Karl Barth once described Calvin as 'a cataract, a primeval forest, a demonic power.' Goodloe doesn't disagree but finds, like Barth, that one could profitably spend a lifetime there. The piece reads Calvin on church unity for what he still has to teach a fragmenting PCUSA.
In 1943 Princeton Theological Seminary required apologetics. The next year, it dropped from the curriculum entirely. Dembski traces how rational defense of the Christian faith, once taken for granted as a Christian duty, became theologically suspect, and what the seminary's loss has cost the church.
Sola Scriptura, Solus Christus, Sola Gratia, Sola Fide, Soli Deo Gloria: the five Solas were the Reformers' refusal to compromise. Poteet examines what's been lost when contemporary liberalism quietly trims them, and how the church might restore the lines the Reformers thought load-bearing.
Centrifugal force in physics pushes a body away from the center. Mills uses Buechner's lexicon entry on sin (also centrifugal) to argue that theological boundaries do for the church what asphalt does for a car: not constrict, but keep us from flying off the road into wreckage.
John Spong rejects monotheism, the incarnation, the Trinity, and the atonement, then claims to be a Christian. Cyre asks what content actually distinguishes Christian faith from anything else, and walks through Paul, Athanasius, and the Reformers for the kind of answer Spong's question demands.
