It seems that ministers in Maine cannot agree any better on the question as to how Sunday should be regarded, than ministers in Michigan. A correspondent sends us the abstracts of two sermons preached on the same Sunday recently, in two churches in the city of Portland. Mr. Buck, of Park street church, took the ground that the Sunday of Christendom had nothing to do with the Jewish Sabbath; that the term Sabbath was not applied to it till the 17th century; that there is no divine command for it; that it grew up in the practice of Christians from complex reasons, in the development of a natural want; that it is not promoted by superstitions and burdensome ceremony; and that “we should seek its best and highest uses;—at church if we are persuaded in our own minds, in the Sunday-school, in social intercourse, in riding, in the fields, on the waves, or in the stillness of private meditation.” On the other hand, Mr. Day of Chestnut street church would enforce the Sunday with all the thunders of Sinai. He said that the efforts to “modernize” the day were in violation of the “moral law,” closing with the following words:— “We wish now to say that this whole question is a moral question which you should take home to your consciences. Here is God’s moral law. Every commandment of that law is sacred. He who breaks one of them is guilty of an immorality. Christ made no discrimination in these commandments, but taught that whoever offended in one was guilty of the whole. If it is an immorality to break the seventh, it is immoral to violate the fourth. Whoever violates the Sabbath is an immoral man. The man who goes on Sunday excursions is an immoral man. The man who drives on the street on Sunday for pleasure is an immoral man. The man who buys and reads newspapers on Sunday is an immoral man. No man can break one of God’s commands and continue in so doing and be moral.” According to Mr. B., Mr. D. is ceremonious and superstitious. And according to Mr. D., Mr. B. is an immoral man. Until these doctors can agree, what line of action do they expect to bring the masses to?
