Chapter 23: On the Son; begotten not created or adopted
CHAPTER TWENTY-THREE. On the Son.
The Son is the second person in the most holy Trinity, the Logos of the Father by communication of the same deity which the Father has without origin, begotten from eternity from the Father.
We call Him Son neither by creation properly so called, because all things that were created were created through Him — John 1:3 — nor by adoption, because all who are adopted sons are adopted in Him — John 1:12; Ephesians 1:5-6 — but by generation, as Son by nature, having the whole divinity communicated from the Father — Micah 5:2. He is called Person in the same signification as the Father, because He is a subsistence, individual, incommunicable — John 1 — of living nature — John 5 — understanding — John 1:18 — willing — Matthew 11:27; John 5:21 — powerful — Philippians 3 — acting — John 5:17,19. And indeed a person in the most holy Trinity, that is divine, or, what is the same, that one and highest God, coessential with the Father and the Holy Spirit.
Latin
CAPUT VIGESIMUM TERTIUM, De FILIO. Filius est persona secunda in sacrosancta Trinitate, Logos Patris per communicationem eiusdem deitatis, quam Pater habet sine origine, ab aeterno a Patre genitus. Filium dicimus, neque per creationem proprie dictam, quia omnia per illum creata sunt quae creata sunt — Joh. I.3 — neque per adoptionem, quia omnes in illo adoptati sumus qui adoptati filii sumus — Joh. I.12; Eph. I.5-6 — sed per generationem, ut Filium natura, totam divinitatem a Patre communicatam habentem — Mich. V.2. Dicitur Persona eodem significatu quo Pater, quia est subsistens, individuum, incommunicabile — Joh. I — naturae viventis — Joh. V. — intelligentis — Joh. I.18 — volentis — Matth. XI.27; Joh. V.21 — potentis — Phil. III — agentis — Joh. V.17,19. Et quidem persona in sacrosancta Trinitate, hoc est divina, seu, quod idem est, unus et summus ille Deus, Patri et Spiritui sancto coessentialis.
