X. The power of custom, though sustained by ecclesiastical and civil enactments, and with corresponding forfeitures and penalties, ought not to prevent investigation and discourage reform in this important matter. When the claims of the original Sabbath are plainly presented, many seem to be convinced of their justness; but, at the same time, think that a general return to the observance of the seventh day is impracticable. They alledge that the custom of keeping the first day has been so long and so generally maintained--that it is so intimately wrought into the habits, calculations, and business of life--that it has received such explicit sanction from the civil powers, obedience thereto being required by the authority of the State, and the disobedient being subjected to civil pains and penalties--and that it is so often, ably, and pointedly vindicated by the first ministers, professors, and commentators in the popular churches, that it is in vain to expect a change, and that the cause of Sabbath-keeping is rather retarded than promoted by efforts to change the present custom. And it is highly probable that some, in view of these difficulties, forbear to give the subject a close investigation. But if the same views and modes of reasoning had been adopted in other cases, what would have become of the various reformations which are now established, and even triumphant? What would have become of the whole subject of _Protestantism_? There is nothing more impracticable in a Sabbath reform than in any other reform. In other cases, difficulties which at first seemed insurmountable, have given way to laborious, prayerful, and united efforts. And there is the same reason to believe that they will give way in this, if a proper zeal is once awakened, and the friends of the Sabbath are resolved to examine the subject, build on the foundation of truth, and persevere in their labors, with union and vigor, relying upon the protecting power and blessing of Israel's God. It is manifest that no earthly consideration should impede our investigation of this matter, that no array of opposition and discouragement should daunt us, and that no motives to sit still or pass along with the current of public opinion, if that be not founded in truth, should be suffered to influence us, and detain us in the wilderness of error. The cause of obedience is the cause of God, and we should steadfastly labor to promote it, and trust in him for ultimate victory.
