In the wide scope of his charities he had curious experiences, and one of these got to be known and quoted. A gentleman visited him and asked for a contribution to an old-established society known all the world over. Aaron inquired the name and objects of the society. "You have doubtless heard of it," replied the gentleman. "It is for the promotion of Christianity among the Jews." Aaron smiled as he said, "But, my dear sir, I am myself a Jew." "I am aware of it," said the gentleman, "and the reason I make the appeal is that you have been quoted to me as a man who has no narrow prejudices, and who in no sense of the word could be called dogmatic or prejudiced." "It is, then, a compliment you are paying me by asking me to contribute to a fund which is antagonistic to my race." "In your view antagonistic," observed the gentleman. "I see. Meaning that my view is not necessarily the right view." The gentleman nodded courteously. He was not a collector for the society, nor a paid officer, but a gentleman of means who, in a smaller way than Aaron, was also noted for his benevolence. "I cannot but consider the matter seriously," said Aaron thoughtfully, "for there can be no doubt of your sincerity. Still it occurs to me that if we were both equally sincere in our advocacy of objects of a similar nature it would be as well that we should pause and ask ourselves this question: Instead of endeavoring to convert Jews or Christians to a faith in which they were not born, would it not be better to employ ourselves in making those who call themselves Christians true Christians, and those who call themselves Jews true Jews?" "There is force in your argument," said the gentleman, "but it is no answer to my appeal for a contribution to the objects of my society." "Can you furnish me with particulars," Aaron then said, "of the working of the society?" "I have brought the papers with me, anticipating your request." Aaron looked over the printed books and papers handed to him, and made certain calculations upon paper. "I perceive," he said, "that you take credit to yourselves for making a certain number of conversions during the past five years, and that you have spent a great deal of money in these conversions. The number of conversions is very small, the amount of money expended very large. I have worked out the sum, and I see that each conversion has cost you nearly eleven thousand pounds. You find these wavering Jews very expensive?" "Very expensive," assented the gentleman, with a half-humorous sigh. "Well, my dear sir," said Aaron, "I will make a proposition to you. You are zealous in the furtherance of an object which you believe to be worthy, and I am zealous in the furtherance of an object which I believe to be worthy. I will write a check in contribution to your object on the understanding that you write a check for half the amount in contribution to mine. Do not be afraid; it is not for the promotion of Judaism among the Christians."
