Judaism recognizes the freedom of religious convictions. Original, pure Judaism, therefore, contains no binding articles of belief, no symbolical books, by which the faithful were compelled to swear and affirm their incumbent duty. Judaism prescribes not faith, but knowledge, and it urges that its doctrines be taken to heart. In this despised religion everyone may think, opine, and err as he pleases, without incurring the guilt of heresy. Its right of inflicting punishment begins only when evil thoughts become acts. Why? Because Judaism is not revealed religion, but revealed legislation. Its first precept is not, "thou shalt believe or not believe," but, "thou shalt do or abstain from doing." "In the divinely-ordained constitution, state and religion are one. Not unbelief, false teaching, and error, but wicked offenses against the principles of the state and the national constitution are chastised. With the destruction of the Temple, _i. e._, with the downfall of the state, all corporal and capital punishment, as well as money fines, ceased. The national bonds were dissolved; religious trespasses were no longer crimes against the state, and religion, as such, knows no punishments." For those who seriously or jestingly had reported that Mendelssohn had separated from Judaism, he laid stress upon two points not wholly germane to his subject, viz., that the so-called ceremonial law of Judaism is likewise, indeed particularly, of divine origin, and that its obligatory character must continue "until it pleases the Supreme to abrogate it as plainly and publicly as it was revealed." The effect of this detailed apology was greater than Mendelssohn could have expected. Instead of defending himself he had come forward as an accuser, and in a manner at once gentle and forcible he had laid bare the hateful ulcers of the church and state constitution. Two authoritative representatives of the age pronounced flattering opinions upon him and the subject which he was discussing. Kant, who had already testified to his greatness of thought, wrote that he had read "Jerusalem" with admiration for its keenness of argument, its refinement, and cleverness of composition. "I consider this book the herald of a great reform, which will affect not alone your nation, but also others. You have succeeded in combining your religion with such a degree of freedom of conscience as was never imagined possible, and of which no other faith can boast. You have, at the same time, so thoroughly and clearly demonstrated the necessity of unlimited liberty of conscience in every religion, that ultimately our Church will also be led to reflect how to remove from its midst everything that disturbs and oppresses conscience, which will finally unite all men in their view of the essential points of religion."
