Benjamin Rush to Richard Price
15 Oct. 178522 Apr. 1786Letters 1:371, 385--86[15 Oct. 1785]
I took the liberty of publishing, with your name, your excellent letter on the test law of Pennsylvania. It has already had a great effect on the minds of many people, and I doubt not will contribute more than anything to repeal that law. Dr. Franklin, who has succeeded Mr. Dickinson as our governor, has expressed his surprise at the continuance of such a law since the peace, and we hope will add the weight of his name to yours to remove such a stain from the American Revolution.
[22 Apr. 1786]
I am very happy in being able to inform you that the test law was so far repealed a few weeks ago in Pennsylvania as to confer equal privileges upon every citizen of the state. The success of the friends of humanity in this business should encourage them to persevere in their attempts to enlighten and reform the world. Your letter to me upon the subject of that unjust law was the instrument that cut its last sinew.
