What can we add to God’s mercy to be saved? The Reformers broke with the Roman Church when they answered that Christians are justified by faith alone. But evangelicals no longer seem certain about that keystone of faith. In Faith Alone, a Gold Medallion finalist and Evangelical Book Club main selection, R.C. Sproul discerns a softening of the doctrine of justification and explains why Christians must return to the biblical, Reformation view. He provides biblical evidence and theological reasons why Protestantism and Roman Catholicism divided in the first place, and why that division remains an uncrossed chasm.
