• What a Baltimore Ravens helmet teaches us about the importance of truth
• What happens to Christians when they go off to university?
• The 2007 study on attitudes of American professors to evangelical Christians
• Authors: Who wrote the gospels?
• Bias: Did the bias of the authors cause them to distort history?
• Contradictions: What about the different descriptions of events in the gospels?
• Dating: When were the gospels written?
• Eyewitnesses: Do the gospel accounts go back to eyewitness testimony?
