No one would dare to suggest that C. S. Lewis’s Mere Christianity is anything less than a brilliant explanation and defense of the Faith. But as robust, wise and ardent as it is, still it is incomplete. It begins our banquet at the table of the Lord, but doesn’t take us all the way to the final course.

That is what Dwight Longenecker’s new book, More Christianity, does. It fills our plates with the fullness of the Christian Faith found only in the Catholic Church. Lest someone think Longenecker is presuming to piggyback or cash in on Lewis’ work, or to set himself up as Lewis’ successor, that is not the case. What he does–and does brilliantly–is present the doctrine of the Church with succinct explanations of topics that arise in Catholic/Protestant discussion: the Marian dogmas, the papacy, the Mass, purgatory, the communion of saints, the rosary and more.

In Longenecker’s skilled hands, More Christianity rounds out the meal so deliciously served up by Lewis in Mere Christianity.
