Origen on the right of the Jews for self-dense being temporary

"It was impossible for Christians to follow the Mosaic law in killing their enemies or those who acted illegaly and were judged to be deserving of death [...] if you took away from the Jews of that time, who had their own political life and country, the power to go out against their enemies and to fight for their traditional customs, and to take life [...] the inevitable consequence would have been their complete and utter destruction [...] But the providence which long ago gave the law, but now has given the gospel of Jesus Christ, did not wish that the practices of the Jews should continue, and so destroyed their city and temple[...]" (Con. Cel. VII,26)

Origen on the continuity between the commandments of the law and of Jesus (Matt. 5:38-39)

"[...]it is written in the Lamentations of Jeremiah: 'It is good for a man when he bears a yoke in his youth, he will sit alone and in silence when he has taken it on himself. He will give a cheek to the man who smites him and shall be filled with reproaches.' The gospel, then, does not lay down laws in contradiction to the God of the law, not even if we interpret literally the saying about a blot on the jaw. And neither Moses nor Jesus is wrong. Nor did the Father forget when sent Jesus the commands which he had given to Moses. Nor did He condemn His own laws, and change His mind, and send His messenger for the opposite purpose." (Con. Cel. VII,25)
