The Catholic archbishop slipped into an obvious self-contradiction; for he on one hand sanctified the authors of the four gospels and held them above lying while, on the other hand, he admitted to the Imam that they did tell lies about Christ (a.s.). Then the Imam (a.s.) goes to debate the High Rabbi, scholar of the Jews, to prove the prophethood of (S) from the previously revealed divine testaments, after which he follows with a very logical debate.
Having argued with him that one of the requirements of a Prophet was to perform something all other creation are unable to perform, he asked him about the reason why they, the Jews, refrained from believing into the miracles of all prophets other than Moses (a.s.) son of Imran (Amram), and the High Rabbi answered him saying, "We cannot admit the prophethood of any who professes prophethood except after bringing us knowledge similar to that brought by Moses." Ar-Ridha’ (a.s.) said to him, "Then how come you admitted the prophethood of other prophets who preceded Moses (a.s.) who did not split the sea, nor cleave the stones so that twelve springs would gush forth from it, nor took their hands out shining white as Moses did, nor did they turn a cane into a snake?!" It was then that the High Rabbi overcame his stubbornness, submitted to the argument, and admitted that any supernatural act beyond human capacity was indeed a proof of prophethood.
The Imam (a.s.) asked him then about the reason why they did not believe in the prophethood of Jesus (a.s.) despite the fact that he brought forth miracles beyond human capacity such as bringing the dead back to life, healing those who were born blind and the lepers, and about the reason why they did not believe in the prophethood of Muhammad (S) despite his bringing an extra-ordinary miracle, that is, the Holy Qur'an while he was neither a scholar nor a writer.
The High Rabbi had no answer at all. Then came the turn of the Zoroastrian high priest whom the Imam debated depending on the priest's belief in the prophethood of Zoroaster. The Zoroastrian tells the Imam that Zoroaster brought them what no other man had ever brought them before.
"We did not see him," he continues, "but the stories of our ancestors told us that he legalized for us what no other person before made legal; so, we followed him." The Imam asked, "You believed in the stories which came to you about him, so you followed him, didn't you?" "Yes," he answered.
