The extensive operations in which you are engaged for the conversion of the world, render it in the highest degree important that you should not err on a question like this. If you are right, you ought to be very certain of it. Among the heathen, you are extending the observance of Sunday as a sacred day. If you are thus sowing the seeds of error instead of truth, the evils who can calculate? Hence you cannot too early begin to review your ground. Consider the difficulties your missionaries already have to encounter, because of unscriptural sentiments propagated among the heathen by those who nevertheless loved their souls. The poor, perishing idolaters are witnesses of the clashing of doctrine between Jesus Christ's men, and they ask, "_Why is this? You have come to give us a gospel which professes to make its followers 'perfect in one,' and yet you yourselves are divided._" You cannot in conscience abandon your principles, however, nor dare you, in your translations, give to a sentence or a particle one single turn, which will not fully express the mind of the Holy Spirit. Dare you, then, without feeling the most entire certainty, teach them that God says, "Remember the first day of the week to keep it holy?" The responsibility of the missionary, in this respect, is not less than where his translation is concerned. Does he feel the same awful sense of responsibility? From the heathen turn to the contemplation of the Jewish nation. The time cannot be far distant, when those who, "as touching the election, are beloved for the fathers' sakes," shall be called to behold the glory of God, in the face of Him they have so long rejected. But in order to this, a voice from the divine word cries, "Cast ye up, cast ye up, prepare the way, take up the stumbling block out of the way of my people." Have Christians seriously considered what this stumbling-block is? For our own part, we are persuaded that nothing can be more justly called by this name, than the general abandonment, on the part of Christians, of the Sabbath of the Lord. The Jews, taking it for granted, without examination, that this abandonment is really taught by the Christian religion, suppose that its author cannot be the true Messiah. They have seen, through every period of their nation's history, that God has put signal honor upon this institution. They have seen its sacredness elevated high above that of the ceremonial institutions. They have heard their prophets dwell upon the profanation of it as the crying sin of the land, on account of which the sore judgments of Heaven came down upon it. It is true, some teach that the whole Mosaic system was clothed with as much sacredness as the Sabbath; and that it was not for the sin of Sabbath breaking, any more than for a disregard of the ritual service in general, that they suffered the wrath of Jehovah. But such persons must have paid only a superficial attention to the subject. The attentive reader
