Thank you JohnD. I am reading Bahnsen’s work, “Presuppositional Apologetics”, where he takes the position that to argue/debate with an unbeliever from any other viewpoint than the presupposition of the authority of Scripture is an exercise in futility. Dr. Casey made this point above:
In particular, when our arguments are addressed to particular audiences, we are justified in taking their positions as starting points that do not need to be argued for.
How can we accept the presuppositions of the unbeliever as a starting point, but not accept the presupposotions of the unbeliever as a starting point…that is, only accepting the presupposition of the authority of Scripture as the starting point? I’m interested in yours and Dr. Casey’s response. Thanks.
