SEMINAR 2.2

The One and the Three

How does Christian confession name real distinction without partition and unity without modal collapse?

THE ARGUMENT
Trinitarian doctrine is the grammar by which Christians identify the one God revealed in the missions of Son and Spirit.

This seminar reconstructs the Nicene grammar of one divine essence and three irreducible persons. It moves from biblical missions through fourth-century controversy to Eastern and Western accounts of relation.

Learning sequence4 lessons
  1. 01

    From missions to identity

    Trinitarian doctrine begins with the identity of the one sent, raised, worshiped, and given in the economy.

  2. 02

    The Nicene rule

    Homoousios protects the claim that the Son gives God rather than a supreme creaturely intermediary.

  3. 03

    Relations that subsist

    Personal distinction is constituted by relations of origin within the undivided divine life.

  4. 04

    The rule and its limits

    The doctrine does not explain God from above; it disciplines faithful speech before mystery.
