Whoever in the community of Amsterdam could compose verses in Spanish, Portuguese, or Latin, sang or bewailed the martyrdom of the two Bernals. Was Spinoza's view correct that all these martyrs, and the thousands of Jewish victims still hounded by the Inquisition, pursued a delusion? Could the representatives of Judaism allow unreproved, in their immediate neighborhood, the promulgation of the idea that Judaism is merely an antiquated error?
The college of rabbis, in which sat the two chief Chachams, Saul Morteira and Isaac Aboab--Manasseh ben Israel was then living in London--had ascertained the fact of Spinoza's change of opinion, and had collected evidence. It was not easy to accuse him of apostasy, as he did not proclaim his thoughts aloud in the market-place, as Uriel da Costa had announced his breach with Judaism. Besides, he led a quiet, self-contained life, and associated little with men. His avoidance of the synagogue, the first thing probably to attract notice, could not form the subject of a Rabbinical accusation. It is possible that, as is related, two of his fellow-students (one, perhaps, the sly Isaac Naar) thrust themselves upon him, drew him out, and accused him of unbelief, and contempt for Judaism. Spinoza was summoned, tried, and admonished to return to his former course of life. The court of rabbis did not at first proceed with severity against him, for he was a favorite of his teacher, and beloved in the community on account of his modest bearing and moral behavior. By virtue of the firmness of his character Spinoza probably made no sort of concession, but insisted upon freedom of thought and conduct. Without doubt he was, in consequence, laid under the lesser excommunication, that is, close intercourse with him was forbidden for thirty days. This probably caused less pain to Spinoza, who, self-centred, found sufficient resource in his rich world of thought, than to the superficial Da Costa. Also, he was not without Christian friends, and he, therefore, made no alteration in his manner of life. This firmness was naturally construed as obstinacy and defiance. But the rabbinate, as well as the secular authorities of the community did not wish to exert the rigor of the Rabbinical law against him, in order not to drive him to an extreme measure, i. e., into the arms of the Church. What harm might not the conversion to Christianity of so remarkable a youth entail in a newly-founded community, consisting of Jews with Christian reminiscences! What impression would it make on the Marranos in Spain and Portugal? Perhaps the scandal caused by Da Costa's excommunication, still fresh in men's memories, may have rendered a repetition impracticable. The rabbis, therefore, privately offered Spinoza, through his friends, a yearly pension of a thousand gulden on condition that he take no hostile step against Judaism, and show himself from time to time in the synagogue. But Spinoza, though young, was of so determined a character, that money could not entice him to abandon his convictions or to act the hypocrite. He insisted that he would not give up freedom of inquiry and thought. He continued to impart to Jewish youths doctrines undermining Judaism. So the tension between him and the representatives of Judaism became daily greater; both sides were right, or imagined they were. A fanatic in Amsterdam thought that he could put an end to this breach by a dagger-stroke aimed at the dangerous apostate. He waylaid Spinoza at the exit from the theatre, and struck at the philosopher with his murderous weapon. But the latter observed the hostile movement in time, and avoided the blow, so that only his coat was damaged. Spinoza left Amsterdam to avoid the danger of assassination, and betook himself to the house of a friend, likewise persecuted by the dominant Calvinistic Church, an adherent of the sect of the Rhynsburgians, or Collectants, who dwelt in a village between Amsterdam and Ouderkerk. Reconciliation between Spinoza and the synagogue was no longer to be thought of. The rabbis and the secular authorities of the community pronounced the greater excommunication upon him, proclaiming it in the Portuguese language on a Thursday, Ab 6th (July 24th), 1656, shortly before the fast in memory of the destruction of Jerusalem. The sentence was pronounced solemnly in the synagogue from the pulpit before the open Ark. The sentence was as follows:
