Origin
Plan, overall verdict and verification status of the former trinity category (shared with the other doctrines that came from it)
The Trinity and the filioque
Method and conventions: docs/conventions.md. Reasoning: trinity reasoning. Traditions’ sources: confessional sources.
1. Plan
Questions: T1 one God in three co-equal, consubstantial persons; T2 the procession of the Holy Spirit (from the Father, through the Son, or ‘and the Son’). Scripture: Matt 28:19; John 1:1; 10:30; 14:16, 26; 15:26; 16:7, 14–15; Gal 4:6; 2 Cor 13:14. Fathers: Ignatius, Ephesians 7; Tertullian, Against Praxeas 2; Nicaea (325); the Creed of Constantinople (381); Gregory Nazianzen, Oration 31; Augustine, On the Trinity XV.26; John of Damascus, Exact Exposition I.8. Later: Toledo (589), the Photian controversy, Florence (1439), Nerses Shnorhali.
2. Verdicts and trace
Weighed under the source-proximity principle: Scripture first, then the father tiers T1–T4.
3. Post-750 development
4. Overall verdict
T1: universal consensus, Scripture-grounded; all nine agree. T2: Scripture states procession from the Father; the fathers split East/West, and the creed’s 381 text lacks filioque. On T2 the Orthodox and Oriental Orthodox fit Scripture best; Western traditions follow Augustine’s strand.
5. Verification status
Florence, Toledo, Dositheus, AC I, WCF II.3 and the Orthodox Creed’s trinitarian article are cited from standard editions, not rechecked here (Art. V and 1689 2.3 standard; Art. I/V text available in the cached Articles).
