Celsus said this quote

“ First, however, I must deal with the matter of Jesus, the so-called savior, who not long ago taught new doctrines and was thought to be a son of God. This savior, I shall attempt to show, deceived many and caused them to accept a form of belief harmful to the well-being of mankind. Taking its root in the lower classes, the religion continues to spread among the vulgar: nay, one can even say it spreads because of its vulgarity and the illiteracy of its adherents. And while there are a few moderate, reasonable, and intelligent people who interpret its beliefs allegorically, yet it thrives in its purer form among the ignorant. ”
