1. It is said that the term _Sabbath_ signifies _rest_; therefore the first day, being commonly observed as a day of rest, may properly be called the Sabbath. In reply to this, it may be said, that when, by custom and common consent, any term is used to express a particular place or thing, it then becomes a proper name for that thing, and signifies only that thing to which it is applied. For instance, a _tabernacle_ means a place of worship. Yet, in New York, where this name is used to express a particular and well-known place of worship, it would be absurd and false to say you were at the _Tabernacle_, and mean the Church of the Messiah. So with the term Sabbath; although the word strictly means _rest_, yet after the Scriptures throughout the Old and New Testaments have used this term to express a particular rest, which occurred on the seventh day, it would be foolish and deceptive to speak of the Sabbath and mean the first day of the week. It may be farther said, that if this argument be good for calling the first day the Sabbath, and if the fact of its being a _rest_-day makes it the Sabbath, then may the Mohammedans properly call the _sixth_ day the Sabbath, and the fact that they rest upon that day makes it the Sabbath. Yes, and those Mexican Indians, whom Cortes found keeping the _fourth_ day, may properly call that day the Sabbath, and directly it is made such. Even those people in Guinea, whom Purchase describes as having a _rest_-day, but which, says he, "they observe not upon our Sunday, nor upon the Jews' Sabbath day, but hold it upon Tuesday, the _second_ working day of the week," may properly call that day the Sabbath, and straightway it becomes such. Are the observers of the first day ready to rest upon such ground for calling that day the Sabbath, or to continue to call it Sabbath when there is no better ground? We hope not. And we feel bound, as those who respect the Bible, and dare not charge the Author of that Book with folly in calling the seventh day only the Sabbath, to protest against such abuse of the language of Scripture. 2. The second reason frequently urged, is, that the first day _comes in the room_ of the seventh day, and may therefore properly be called the Sabbath. Aside from the fact that the Scriptures say _not a word_ about a substitution of the one day for the other, it may be said in reply, that if the argument be good, then the Lord's Supper may be called the _Passover_, and King Solomon may be called King _David_.
