But as Celsus next mentions the case of the Clazomenian, subjoining to the story about him this remark, “Do they not report that his soul frequently quitted his body, and flitted about in an incorporeal form? And yet men did not regard him as a god,” we have to answer that probably certain wicked demons contrived that such statements should be committed to writing (for I do not believe that they contrived that such a thing should actually take place), in order that the predictions regarding Jesus, and the discourses uttered by Him, might either be evil spoken of, as inventions like these, or might excite no surprise, as not being more remarkable than other occurrences.
But my Jesus said regarding His own soul (which was separated from the body, not by virtue of any human necessity, but by the miraculous power which was given Him also for this purpose): “No one takes my life from Me, but I lay it down of Myself. I have power to lay it down, and I have power to take it again.” For as He had power to lay it down, He laid it down when He said, “Father, why have You forsaken Me? And when He had cried with a loud voice, He gave up the ghost,” anticipating the public executioners of the crucified, who break the legs of the victims, and who do so in order that their punishment may not be further prolonged.
And He “took His life,” when He manifested Himself to His disciples, having in their presence foretold to the unbelieving Jews, “Destroy this temple, and in three days I will raise it up again,” and “He spoke this of the temple of His body;” the prophets, moreover, having predicted such a result in many other passages of their writings, and in this, “My flesh also shall rest in hope: for You will not leave my soul in hell, neither will You suffer Your Holy One to see corruption.”
