I therefore take little notice of what a man saith, though he flourisheth his matter with many brave words, if he bring not with him, 'Thus saith the Lord.' For that, and that only, ought to be my ground of faith as to how my God would be worshiped by me. For in the matters material to the worship of God, it is safest that thus I be guided in my judgment: for here only I perceive 'the footsteps of the flock' (Cant 1:8; Eze 3:11). They say further, that for God to sanctify a thing, is to set it apart. This being true; then it follows, that the seventh day sabbath was sanctified, that is, set apart for Adam in paradise; and so, that it was ordained a sabbath of rest to the saints from the beginning.
But I answer, as I hinted before, that God did sanctify it to his own rest. 'The LORD [also] hath set apart him that is godly for himself.' But again, it is one thing for God to sanctify this or that thing to an use, and another thing to command that that thing be forthwith in being to us. As for instance: the land of Canaan was set apart many years for the children of Israel before they possessed that land. Christ Jesus was long sanctified; that is, set apart to be our redeemer before he sent him into the world (Deut 32:8; John 10:36).
If then, by God's sanctifying of the seventh day for a sabbath, you understand it for a sabbath for man, (but the text saith not so) yet it might be so set apart for man, long before it should be, as such, made known unto him. And that the seventh day sabbath was not as yet made known to men.
Second, Consider secondly, Moses himself seems to have the knowledge of it at first, not by tradition, but by revelation; as it is Exodus 16:23, 'This is that [saith he] which the Lord hath said, [namely to me; for we read not, as yet, that he said it to any body else]. To morrow is the sabbath of the holy rest unto the Lord.'
Also holy Nehemiah suggesteth this, when he saith of Israel to God, Thou 'madest known unto them thy holy sabbath [by the hand of Moses thy servant]' (Neh 9:14). The first of these texts shews us, that tidings of a seventh day sabbath for men, came first to Moses from heaven: and the second, that it was to Israel before unknown.
But how could be either the one or the other, if the seventh day sabbath was taught to men by the light of nature, which is the moral law? Or if from the beginning it was given to men by a positive precept for to be kept.
This therefore strengtheneth my doubt about the affirmative of the first question, and also prepareth an argument for what I plead as to this we have now under consideration.
Third, This yet seems to me more scrupulous, because that the punishment due to the breach of the seventh day sabbath was hid from men to the time of Moses; as is clear, for that it is said of the breaker of the sabbath, 'They put him in ward, because it was not [as yet] declared what should be done to him' (Num 15:32-36).
But methinks, had this seventh day sabbath been imposed upon men from the beginning, the penalty or punishment due to the breach thereof had certainly been known before now.
When Adam was forbidden to eat of the tree of the knowledge of good and evil, the penalty was then, if he disobeyed, annexed to the prohibition. So also it was as to circumcision, the passover, and other ordinances for worship. How then can it be thought, that the seventh day sabbath should be imposed upon men from the beginning; and that the punishment for the breach thereof, should be hid with God for the space of two thousand years! (Gen 2:16,17, 17:13,14; Exo 12:43-48) and the same chapter (v 19).
