There was once in Paris, says Boccaccio, a brave and good merchant named Jean de Civigny, who did a great trade in drapery, and was connected in business with a neighbour and fellow-merchant, a very rich man called Abraham, who, though a Jew, enjoyed a good reputation.Jean de Civigny, appreciating the qualities of the worthy Israelite; feared lest, good man as he was, his false religion would bring his soul straight to eternal perdition; so he began to urge him gently as a friend to renounce his errors and open his eyes to the Christian faith, which he could see for himself was prospering and spreading day by day, being the only true and good religion;whereas his own creed, it was very plain, was so quickly diminishing that it would soon disappear from the face of the earth.The Jew replied that except in his own religion there was no salvation, that he was born in it, proposed to live and die in it, and that he knew nothing in the world that could change his opinion.Still, in his proselytising fervour Jean would not think himself beaten, and never a day passed but he demonstrated with those fair words the merchant uses to seduce a customer, the superiority of the Christian religion above the Jewish; and although Abraham was a great master of Mosaic law, he began to enjoy his friend's preaching, either because of the friendship he felt for him or because the Holy Ghost descended upon the tongue of the new apostle; still obstinate in his own belief, he would not change.The more he persisted in his error, the more excited was Jean about converting him, so that at last, by God's help, being somewhat shaken by his friend's urgency, Abraham one day said--"Listen, Jean: since you have it so much at heart that I should be converted, behold me disposed to satisfy you; but before I go to Rome to see him whom you call God's vicar on earth, I must study his manner of life and his morals, as also those of his brethren the cardinals; and if, as I doubt not, they are in harmony with what you preach, I will admit that, as you have taken such pains to show me, your faith is better than mine, and I will do as you desire; but if it should prove otherwise, I shall remain a Jew, as I was before; for it is not worth while, at my age, to change my belief for a worse one."Jean was very sad when he heard these words; and he said mournfully to himself, "Now I have lost my time and pains, which I thought I had spent so well when I was hoping to convert this unhappy Abraham; for if he unfortunately goes, as he says he will, to the court of Rome, and there sees the shameful life led by the servants of the Church, instead of becoming a Christian the Jew will be more of a Jew than ever." Then turning to Abraham, he said, "Ah, friend, why do you wish to incur such fatigue and expense by going to Rome, besides the fact that travelling by sea or by land must be very dangerous for so rich a man as you are? Do you suppose there is no one here to baptize you? If you have any doubts concerning the faith I have expounded, where better than here will you find theologians capable of contending with them and allaying them? So, you see, this voyage seems to me quite unnecessary: just imagine that the priests there are such as you see here, and all the better in that they are nearer to the supreme pastor.If you are guided by my advice, you will postpone this toil till you have committed some grave sin and need absolution; then you and I will go together."But the Jew replied--
"I believe, dear Jean, that everything is as you tell me; but you know how obstinate I am.I will go to Rome, or I will never be a Christian."Then Jean, seeing his great wish, resolved that it was no use trying to thwart him, and wished him good luck; but in his heart he gave up all hope; for it was certain that his friend would come back from his pilgrimage more of a Jew than ever, if the court of Rome was still as he had seen it.
