Historical evidence for Jesus Christ and His resurrection is presented.
Part 1 summarizes the Biblical account of the crucifixion, burial and resurrection of Jesus Christ.
In part 2, Chris White gives an overview of the ancient historical sources outside the Bible for the life and deeds of Jesus Christ. Attention is given to Tacitus, Lucian, Pliny the Younger, Thallus, the Talmud and Josephus.
The letters of Paul are discussed in Part 3. Paul was an enemy of early Christians until the risen Christ appeared to him. He then became a dedicated believer who travel throughout the Roman empire to preach Christ. He personally knew some of Christ’s family and disciples. Sceptics universally accept Paul’s letters to the Galatians and to the Corinthians as authentic. Paul’s letters provide the earliest written records of the resurrection of Christ.
In part 4, Dr. William [Lane] Craig analyzes the historical facts regarding the crucifixion, burial and resurrection of Jesus Christ. There are three facts accepted by the majority of historians. 1. The tomb of Christ was found empty. 2. Groups of people, including sceptics and enemies, believed that they saw the risen Christ. 3. The disciples came to believe that Christ rose from the dead even though they were predisposed to believe otherwise. The disciples believed so strongly in the resurrection that they were willing to endure death rather than recant their testimony. Based on these facts, Christians are justified in believing in the resurrection of Christ, and also his message of salvation.
