Origen of Alexandria, Against Celsus 1.69

After this, Celsus brings forward the discourse and the charges that some heresy levels as common faults of Christians, addressing them to everyone who draws near to the divine discourse, and he declares that God would never have a body like yours. We, on the other hand, confess that he took on a body by coming from a woman to dwell in human life, making it capable of human death. That is why, among other things, we also call him a great athlete: his human body was tested in the same way as every other human being in all respects, yet not as humans with sin, but in every way without sin. For it is perfectly clear to us that he committed no sin, nor was any deceit found in his mouth (1 Peter 2:22); and God handed him over, though he knew no sin, as a pure offering on behalf of all who had sinned. Then Celsus asserts that a body sown in such a way could not be God's body, just as you, Jesus, were sown. He concedes, however, that if, as it is written, he had been born, his body might somehow be more divine than most and be called God's body in some sense. But because he disbelieves the accounts written about his conception by the Holy Spirit and instead believes that he was sown by a certain Panther who corrupted the virgin, he concludes that such a body could not be God's. We have already said more about these matters above.
