The major theme of Paul’s letter to the Galatian churches can be summed up in the Latin phrases, Sola Gratia, Sola Fide, Solus Christus. To these may be added the remaining phrases of Sola scriptura and Soli Deo Gloria, known as the Five Solae (or Solas), Martin Luther’s five founding principles of the Reformation.

The typology of Galatians juxtaposes Abraham as the father of the faithful against that of the nation of Israel turning to a man-made idol through the topic of circumcision, an element of the Mosaic Law, though it did predate Moses.

The redemptive-historical context of the book is one that includes salvation by grace through faith in the work of Christ Jesus as the acceptable way of being reconciled to God, as opposed to the old way under the old covenant, that of submission to and placing oneself under the Mosaic Law as a means of salvation from sin, again represented by the message of some that one must also be circumcised as well as having faith in Christ. Historically, this notion was up-ended by God when he told Peter to preach the Gospel of grace through faith to the gentile believers in the house of Cornelius (Acts 10).

The central theme of the book is that nothing can add to the finished work of Christ Jesus on the cross in terms of our redemption, and is best reflected in my opinion by Galatians 2: 20:

“I have been crucified with Christ; and it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself up for me.”

The concepts expressed in this verse colour the entire letter. They include the concept of substitution (Jesus died for us, and it is by His faith that we live), inclusion (we have been and still are crucified with Christ), indwelling (though I live, it is not I but Christ living in me), and the love of God for us seen in God’s sacrifice of His own Son, and the Son’s love for us in that He sacrificed Himself. As the letter itself is unpacked, meanings and implications will become clear, and will be addressed as we go.
