In American culture, including the academy, there are actually very few unique objections to Christianity. It is helpful to understand six basic ones and recognize when someone is proclaiming a variation and then understand a humble but solid response.
Tim Keller, the author and pastor of Redeemer Church in New York City labels these objections as ‘defeaters.’ As academics of faith, I suggest we have a certain responsibility to be able to competently discuss these defeaters with both our students and colleagues.
