There is an intimate connection between loose religious views and the non-observance of the Sabbath. Skeptics are not friendly to the Sabbath as a class. It is an institution they inveigh against with much spirit. No doubt the change going on in Benjamin's opinions had much to do with his ceasing to attend public worship.
Fifteen years afterwards, when Benjamin was fully established in business in Philadelphia, his parents became very anxious about his skeptical ideas, and wrote to him about it. Their letter is not preserved, but we have his in reply, which, while it confirms the fact, shows him to be more reverent and thoughtful than they feared. It is, also, evidence of a filial regard for his father and mother that is always as beautiful as it is honorable. We furnish the letter below:
"PHILADELPHIA, April 13, 1738.
"Honored Father,—I have your favors of the 21st of March, in which you both seem concerned lest I have imbibed some erroneous opinions. Doubtless I have my share, and when the natural weakness and imperfection of human understanding is considered, the unavoidable influence of education, custom, books, and company, upon our ways of thinking, I imagine a man must have a good deal of vanity who believes, and a good deal of boldness who affirms, that all the doctrines he holds are true, and all he rejects are false. And, perhaps, the same may be justly said of every sect, church, and society of men, when they assume to themselves that infallibility which they deny to the pope and councils.
"I think opinions should be judged of by their influences and effects; and if man holds none that tend to make him less virtuous or more vicious, it may be concluded he holds none that are dangerous,—which, I hope, is the case with me.
"I am sorry you should have any uneasiness on my account, and, if it were a thing possible for one to alter his opinions in order to please another's, I know none whom I ought more willingly to oblige in that respect than yourselves. But, since it is no more in a man's power to think than to look like another, methinks all that should be expected from me is to keep my mind open to conviction; to hear patiently, and examine attentively, whatever is offered me for that end; and, if after all I continue in the same errors, I believe your usual charity will induce you rather to pity and excuse than blame me; in the mean time your care and concern for me is what I am very thankful for.
"My mother grieves that one of her sons is an Arian, another an Arminian; what an Arminian or an Arian is, I can not say that I very well know. The truth is, I make such distinctions very little my study. I think vital religion has always suffered when orthodoxy is more regarded than virtue; and the Scriptures assure me that at the last day we shall not be examined what we thought, but what we did; and our recommendation will not be that we said, Lord! Lord! but that we did good to our fellow-creatures. See Matt. xx.
"As to the free masons, I know no way of giving my mother a better account of them than she seems to have at present (since it is not allowed that women should be admitted into that secret society). She has, I must confess, on that account, some reason to be displeased with it; but, for any thing else, I must entreat her to suspend her judgment till she is better informed, unless she will believe me when I assure her that they are in general a very harmless sort of people, and have no principles or practices that are inconsistent with religion and good manners.
"B. FRANKLIN."
His sister also, later on, in her great anxiety for his spiritual welfare, wrote to him, and he replied as follows:
