The A's Have It: Argument Culture, Adiaphora & Atonement Theories

What is up, Theology Nerds! This week Bo and I kicked off our Theological Dictionary of 2026—26 letters for 26, pairing theological concepts with cultural commentary. We dove into the A's: argument culture, adiaphora, and atonement. We started with Deborah Tannen's 1997 book The Argument Culture and marveled at how she thought things were bad then—30 years before algorithms and 24-hour news cycles turned us all into gladiators. Then we explored adiaphora, that beautiful old Greek concept of "indifferent things"—matters not essential to salvation—as a potential antidote to our zero-sum cultural warfare. Tillich's wedding ring analogy made an appearance, and Bo brought the fire with Bonhoeffer's insistence that the Jewish question was absolutely not adiaphora in Nazi Germany. Context matters, folks. We landed on atonement as our test case: I want to call theories of atonement adiaphora because Scripture isn't crystal clear on mechanics, but there's this one group that insists PSA is the gospel. We unpacked six major theories, got into some Tillich, Bonhoeffer, Keith Ward, and Frank Tupper, and Bo may have gently suggested that penal substitutionary atonement is the least compelling of the bunch. Next week: B is for belonging, with baptism and bipartisan politics as our test cases. See you in Valhalla!

⁠ONLINE CLASS: The Rise of the Nones⁠⁠⁠⁠⁠⁠⁠⁠

One-third of Americans now claim no religious affiliation. That's 100 million people. 

But here's what most church leaders get wrong: they're not all the same. Some still believe in God. Some are actively searching. Some are quietly indifferent. Some think religion is harmful. 

Ryan Burge & Tony Jones have conducted the first large-scale survey of American "Nones", which reveals 4 distinct categories—each requiring a different approach. Understanding the difference could transform everything from your ministry to your own spiritual quest.
