The public mind has of late been much agitated by the question of Sunday observance. We do not mean now to debate that point upon its merits, nor is it the least necessary for our present argument that we should do so. Every one, we are certain, wishes that the Lord's day should be properly and decently observed. There are differences of opinion, however, regarding the latitude which should be allowed--one party being in favour of a total cessation from work, and founding their view upon the decalogue; whilst the others maintain that, under the Christian dispensation, a new order of things has been established. There has been a good deal of discussion upon this topic, and the practical subject of dispute has been, whether railway trains should be permitted to run upon the first day of the week. On that head we shall say nothing; but we maintain that both parties are alike interested in having the limits of the Sunday accurately and distinctly declared. Some observance, whatever be its limit, is clearly due to the holy day, whether men hold it to be directly of divine ordinance, or to have been set apart for divine worship by ecclesiastical and conventional authority. By the present arrangement, the feelings of both parties are outraged. Sabbath or Sunday--call it which you will--has been changed by the Town Council, and is not the same as before. It is easy to say that this is quibbling, but in reality is it so? Can the Town Council compel us to accept any day they may please to nominate instead of Sunday, and consecrate Wednesday, for example, as that which is to be dedicated to pious uses? We repeat that this is but a question of degree. No authority, at least no such authority as that of a body of local magistrates, can dovetail the Sabbath by making it begin earlier and end later than before. There are stringent ancient Scottish statutes, some of them not altogether in desuetude, against Sabbath desecration, and how are these now to be interpreted or enforced? No true Sabbatarian can support the present movement. His case is irretrievably lost if he acquiesces in the change; for the day has unquestionably been violated--and it may be violated as well in a minute as in an hour. Those who take the other view cannot fail to be equally offended. The order which they keenly advocate and maintain has been wantonly broken and destroyed. The limits of Sunday are annihilated. Men do not know when it commences or when it ends, and they may be gaming when they ought to be at prayers. Churches and congregations of every kind have a common interest in this. The individuality of the day must be supported, and there must be no doubt, and no loophole left for cavillers to carp at its existence.
