We speak with Gregg Allison and Chris Castaldo about their excellent book The Unfinished Reformation: What Unites and Divides Catholics and Protestants after 500 Years (Zondervan, 2016). Rev. Dr. Allison is Professor of Christian Theology at The Southern Baptist Theological Seminary in Louisville, Kentucky. Rev. Dr. Castaldo serves as Lead Pastor of New Covenant Church in Naperville, Illinois. We are driven to ask, Why are we accepted by God? In the final analysis, it must be Christ's person and work and his imputed righteousness to sinners. Salvation is by grace alone through faith alone. It depends solely on Christ and not anything we do.
