What seminary did staples attend? Did he graduate? What specifically are his qualifications in this area that you place so much faith in?
The argument from authority is the weakest argument.
I read his book. He deals with dozens of passages in Scripture, and with dozens of arguments from apologists who deny the dogmas he is defending.
Nothing I have said about Staples’s book is based on his credentials. It’s all based on what’s actually in the book.
