We had a wonderful year of studying the Protestant Reformation (September 2022 through May 2023) here at Redeemer Presbyterian Church in Austin, TX. Over the months we examined all of the key people and many of the significant events of the Reformation. Plus we had the opportunity to discuss and reflect on all the essential doctrines that emerged from this important time in history. Here is a short summary of the central doctrines of the Reformation:

  1. “By Scripture Alone” (Sola Scriptura): The Bible alone is the source of God’s revelation; it contains the Law, the Gospel, and principles for how we should live, worship and think (principium cognoscendi). At the Diet of Worms (1521) Martin Luther based his whole argument on the phrase, “My conscience is captive to the Word of God.” Thus, Sola Scriptura is commonly referred to as the “formal principle” of the Reformation (Isa. 40:8; Jn. 5:39, 10:35; 2 Tim. 3:14-17, Heb. 4:12-13).
  2. “By Christ Alone” (Solus Christus): Jesus Christ is the only name by which we may be saved. The gospel is exclusive, and only faith in Christ saves (Isa. 53:1-12; Jn. 14:6; 1 Tim. 2:5-7, Acts 4:12).
  3. “By Grace Alone” (Sola Gratia): God’s grace alone is the ground of our salvation, and this is received by faith alone. Without God’s grace no one would be saved (Ps. 31:1; Eph. 2:4-10; Tit. 2:11-14).
  4. “By Faith Alone” (Sola Fide): God-given faith is the only way to receive the imputed righteousness of Christ, which results in our justification. Luther noted, “faith is the receptive organ of justification.” Hence, the gift of faith is often referred to as the “material principle” of the Reformation. Moreover, Luther insisted that justification by faith is,“the article upon which the Church stands or falls” (justificatio est articulus stantis et cadentis ecclesiae). See the following Bible passages which clearly prove this point (Hab. 2:4; Rom. 1:16-17, 3:28; Eph. 2:8-9; Tit. 3:5-7).
  5. “Before the face of God” (Coram Deo): Christians are exhorted by the Bible to live all of life in the presence of God. This implies that there is no area of life where we do not have “business with God” (Negotium cum Deo). Christ is Lord over all (Prov. 15:3; Eph. 5:1-21; Col. 3:1-17).
  6. “To God Be the Glory” (Soli Deo Gloria): God alone is the proper recipient of our gratitude in the matter of salvation and the Christian life (1 Cor. 10:31; Tit. 3:5-7; 1 Pt. 4:10-11).
  7. “The Priesthood of Every Believer” (Communio Sanctorum): Every believer is exhorted by God to live-out the Christian life as a “holy venture” that pleases God (1 Pt. 2:9-10). Our sanctification and assurance of salvation are based solely upon the finished work of Jesus Christ on the Cross (Rom.  12:1-2; 1 Jn. 1:9, 5:13; 1 Pt. 2:21-25).
  8. “After Darkness, Light” (Post Tenebras Lux): This was the town motto of Geneva, Switzerland during the time of the Reformation. It reflects the wonderful deliverance from their former way of life that the local population came to feel as they lived by the doctrines of the Bible (Jn. 3:19-21 and 8:12; Eph. 4:17-32; Col. 1:13-14).
  9. “The Church reformed, always reforming” (Ecclesia Reformata, Semper Reformanda): This slogan does not mean that the Church is always seeking to be “in step” with modern contemporary culture. Instead, it means that the Church of Jesus Christ is always measuring its doctrine and practices by Holy Scripture and reforming it when necessary. Only in this way does the Church keep itself pure and fit for service unto the Lord (Rom. 12:1-2).  

Here is a picture of our intrepid classmates (minus a few individuals who were away on the final day):

Also, a few weeks prior several of us enjoyed a fun luncheon after class at Pok-E-Joe’s BBQ here in Austin. These kinds of informal gatherings allow us to continue talking about what we are learning, while also building good friendships.

Lastly, I’ll announce the details for next year’s class soon! We plan to resume our studies on Thursday, September 14th.
