ACC ~ Galatians 4 v5b

OUR SONSHIP BY ADOPTION, HIS BY NATURE. AUGUSTINE: He says “adoption” so that we may clearly understand that the Son of God is unique. For we are sons of God through his generosity and the condescension of his mercy, whereas he is Son by nature, sharing the same divinity with the Father. EPISTLE TO THE GALATIANS 30 [1B.4.4-5].
