Not too long ago I was in a discussion with a fellow apologist. We were discussing several different controversial topics in Christianity (age of the universe, Calvinism vs. Arminianism, and God's attributes). After a while he made a very strange statement. He told me that these discussions about science, philosophy, and theology weren't really important to apologists and only served to divide and cause unbelievers to run from Christ.
He took the position that apologists really only needed to defend the truth of the resurrection of Jesus Christ from the dead to establish the truth of Christianity. His main support for that claim was that no other worldview can accommodate the resurrection of Jesus, so if it can be shown to be an historical event, all other worldviews are eliminated from the possibility of being true.
