Against Celsus Book 1

"Against Celsus Book 1" is an important book written by Origen of Alexandria, a Church Father, around 248 AD. The book is written in Greek and is a response to Celsus, a pagan philosopher who had criticized Christianity in his book "The True Word". Origen refutes Celsus' claims and defends Christian doctrine, which Celsus had called irrational. The book is also a defense of Christians who were being criticized by Celsus as uneducated and unpatriotic. The book is a significant work in Christian apologetics and sheds light on the early debates between Christians and pagans."
