He is one of several writers named Celsus who appeared as opponents of Christianity in the second century; he is probably the Celsus who was known as a friend of Lucian, although some doubt this, because Lucian's friend was an Epicurean, and the author of the "True Discourse" shows himself a Platonist.
Celsus owes his prominence in the history of Christian polemics not so much to the pre-eminent character of his work, as to the circumstance that about the year 240 a copy of the work was sent to Origen by his friend Ambrosius, with a request to write a refutation of it.
Celsus took pains to make himself acquainted with the beliefs of his Christian contemporaries, and he is unquestionably conscious of his knowledge of Christianity.
