In Epistolam D. Pauli Apostoli ad Galatas notae

4 Who gave himself for our sins, that he might deliver us from this present evil age, according to the will of God and our father.

5 To whom be glory forever and ever. Amen.

Paul, an Apostle.) Since God sent this envoy, he wants his voice to be heard through Paul.

Not from men.) There is a twofold calling: the immediate, like that of Paul from heaven, as he says here: not from men, nor through man, but through Jesus Christ. Where also a remarkable testimony of the Deity of Christ is to be observed. The other is mediate, when the Lord calls to the ministry through the Church and its ministers, whom He has instructed with the necessary gifts, Titus 1, verse 5. These are to be heard only insofar as they remain in the Prophetic and Apostolic doctrine.

Who gave himself for our sins.) He proposes the summary of the Gospel, about which the Galatians were to be taught, in the very greeting. What becomes our justice before God, namely, that Christ gave himself for our injustice.

According to the will of God and our father.) He opposes [this] to merits. Why does he rescue us? Not because of merit, but out of grace. Consolation: That the Gospel is an infallible testimony to us that God is not only our creator but also our father, John 20.

6 I wonder that you are so quickly, having deserted him who called you into the grace of Christ, transferring to another Gospel.

7 Which is not another: but some are disturbing you
