In the 2nd century CE a Roman author named Celsus wrote a book attacking the Christian movement, but when Christianity became the official religion of Rome Celsus' book was thoroughly suppressed, so no copies survived into modern times. Celsus was quoted extensively though by early Church Fathers who wrote books in response to his writings. This book is an attempt to reassemble Celsus' book based on the surviving quotations. It is impossible to know if Celsus' best arguments are represented here, or if his opponents only quoted his weaker arguments in order to more easily dismiss him, but either way it is still an interesting read.
