jan 1, 250 - Origen's "Against Celsus"

Description:

Against Celsus (Greek: Κατὰ Κέλσου; Latin: Contra Celsum), preserved entirely in Greek, was Origen's last treatise, written in the mid-third century CE. It is an apologetic work defending Christianity against the attacks of the pagan philosopher Celsus. In 178 CE(?), Celsus had written a polemic entitled "On the True Word," in which he had made numerous arguments against Christianity. Origen wrote his response refuting seriatim Celsus' arguments.
