Fourth, God's giving of the seventh day sabbath was with respect to stated and stinted worship in his church; the which, until the time of Moses, was not set up among his people. Things till then were adding or growing: now a sacrifice, then circumcision, then again long after that the passover, &c.
But when Israel was come into the wilderness, there to receive as God's congregation, a stated, stinted, limited way of worship, then he appoints them a time, and times, to perform this worship in; but as I said afore, before that it was not so, as the whole five books of Moses plainly shew: wherefore the seventh day sabbath, as such a limited day cannot be moral, or of the law of nature, nor imposed till then.
And methinks Christ Jesus and his apostles do plainly enough declare this very thing. For that when they repeat unto the people, or expound before them the moral law, they quite exclude the seventh day sabbath. Yea, Paul makes that law to us complete without it.
We will first touch upon what Christ doth in this case.
As in his sermon upon the mount (Matt 5-7). In all that large and heavenly discourse upon this law, you have not one syllable about the seventh day sabbath.
So when the young man came running, and kneeling, and asking what good thing he should do to inherit eternal life, Christ bids him keep the commandments; but when the young man asked which; Christ quite leaves out the seventh day, and puts him upon the other. As in Matthew 19:16-19. As in Mark 10:17-20. As in Luke 18:18-20.
You will say, he left out the first, and second, and third likewise. To which I say, that was because the young man by his question did presuppose that he had been a doer of them: for he professed in his supplication, that he was a lover of that which is naturally good, which is God, in that his petition was so universal for every thing which he had commanded.
Paul also when he makes mention of the moral law, quite leaves out of that the very name of the seventh day sabbath, and professeth, that to us Christians the law of nature is complete without it. As in Romans 3:7-19. As in Romans 13:7-10. As in 1 Timothy 1:8-11.
'He that loveth another, saith he, hath fulfiled the law. For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not covet; and if there be any other commandment, it is briefly comprehended in this saying, Thou shalt love thy neighbour as thyself. Love worketh no ill to his neighbour: therefore love is the fulfilling of the law.'
I make not an argument of this, but take an occasion to mention it as I go. But certainly, had the seventh day sabbath been moral, or of the law of nature, as some would fain persuade themselves, it would not so slenderly have been passed over in all these repetitions of this law, but would by Christ or his apostles have been pressed upon the people, when so fair an opportunity as at these times offered itself unto them. But they knew what they did, and wherefore they were so silent as to the mention of a seventh day sabbath when they so well talked of the law as moral.
