To mark the 500th anniversary of the Protestant Reformation, a fresh Christian confession has been written to accentuate and celebrate theological unity among Protestants of diverse traditions. “A Reforming Catholic Confession” (RCC) was posted online just days ago. When asked to join an initial group of signatories months ago, I eagerly read the confession and happily signed. Now that it’s posted I invite you to read it and consider adding your signature here.
The RCC is clear about the Gospel, robustly trinitarian, and “catholic” in all the ways I seek to be catholic myself—without apologizing for my place within the Protestant tradition. The rationale for the RCC is explained in some detail on the website, including the following samplings about Protestant “catholicity”:
 The Protestant Reformers believed they were contending for “the faith that was once for all delivered to the saints” (Jude 3) and recovering the gospel that some were “so quickly deserting” (Gal. 1:6). They therefore believed their efforts to be both catholic and evangelical, that is, on behalf of the whole church and for the sake of the integrity of the gospel, particularly the singularity and sufficiency of Christ’s person and saving work (solus Christus). […]
 … While we regret the divisions that have followed in [the Reformation’s] wake, we acknowledge the need for the sixteenth-century Reformation, even as we recognize the hopeful possibilities of the present twenty-first century moment. Not every denominational or doctrinal difference is a division, certainly not an insurmountable one. We dare hope that the unity to which the Reformers aspired may be increasingly realized as today’s “mere” Protestants, like Richard Baxter’s and C. S. Lewis’s “mere Christians,” joyfully join together to bear united witness to the gospel of Jesus Christ and to its length, depth, breadth, and width – in a word, its catholicity. We therefore aim to celebrate the catholic impulse that lies at the heart of the earlier Reformation even as we hope and pray for ever greater displays of our substantial unity in years to come.
 “Is Christ divided?” (1 Cor. 1:13). Various sixteenth-century Protestant groups – including Lutheran, Reformed, Anglican, and some Anabaptists – produced confessions that not only demarcated their respective identities but also, and more crucially, established their catholic bona fides. In view of their catholic credentials, the common notion that Protestants are theological innovators who are hopelessly divided over doctrine because of a lack of centralized authority is an unwarranted caricature. On the contrary: as mere Protestants, we all acknowledge the Triune God of the gospel and the gospel of the triune God, including the supremacy of the Lord Jesus Christ and the biblical testimony about him. While we continue to disagree about the particular form and content of certain doctrines, we together affirm God’s Word as the singular and ultimate authority to which we must all submit our respective interpretations for judgment. Our interpretive disagreements must therefore be viewed in the context of our even greater agreements about Scripture. It is in this spirit, with hope and prayer, that we together confess our common faith.
What I appreciate about the RCC, and I would not have signed it otherwise, is that it makes no attempt to bash, caricature, or slight brothers and sisters from the Roman Catholic and Eastern Orthodox traditions of faith. I don’t believe it will harm ecumenical dialogue or partnerships in mission with non-Protestants. In fact, perhaps it will galvanize both, tamping down fears about compromise by articulating a generous, catholic center. Drawing confessing Protestants around a shared theological center is the goal, and I believe the RCC does that admirably.
For instance, here’s the article on Baptism and the Lord’s Supper. Anyone who knows anything about the Reformation, or the subsequent splintering of Protestant factions, knows how controversy and disagreement swirl around these.
That these two ordinances, baptism and the Lord’s Supper, which some among us call “sacraments,” are bound to the Word by the Spirit as visible words proclaiming the promise of the gospel, and thus become places where recipients encounter the Word again. Baptism and the Lord’s Supper communicate life in Christ to the faithful, confirming them in their assurance that Christ, the gift of God for the people of God, is indeed “for us and our salvation” and nurturing them in their faith. Baptism and the Lord’s Supper are physical focal points for key Reformation insights: the gifts of God (sola gratia) and the faith that grasps their promise (sola fide). They are tangible expressions of the gospel insofar as they vividly depict our dying, rising, and incorporation into Jesus’ body (“one bread … one body” – 1 Cor. 10:16-17), truly presenting Christ and the reconciliation he achieved on the cross. Baptism and the Lord’s Supper strengthen the faithful by visibly recalling, proclaiming, and sealing the gracious promise of forgiveness of sins and communion with God and one another through the peace-making blood of Christ (1 Cor. 11:26; Col. 1:20).
That’s a confession I can make. Even as I’m aware that Protestants of different traditions would nuance this statement, or emphasize certain parts in keeping with their liturgical traditions, I hope it’s a center around which we can celebrate the feast.
