No doubt many will think, that at a time when the prevailing tendency is to disregard all sacred seasons, it were better not to say these things, but to leave men under an impression that the law of God requires the observance of the first day of the week, and sanctions calling that day the Sabbath. But this prevailing disregard of the day of rest, is an important reason for urging an examination of the foundation upon which the Sabbath rests. Common prudence, to say nothing of Christian sincerity, would require us, in such circumstances, to place the duty upon its true ground. If it will not stand there, it will stand nowhere. It is a dangerous experiment to encourage or connive at misconceptions in a point like this. And even if we felt assured that it would be right, we are fully convinced that it would be inexpedient. It is exceedingly dangerous to acknowledge an unsound principle, although it may promise to conduct us to desirable results, or, at the worst, to produce no bad effects. It ought to be remembered, that it was in apparently trivial and harmless points, that those false principles were allowed, which have infused their poison into the Romish and other apostate churches--a poison which, commencing with the extremities, has worked its way rapidly towards the vitals, and diffused its effects through the whole system. It is not, then, a matter of small moment. The most important and disastrous consequences may result from baptizing a day of human invention with a name which the Scriptures apply exclusively to one appointed of God.
