An author mounts a detailed rebuttal to a popular historical outline that challenges Christian doctrines, presenting a structured pamphlet that defends religious belief and critiques the opponent's competence. He argues the historical work misstates biological theory by treating natural selection as the sole explanatory mechanism, misreads early Christian sources, and misunderstands Catholic doctrine, while also accusing the opponent of personal invective and of evading most substantive criticisms. The pamphlet organizes six principal charges, answers a few specific alleged mistakes by the author himself, defends the right of public reply, and contrasts secular optimism with traditional religious conviction.
