabbinic Jewish rejects Jewish

The Shema (Deut 6:4) declares God is one. Trinitarian theology is seen as a departure from biblical monotheism.
