Christian apologist/attorney, Craig Parton, has written a very fine introduction concerning an evidence-based approach to analyzing the Gospel account of Christ.
The first few chapters describe Mr. Parton's own personal theological journey from Evangelicalism to Confessional Lutheranism. Mr. Parton admires certain facets of Evangelicalism, including the love for Scripture and the interest in engaging with those from different theological backgrounds. But he also notes that there is often in Evangelicalism a strong emphasis on the works of the believer that, ironically, put the cross and works of Jesus not always completely away but, so to speak, on a shelf to the side. It is almost as if the message is: "You believers know about salvation and God's grace shown to you which is an early fundamental of faith, but the focus now throughout your life is primarily on how you will demonstrate your daily dedicated works in spiritual matters like reading, attending conferences, doing programs, learning advanced techniques, studying how to be better parents, etc." Mr. Parton is not suggesting (and neither am I) that good works and learning more about the Word are not crucial features of a believer's life. But believers, of course, sin daily and their works must not be the ultimate source of their identity and comfort. The identities of believers is found in the works and profound love of the incomparable Jesus Christ. This emphasis puts Biblical concepts like humility, confession, forgiveness and peace at the center of the Christian's life. This sustained priority on Jesus' life and on the cross is what makes Lutheranism Lutheranism! Mr. Parton shows how this Christocentric focus in Lutheran theology is helpful in the field of apologetics because Jesus' life, death and resurrection are historical events that have been recorded in Scripture. Using recognized methods employed by scholars in investigating ancient documents which chronicle historical events, Mr.Parton demonstrates that the Gospels provides reliable evidence/information concerning Christ. Furthermore, there are more early extant copies of Scripture than any other literary works of antiquity, by far. The point here is not missed, there are scholars of literature and history at major universities who believe "as a fact" regarding the prior existence of persons and events with far less documentary support than the Gospels concerning the historic person...Jesus! I so appreciate Mr. Parton's book and I pray you will as well. May God grant His Church grace to keep Christ at the center, and may God use the approach in this book to help those who are "dead in their trespasses and sin" to see the incredible uniqueness of the Bible, and then lead them to the reading/hearing of the Word which, by the power of the Spirit, brings new life!
