Celsus, as reported by Origen, literally accuses the actions of the cult for secrecy. From what I quoted by Origen earlier:Giuseppe wrote: ↑Sat Mar 30, 2024 9:04 pmBut the actions of the cult are not the object of the accusation. Celsus accuses "often" the Christian doctrine of being secret. Which virtually put in doubt the his own certainty about the official version (earthly crucifixion in primis).GakuseiDon wrote: ↑Sat Mar 30, 2024 2:46 pmThe pagan Caecilius accuses Christians of being secretive about their rites
The first point which Celsus brings forward, in his desire to throw discredit upon Christianity, is, that the Christians entered into secret associations with each other contrary to law...
After this, Celsus proceeding to speak of the Christians teaching and practising their favourite doctrines in secret, and saying that they do this to,some purpose, seeing they escape the penalty of death which is imminent...
Moreover, since he frequently calls the Christian doctrine a secret system (of belief), we must confute him on this point also, since almost the entire world is better acquainted with what Christians preach than with the favourite opinions of philosophers... And yet the mystery of the resurrection, not being understood, is made a subject of ridicule among unbelievers. In these circumstances, to speak of the Christian doctrine as a secret system, is altogether absurd. But that there should be certain doctrines, not made known to the multitude, which are (revealed) after the exoteric ones have been taught, is not a peculiarity of Christianity alone...
I honestly don't know how you get to "Celsus is very close to put implicitly in doubt the historicity of Jesus is when he raises the accusation that 'the doctrine is secret".
