Apologists are prone to commit certain mistakes. In trying to win arguments with particular opponents, they sometimes mistakenly take over the assumptions of their adversaries. Exaggerating the powers of reason, some try in vain to demonstrate mysteries of faith such as the Trinity and the Incarnation. Others, as I have mentioned, make Christianity uninteresting by minimizing the element of mystery. I am convinced that it is best not to conceal the offense–the scandal, if you like–of the God who died on the Cross.
