It is amusing to compare this letter written in America to the President of Yale College with what Franklin had previously written to Madame Brillon, when she objected to the marriage of her daughter to William Temple Franklin partly on the score of religious incompatibility: "These are my ideas. In each Religion, there are certain essential things, and there are others that are only Forms and Modes; just as a loaf of Sugar may happen to be wrapped up in either brown, or white or blue Paper, tied up with either red or yellow hempen or worsted twine. In every instance the essential thing is the sugar itself. Now the essentials of a good Religion consist, it seems to me, in these 5 Articles viz." Then ensues a statement of practically the same fundamental tenets as those that he afterwards laid before Ezra Stiles; except that, when he wrote to Madame Brillon, he was not certain whether we should be rewarded or punished according to our deserts in this life or in the life to come. He then adds: "These Essentials are found in both your Religion and ours, the differences are only Paper and Twine." Dr. Priestley, in his _Autobiography_, laments that a man of Dr. Franklin's general good character and great influence should have been an unbeliever in Christianity, and should also have done as much as he did to make others unbelievers. Franklin acknowledged to this friend that he had not given as much attention as he ought to have done to the evidences of Christianity, and, at his request, Priestley recommended to him several books on the subject, which he does not seem to have read. As Priestley himself rejected the doctrines of the Trinity, the Atonement, Original Sin and Miraculous Inspiration, and considered Christ to be "a mere man," though divinely commissioned and assisted, his fitness for the office of winning Franklin over to Christianity might well have been questioned. He belonged to the same category as Dr. Richard Price, that other warm friend of Franklin, who came into Franklin's mind when Sir John Pringle asked him whether he knew where he could go to hear a preacher of _rational_ Christianity.
