And because you are sons, God has sent forth the Spirit of his Son into your hearts, crying,
Abba, Father.
All Commentaries on Galatians 4:6 Go To Galatians 4
Augustine of Hippo
AD 430
There are two words that he has set down so that the former may be interpreted by the latter, “for Abba” means the same as “Father.” Now we see that he has elegantly, and not without reason, put together words from two languages signifying the same thing because of the whole people, which has been called from Jews and Gentiles into the unity of faith.
