In The Unknown Sanctuary, written many years later, Pallière described what followed. The rabbi listened to him explain his doubts about becoming a Jew, and the rabbi acknowledged them all. He told Pallière that there was no duty on anyone's part to become a Jew, and that the anguish his mother might feel on being parted from her son was certainly not misplaced. He went On:
:We Jews have in our keeping the religion destined for the entire human race, the religion to which the Gentiles are subject and by which they are to be saved, as were our Patriarchs before the giving of the Law. Could you suppose that the true religion which God destines for all humanity is only the property of a special people? Not at all. His plan is much greater than that. The religion of humanity is no other than "Noachism," not because it was founded by Noah, but because it was through the person of that righteous man that God's covenant with humanity was made. This is the path that lies before your efforts, and indeed before mine, as it is my duty to spread the knowledge of it also.
Rabbi Benamozeg explained that the present non-Jewish religions acknowledged their origins in Judaism but were not prepared to admit that Judaism was still what it had always been, preferring to insist that the Jews should convert out of their ancestors' faith.
He expressed his indecision in letters to the rabbi, who replied at length with the aim of helping his pupil to face the challenges of the new position:
:If I understand you correctly, "Noachism" seems to you a far distant and superannuated thing, and you ask how after the passing of so many centuries of progress I can dream of taking you back to the foundations of worship that existed after the Flood. Is this possible? Yes it is, and I trust you will soon see that its future prospects likewise would not be possible if they had not also been present so far in the past.
:The "Noachic" religion is not a contrivance nor an invention. It is an established fact, discussed on every page of our Talmud, and our wise men generally admit that it is little known and much misunderstood.
There is some element of controversy over the teachings of Benamozegh. Rabbi Zvi Yehuda Kook z"l had a negative opinion of Benamozegh's attitudes which Rav Kook felt were too accommodating to Christianity, perhaps as a result of living in galut in a Catholic country without being sufficiently isolationist.
