§ 01 — The Teaching

What the Church holds.

Scripture, the Councils, and the lived Liturgy — held together. These are the load-bearing points.

01Section 1

The Baptism of Christ (Mt 3:16-17) reveals the Father's voice, the Son in the waters, and the Spirit descending as a dove.
The Nicene-Constantinopolitan Creed safeguards the full divinity of the Son and Spirit alongside the Father.

02Section 2

Every service begins and ends with the Trinitarian doxology, glorifying Father, Son, and Holy Spirit.
Baptism, Chrismation, and the Eucharist immerse us into Trinitarian life as communion with God and one another.

03Section 3

Knowing God as Trinity means that love and relationship are at the heart of reality itself.
The Christian vocation is to reflect Trinitarian communion through self-giving love in the Church and the world.
