2. A change of Sabbath is not, like the substitution of Christ, _necessary_ to the salvation of sinners; for God had saved thousands before this change is alledged to have taken place. 3. The substitution of Christ changes the moral condition _of the church only_; but the change of Sabbath would affect the moral relations of all men; for the Sabbath was made, not for the church, but "for man." 4. The evangelical doctrine of the substitutionary sacrifice of Christ, of itself, proves the impossibility of a change of Sabbath. All evangelical Christians hold, that believers are delivered, through Christ, from the _curse_ of the law--the law of the covenant of works--_but not from the obligation to obey it_. If, therefore, that law required _Adam and his posterity_ to keep holy the seventh day of the week, Christ has never redeemed them from the obligation to render "_exact obedience_," in this particular, as in every other. Do you plead, as a last resort, that, as the command not to eat of the fruit of the tree of knowledge has passed away, so it may be with the law of the seventh-day Sabbath? I reply, The cases are not parallel; for that command never was a part of the moral law. It was never written, either on man's heart, or on tables of stone; but this was. Besides, the tree of knowledge has been destroyed from the face of the earth, so that to eat of its fruit is now impossible; but the seventh day will continue to return "while the earth remaineth." Brethren, you bewilder yourselves and others, by adopting, as a moral axiom, the false principle, that whatever is in its nature positive, is _for that reason_, changeable. There is no principle more deadly than this. Do you not know, that all our hopes, as Christians, for time and for eternity, are suspended on the _immutability_ of that _positive arrangement_ between the Father and the Son, which we call the covenant of grace? Are not the decrees of God all _positive_, yet, at the same time, immutable? So, also, the _Sabbath law_, though in its nature positive, has been made unchangeable, by a solemn covenant arrangement, "in which it was impossible for God to lie." If God had not made the law, requiring the sanctification of the seventh day, an essential part of the covenant of works, your doctrine of a change of Sabbath would not be so preposterous. As it is, how can serious, thinking men, help viewing it as a monstrous and impious absurdity! CHAPTER III. _Third Reason._ My third reason for believing this proposition is, That Christ and his Apostles honored this day; and did not intimate that it would ever cease to be the Sabbath, but the contrary. 1. Christ honored this day. Luke 4:16--"And he came to Nazareth, where he had been brought up: and, as his custom was, he went into the synagogue on the Sabbath-day, and stood up for to read."
